Australia (AU)
Australia is the world's sixth-largest country by area and one of the most urbanised nations on Earth, with over 85% of its 27 million people living in coastal cities.
⚠️ Costly Mistakes to Avoid
The most expensive and common mistakes expats make in Australia — and exactly how to avoid them.
Not applying for a TFN immediately on arrival
Without a Tax File Number your employer must withhold tax at 47% — the top marginal rate. Banks also withhold 47% on interest. The ATO application is free and takes 10 minutes online, yet many new arrivals delay for weeks.
⚡ Massive over-withholding of tax from every payslip and bank account until TFN is provided.
📅 Deadline: Apply within your first week of arrival
✅ Apply online at ato.gov.au immediately — you only need a passport and Australian address. Your TFN arrives by post within 28 days.
Accumulating multiple superannuation accounts and paying duplicate fees
Every time you start a new job without nominating your own super fund, your employer enrolls you in their default fund. Most Australians have 2–5 super accounts from different jobs, each charging annual fees of $100–500. Over a 30-year working life, duplicate fees compound into tens of thousands of dollars lost.
⚡ Tens of thousands of dollars eroded in duplicate fees. Lost investment returns on fragmented balances.
✅ Go to myGov > ATO > Super > Consolidate super. Do this every time you change jobs. Choose one high-performing, low-fee fund and stick with it.
Paying the Medicare Levy Surcharge without realising it
If you earn over $101,000 (single) or $202,000 (family) in 2025–26 and don't hold an approved private hospital insurance policy for even one day in the financial year, you owe an MLS of 1–1.5% on your entire taxable income. This appears as a surprise tax bill at lodgement — many high earners don't realise they owe it until they receive their assessment.
⚡ $1,010–$1,515+ added to your tax bill for every year without private hospital cover above the single threshold.
📅 Deadline: Take out hospital cover before you reach the income threshold
✅ Compare policies at privatehealth.gov.au. Basic hospital cover costs $100–$200/month — far less than the MLS for most earners above the threshold.
Delaying private health insurance past your 31st birthday
Australia's Lifetime Health Cover (LHC) loading adds a 2% surcharge to private hospital insurance premiums for every year over 31 you delay taking out cover. Wait until 40 and you pay 20% more forever. Wait until 50 and you pay 40% more — for life.
⚡ Permanent premium loading of 2% per year delayed, capped at 70% but never removed until you have held cover for 10 continuous years.
📅 Deadline: Take out hospital cover before your 31st birthday (or within 1 year of becoming a permanent resident if arriving over 31)
✅ Even a basic, minimum-covered hospital policy stops the LHC clock. Compare and take out cover early — you can upgrade later.
Buying property without FIRB approval as a foreign national
Temporary visa holders and foreign nationals must get Foreign Investment Review Board (FIRB) approval before purchasing residential property in Australia. Purchasing without approval is a criminal offence. Many buyers don't realise FIRB approval is required or assume their employer-sponsored visa exempts them.
⚡ Criminal prosecution. Forced divestiture order requiring you to sell the property, often at a loss. Civil penalties up to $1,650,000.
📅 Deadline: Apply for FIRB approval before signing any contract
✅ Apply online at firb.gov.au. Fees range from $14,100 (under $1M) to over $100,000 for high-value purchases. Processing takes 30 days. Permanent residents are generally exempt — confirm your visa status first.
Paying more than 4 weeks bond or paying bond without a receipt
Landlords in most Australian states cannot charge more than 4 weeks rent as a bond. Any amount above this is illegal. All bonds must be lodged with the relevant state bond authority (NSW: Fair Trading, VIC: RTBA, QLD: RTA) — never given directly to a landlord. Many new arrivals pay excessive bonds or pay directly to landlords who pocket the money.
⚡ Loss of bond funds. No protection at end of tenancy. No dispute resolution access if bond was never lodged with the authority.
✅ Insist on a signed Form 2 (or equivalent) and confirm your bond is lodged with the state authority. Check your bond is registered at the relevant state portal. Never pay more than 4 weeks rent as bond.
Working beyond your visa work-hour conditions
Student visa (subclass 500) holders are limited to 48 hours per fortnight during term time (unlimited during official uni breaks). Working Holiday Makers have no hourly cap but are limited to 6 months with any single employer. Breaching these conditions — even by one hour — is a visa condition breach that can trigger cancellation.
⚡ Visa cancellation. Deportation. 3-year re-entry ban. Employer can also face sanctions.
📅 Deadline: Permanent — must be monitored every fortnight
✅ Track your hours weekly. Student visa holders should count hours across ALL jobs (you cannot circumvent the cap by having multiple employers). Check VEVO regularly to confirm current conditions.
