The short answer: your Australian mortgage keeps running when you move overseas. Moving doesn't end the loan contract, but it does change the admin around it. Your lender needs contact details it can actually reach you at, your bank will ask about your tax residency, and if you rent the home out, the property's use has changed. Sorting those before you leave saves a lot of friction later.
Most of us move for work, and the mortgage is one item on a long list. It's easy to leave it on autopilot. Usually that's fine. Where problems do come up, they tend to start with small things nobody told the lender, the bank or the ATO about.
Does your lender need to know you've moved overseas?
In practice, yes. The simplest reason is contact details. If a repayment goes wrong, your lender will write to you, and it writes to the address it has on file.
That matters more than it sounds. Under Australia's credit reporting rules, a lender can list a default once a payment of $150 or more is at least 60 days overdue and it has sent the required notices to your last known address. If those notices went to an old address because you didn't update your details, the lender is likely to have met its obligations anyway (OAIC, Repayment history and defaults). A letter sitting in a letterbox in Brisbane is how a small missed payment turns into a five-year mark on your credit file.
So before you go, update your residential address, email and phone number with the lender, and check that notices can reach you where you'll actually be.
Your bank will ask about your tax residency
Moving overseas can change your tax residency, and your Australian bank has its own reporting obligations around that.
Under the Common Reporting Standard, Australian financial institutions must identify accounts held by foreign tax residents and report them to the ATO, which passes the information to the relevant foreign tax authority. If you give your bank an overseas address, it may contact you to confirm your country or countries of tax residence. If you are a foreign tax resident, you may be asked for your tax identification number in that country (ATO, Foreign tax resident reporting).
Whether you are actually a foreign resident for tax purposes is a separate question from citizenship. The ATO uses its own residency tests (the resides test, the domicile test, the 183-day test and the Commonwealth superannuation test), and they aren't the same rules the Department of Home Affairs uses (ATO, Your tax residency). If you're unsure where you land, that's a conversation for a registered tax agent.
What happens to interest on your Australian savings
If you keep a savings account in Australia, the tax treatment of the interest changes once you're a foreign resident. The ATO asks foreign residents to tell their Australian bank so it can withhold tax when the interest is paid. For interest, that withholding is 10% in most cases, and you don't declare the interest in an Australian tax return. If the bank doesn't have your overseas address, it may withhold at the higher rate of 47% (ATO, Interest, unfranked dividends and royalties).
An offset account works differently. It doesn't pay you interest. The balance is set against your loan, so you're charged interest on a smaller amount. Moneysmart's example: keep $50,000 in the offset against a $750,000 loan and you pay interest on $700,000 (Moneysmart, Choosing a home loan). If you're deciding where to hold Australian dollar savings while you're away, it's worth understanding both, and checking the tax side with a registered tax agent.
If you rent the home out
A lot of Aussie expats keep the family home and rent it while they're overseas. That's a common and sensible path, but it changes three things.
1. The property's use has changed
Lenders treat a home you live in and a property you rent out as different loan purposes. A loan that was set up as owner-occupied may no longer match how the property is being used. Tell your lender about the change rather than leaving it for them to find. Your loan contract may require it. Commonwealth Bank's published mortgage terms, for example, say you must let it know if you no longer live in the home you bought with the loan, and that a home bought to live in can't be leased without its prior consent (Commonwealth Bank, Consumer Mortgage Lending Products Terms and Conditions). Other lenders' contracts differ, so check your own. The outcome varies by lender and by loan.
2. The rent is Australian income
If you're a foreign resident for tax purposes, you still declare Australian rental income in an Australian tax return (ATO, Foreign and temporary residents), and there are record-keeping and declaration rules for rental properties (ATO, Residential rental properties). We cover the expat-specific picture in Australian expat tax on investment property.
3. Selling later is a capital gains tax question
If you're a foreign resident for tax purposes when you sign the contract to sell, the capital gain on your former home may need to be included in your Australian tax return (ATO, Foreign and temporary residents). It's one of the bigger money decisions expats make, and timing matters. Our guide to capital gains tax for Australian expats explains the moving parts. The decision itself belongs with a registered tax agent.
Paying the mortgage from foreign income
Your repayments stay in Australian dollars. Once your salary is in SGD, HKD or AED, every repayment involves a currency conversion somewhere, and the exchange rate you get and the fees you pay affect the real cost. Moneysmart notes that transfer providers choose their own exchange rate and charge their own fees (Moneysmart, Sending money overseas).
Set up the transfer routine before you leave, and keep a buffer in the Australian account the repayment comes from. International transfers can take up to five business days to arrive (same Moneysmart source), and a payment made more than 14 days after the due date counts as missed on your repayment history (OAIC). For transfers home, we have a currency exchange partnership with Wise. Compare it with other providers on total cost.