Claiming DASP while planning to return to Australia on a new visa
The Departing Australia Superannuation Payment (DASP) is permanently taxed — 65% for Working Holiday Makers, 35% for others. Once you claim DASP, that super money is gone forever. Many temporary visa holders claim DASP and then return on a skilled visa — losing years of super contributions permanently.
⚡ Permanent loss of super balance. Cannot reclaim the taxed portion even if you become a permanent resident later.
✅ Only claim DASP if you are certain you will not return on a qualifying Australian visa. If you plan to return within 2–3 years, leave the super fund intact — it will remain under your TFN.
Moving into a rental without completing a condition report
In all Australian states, landlords must provide a condition report at the start of tenancy. Tenants have 3–7 days to return a signed copy with their own notes and photos. Failing to do this means the landlord's version of the property's condition stands unchallenged — setting you up for bond deduction disputes at the end of the tenancy.
⚡ Loss of entire bond ($2,000–$8,000) at end of tenancy based on uncontested landlord records.
✅ Photograph every room, every wall mark, every appliance, and every fixture on day one. Return the condition report within the required timeframe with all your notes and photos appended.
Falling victim to fake rental listings
Scammers post attractive properties on Facebook Marketplace and occasionally on legitimate portals at below-market rents. They claim to be overseas and ask for bond payment via bank transfer before you view the property. The property either does not exist or is not theirs to rent.
⚡ Loss of $2,000–$5,000 bond. No property. Identity theft if you sent ID documents.
✅ Never pay any money before viewing in person. Always verify the agent is a licensed real estate agent (check at your state's real estate regulator). Use realestate.com.au and domain.com.au over Facebook Marketplace.
Not checking that your employer is actually paying superannuation
Employer super guarantee (SG) non-compliance is widespread in Australia. An estimated $5+ billion in super goes unpaid by employers each year. Employees often do not notice because super is paid quarterly (not monthly) and does not appear on every payslip in a way that makes it easy to verify.
⚡ Lost retirement savings. After separation from the employer, recovering unpaid super becomes difficult. The ATO can recover unpaid super but the process is slow.
📅 Deadline: Check quarterly — super must be paid by the 28th day after each quarter ends
✅ Log into your super fund account quarterly and verify that employer contributions have arrived. Cross-check against your payslips (12% of ordinary time earnings from 1 July 2025). If super is missing, report to the ATO via the 'Employee Super Entitlements' tool at ato.gov.au.
Invoicing as a contractor without an ABN
If you provide services as a contractor or freelancer and do not quote an Australian Business Number (ABN) on your invoices, your client is legally required to withhold 47% of your payment and remit it to the ATO. This is the 'no-ABN withholding' rule.
⚡ 47% withheld from every invoice until you provide an ABN. Reclaiming via your tax return is possible but takes months.
✅ Register for a free ABN at abr.business.gov.au before issuing your first invoice. Takes 10–15 minutes and is instant in most cases.
Ignoring lost and unclaimed superannuation
The ATO holds over $16 billion in lost and unclaimed super — contributions from jobs where your employer lost track of you or sent your super to the ATO as a lost account. Many new and returning residents have more super than they realise.
⚡ Thousands of dollars in retirement savings sitting idle with no investment growth, eroded by government account fees.
✅ Log into myGov > ATO > Super to see all super accounts linked to your TFN, including ATO-held amounts. Claim any lost super into your chosen fund immediately.
Underestimating stamp duty surcharges for foreign buyers
Every Australian state charges an additional Foreign Buyer Duty (or Foreign Surcharge) on top of standard stamp duty for non-Australian-citizen purchasers. In 2026: NSW charges 9% surcharge (increased from 8% on 1 Jan 2025), VIC 8%, QLD 8%, WA 7%, SA 7%. On a $900,000 property in NSW, this adds $81,000 to the purchase cost — on top of standard stamp duty.
⚡ Unexpected additional cost of $40,000–$120,000+ on a typical city property purchase.
✅ Budget for the foreign surcharge before making any offer. Permanent residents are generally exempt — check your exact visa status with a conveyancer before signing. Citizenship removes the surcharge entirely.
Leaving Australia without lodging a final tax return
If you leave Australia permanently or cease to be a tax resident during the year, you must lodge a tax return covering the period you were resident. Many temporary visa holders skip this, leaving refunds unclaimed. The ATO can also raise a debt assessment years later for unfiled returns.
⚡ Unclaimed tax refunds (often $500–$3,000+ for working holiday makers). ATO debt raising for unfiled years. Possible DASP complications.
✅ Lodge your tax return online via myTax before you depart, or use a registered tax agent (H&R Block, tax agents specialising in departing residents). Mark yourself as a "foreign resident" from your departure date in the return.
Forgetting to repay HECS-HELP debt while living overseas
From 1 January 2016, Australians with HECS-HELP (student loan) debts must make compulsory repayments even while living abroad if their worldwide income exceeds the threshold. Many expats are unaware of this obligation and accrue penalties for years.
⚡ ATO debt, interest accrual (indexation is added to HECS debts each year in June), and potential legal action on return to Australia.
📅 Deadline: Lodge an Australian tax return annually even while overseas if income exceeds the repayment threshold ($67,000 in 2025–26 under the new marginal repayment system)
✅ Report your worldwide income to the ATO annually via myTax. Set up voluntary repayments via the ATO if you want to reduce the debt faster.
Misunderstanding Australian tax residency rules
Australia uses a 'facts and circumstances' test for tax residency — not just physical presence. You can remain an Australian tax resident even if you move overseas for work if Australia remains your 'home'. Conversely, new arrivals can become tax residents from day one. Non-residents pay a flat 32.5% on their first dollar of Australian-sourced income with no tax-free threshold.
⚡ Incorrect tax withholding. Underpayment or overpayment of tax. ATO audit and penalties.
✅ Seek a tax opinion from an Australian tax adviser before relocating. Departing residents should take steps to 'cease residency' clearly: close ties, sell or rent property, move bank accounts. The ATO's residency tool at ato.gov.au is a useful starting point but not a substitute for professional advice.
Assuming Medicare covers ambulance transport
Medicare does NOT cover ambulance services in most states. A single ambulance call-out costs $1,200–$2,000+ in NSW, VIC, WA, SA, and ACT. Queensland and Tasmania have state-funded ambulance services for residents. NT provides free ambulance for residents.
⚡ $1,200–$2,000+ bill per ambulance call-out in most states.
✅ Take out ambulance cover. Options: (1) Ambulance-only subscription ($40–$130/year per state — search your state ambulance service); (2) Private health insurance extras cover that includes ambulance; (3) Some unions and industry funds include free ambulance. Check your state rules at the relevant ambulance service website.
Breaking a fixed-term lease without understanding the financial consequences
Breaking a lease in Australia does not simply mean forfeiting the bond. You remain liable for rent until a new tenant is found, plus re-letting fees (equal to 1–2 weeks rent typically) and reasonable advertising costs. In a slow market this can mean months of ongoing rent liability.
⚡ Ongoing rent liability (sometimes 3–6 months) plus re-letting and advertising fees.
✅ Read your lease carefully before signing. If you need to leave, provide maximum notice and cooperate with the agent in finding a replacement tenant quickly — this is in your financial interest. Some states cap the landlord's ability to charge for re-letting.
Locking your myGov account and losing access to all linked services
Multiple failed login attempts lock your myGov account. Without access, you cannot view Centrelink payments, lodge tax returns, check your Medicare history, or access your super information. Unlocking requires a visit to a Services Australia centre with 100 points of ID — often a 2–3 hour queue.
⚡ Loss of access to all government services until physically unlocked. Can delay tax lodgement, Centrelink payments, and ATO correspondence.
✅ Set up the myGov app on your phone for app-based sign-in. Enable the authenticator option. Store your login credentials securely (password manager recommended). Never share your myGov login.
Centrelink debts for income over-reporting are common and must be repaid
If you receive Family Tax Benefit, Child Care Subsidy, or JobSeeker and your actual annual income turns out to be higher than estimated, Centrelink raises a debt for the overpayment. Centrelink balances these at tax time each year. Debts must be repaid — Centrelink can recover from future payments and tax refunds.
⚡ Unexpected Centrelink debt of $500–$5,000+ requiring repayment.
✅ Report income changes to Centrelink promptly (within 14 days). Overestimate your income when reporting to Centrelink to avoid overpayments — receiving less upfront and a refund at tax time is better than owing a debt.
Bushfire season (October–March) affects many suburban areas — know your fire danger rating and plan
Bushfires are a genuine risk in many Australian suburbs on the bush-urban interface, not just in remote areas. The fire danger rating system runs from Moderate through to Catastrophic (NSW/ACT) or Code Red (VIC). On Total Fire Ban days, lighting any open fire — including barbecues — is illegal. On Catastrophic or Code Red days: leave early. "Prepare and stay to defend" is now actively discouraged by fire agencies — leaving before fire threatens is the consistently safe choice.