Changing the loan later is harder from overseas
This is the part people don't expect. Keeping an existing loan running from overseas is simple. Changing it, whether that's refinancing, increasing the loan or restructuring, means a new application assessed on your foreign income. Fewer lenders take applications from borrowers living overseas, and your salary will usually be shaded (discounted) before it's counted. See how Australian lenders assess overseas salary and refinancing an Australian mortgage while living overseas.
If you're thinking about a refinance or a restructure anyway, it's often easier to look at it before you leave, while your income is still Australian. That's a timing question, not a recommendation, and whether it suits you depends on your situation.
Three things that are harder to sort once you've gone
1. Note the month you leave: the six-year rule
If you move out of your home and rent it out, the ATO lets you keep treating it as your main residence for capital gains tax purposes for up to 6 years while it's producing income, or indefinitely if it isn't. If you move back in and then leave again, each absence gets its own 6 years (ATO, Treating former home as main residence). The catch for expats is that foreign residents can't claim the main residence exemption on a property sold after 30 June 2020 unless they meet the life events test, and your residency is tested at the time you sign the contract to sell (ATO, Main residence exemption for foreign residents). Leaving Australia also doesn't reset your home's cost base: property in Australia isn't treated as sold when you become a foreign resident (ATO, How changing residency affects CGT).
A two-year posting has a way of becoming ten. Writing down the month you moved out costs nothing, and it's the date a registered tax agent will ask for. How the rule applies to you is their call, not ours.
2. Keep your myGov and ATO access working
myGov says that before you travel overseas you may need to change how you sign in (myGov, Accessing myGov while overseas). If you sign in with a code sent by SMS, you need your registered Australian mobile number with international roaming turned on (myGov, Use a code sent by SMS). If you plan to let that number go, set up another sign-in option while you're still here. You'll still need access for Australian tax returns on rental income, and it's much easier to change onshore.
3. Borrowing above the usual expat limits is generally an onshore conversation
Published lender policies we've reviewed commonly set a lower maximum loan-to-value ratio for Australians living overseas than they offer the same borrower living in Australia, and some lenders won't consider an application without a current Australian residential address. That's lender policy rather than a mortgage insurance rule. So if you're planning to buy or refinance with a smaller deposit or a higher loan relative to the property's value, the range of options is generally wider while you still live and earn in Australia. Whether it suits you depends on your situation, and it's not a reason to borrow more than you need.
If money gets tight while you're away
Relocations cost more than planned, and contracts sometimes end early. If you're struggling with repayments, contact your lender's hardship team early. Your lender must tell you the outcome of a hardship request in writing within 21 days (Moneysmart, Problems paying your mortgage), and it can't list a default on your credit report while it's deciding the request (OAIC). Time zones make this easy to put off. Don't.
A before-you-go checklist
- Update your address, email and phone number with your lender and every Australian bank.
- Answer your bank's tax residency questions accurately, including your foreign tax number if you have one.
- Decide how repayments will be funded and keep a buffer in the Australian account they come from.
- If you're renting the home out, tell your lender, and talk to a registered tax agent about the rent and a future sale.
- Download recent loan statements. You'll want them for any future application.
- If a refinance is on your mind, look at it before your income changes currency.
- Write down the month you move out of your home, for the six-year rule, and talk to a registered tax agent before you decide to keep or sell.
- Set up a myGov sign-in option that works overseas before you let your Australian mobile number go.
- If you're thinking about borrowing with a smaller deposit, look at it before you leave.
Frequently asked questions
Can I keep my Australian mortgage if I move overseas?
Yes. Moving overseas doesn't end an existing loan. You keep making repayments under the same contract. What changes is the admin: contact details, tax residency information with your bank, and, if you rent the property out, how the property is used.
Do I have to tell my bank I'm moving overseas?
It is worth updating your contact details, because default notices sent to your last known address can still be valid if you didn't update it (OAIC). Your bank may also contact you to confirm your tax residency under the Common Reporting Standard once it has an overseas address on file (ATO).
What happens to the interest on my Australian savings account when I move overseas?
Once you're a foreign resident for tax purposes and your bank has your overseas address, it generally withholds 10% tax from the interest, and you don't declare that interest in an Australian tax return. Without your overseas address it may withhold 47% (ATO).
What is the six-year rule if I move overseas and rent out my home?
The ATO lets you keep treating a former home as your main residence for capital gains tax for up to 6 years while it's rented out. But if you're a foreign resident when you sign the contract to sell, you generally can't claim the main residence exemption unless you meet the life events test (ATO). Talk to a registered tax agent before you decide to keep or sell.
Can I refinance my Australian home loan after I move overseas?
Often, yes, but it's a new application assessed on your foreign income, and fewer lenders accept borrowers who live overseas. Lender policy and your income structure decide what's possible.