⚡ Property loss, injury, or death for those who do not plan or who delay leaving on high fire danger days. Fines of up to $5,500 for lighting fires on Total Fire Ban days.
📅 Deadline: Prepare your fire plan and emergency kit before 1 October each year
✅ Check your property's fire risk at rfs.nsw.gov.au (NSW) or cfa.vic.gov.au (VIC). Sign up for your state's emergency alert system before the season. On Extreme or above days, have an agreed decision to leave before fire threatens. Know the location of your nearest evacuation centre. Download your state's emergency alert app.
Medicare enrolment is not automatic — you must actively enrol to get your card
Medicare (Australia's universal health insurance) does not automatically enrol new eligible residents. You must apply in person at a Services Australia (Medicare) centre with your visa grant letter or ImmiCard and photo ID. Your Medicare card then arrives by post in 2–3 weeks. Without a Medicare card, you pay full out-of-pocket fees ($80–150+ per GP visit) and cannot claim Medicare rebates on specialist consultations or hospital treatment.
⚡ Full out-of-pocket GP and medical costs until enrolled ($80–150+ per GP visit). No PBS (Pharmaceutical Benefits Scheme) subsidies on medications. No Medicare rebate on bulk-billed specialist referrals.
📅 Deadline: Enrol within the first week of arrival if eligible
✅ Check your eligibility at servicesaustralia.gov.au/medicare — most permanent residents are eligible immediately. Citizens of countries with reciprocal health care agreements (UK, Ireland, New Zealand, Italy, Sweden, Netherlands, Belgium, Finland, Norway, Malta, Slovenia) are also eligible. Visit your nearest Services Australia centre with your visa documents and photo ID to enrol.
National Minimum Wage: $24.95/hour (FY2025-26), rising to $26.44/hour from 1 July 2026
The Fair Work Commission set the National Minimum Wage at $24.95 per hour from 1 July 2025 (2025–26 financial year), weekly rate $948.10. On 2 June 2026, the FWC announced a 6% increase to $26.44/hour effective from the first full pay period on or after 1 July 2026. Many modern awards set higher rates for specific industries.
⚡ None — informational.
✅ If you are paid below this rate, contact the Fair Work Ombudsman at fairwork.gov.au or call 13 13 94. The FWO provides free advice and enforcement.
Super guarantee rate is 12% from 1 July 2025
The Superannuation Guarantee (SG) rate is 12% of ordinary time earnings from 1 July 2025 (2025–26 financial year). The 11.5% rate that applied in 2024–25 ended on 30 June 2025. Employers must pay at least 12% on top of your ordinary wages into your super fund. It is not deducted from your salary — it is an additional employer cost.
⚡ None — informational.
✅ Verify your super contributions by logging into your fund each quarter. Check your payslip for the super figure — it should equal at least 12% of your ordinary time earnings (not including overtime in most cases).
The tax-free threshold is $18,200 for Australian tax residents
Australian tax residents pay no income tax on the first $18,200 of income. After that, the 2025–26 rates are: 16% on $18,201–$45,000; 30% on $45,001–$135,000; 37% on $135,001–$190,000; 45% on income above $190,000. Non-residents pay 32.5% from the first dollar. The 2024 Stage 3 tax cuts restructured the lower and middle brackets significantly.
⚡ None — informational.
✅ Use the ATO tax withheld calculator at ato.gov.au to check your employer is withholding the right amount. Lodge a tax return to reclaim any over-withholding.
Most welfare payments have a 4-year waiting period for new migrants
The Newly Arrived Resident's Waiting Period (NARWP) means most new permanent residents must wait 4 years before receiving JobSeeker, Youth Allowance, Age Pension supplement, and most other Centrelink payments. Exceptions exist for some humanitarian visa holders, family members of Australian citizens, and specific hardship circumstances.
⚡ None — informational. But planning your finances around expected welfare is a common mistake.
✅ Do not rely on Centrelink payments in your first 4 years. Budget for full self-sufficiency. Family Tax Benefit and Child Care Subsidy have shorter waiting periods — check at servicesaustralia.gov.au for your specific visa subclass.
Australian energy providers estimate consumption and reconcile quarterly
Most Australian electricity and gas plans use estimated meter readings and reconcile actual usage quarterly or annually. Many expats set up direct debits and forget to monitor usage, only to receive a large reconciliation bill. Smart meters (now mandatory in VIC) eliminate this issue.
⚡ Surprise quarterly or annual reconciliation bill of $300–$1,000+ if usage exceeds estimates.
✅ Request an actual meter read at the start of your tenancy. Install your energy provider app and monitor usage weekly. In VIC, request a smart meter from your distributor if one is not already installed.
