Moving to the U.S. from Australia: 8 First-Month Mistakes

Moving to the U.S. from Australia, the hardest part is rarely the move itself. It is the everyday systems that look familiar but operate differently, where assuming they work the Australian way leads to missed deadlines, unexpected bills, and avoidable tax problems.

This list walks through the eight areas where that happens most in your first month, from health cover and credit to tipping, tax, and your super back home.

1. Assuming you're covered if something goes wrong early

Many Australians arrive assuming there is some kind of safety net. There is no reciprocal health care agreement between Australia and the U.S. The Australian agreements cover 11 countries and the U.S. is not one of them, and your Australian Medicare does not work from overseas anyway. and "I'll just fly home if it is serious" does not help much when a single ambulance ride or ER visit can cost thousands.

There is also often a gap between landing and your employer health plan starting, sometimes a couple of weeks, sometimes the first of the following month. Sort short-term cover for that window before you fly. Once your plan starts, learn its deductible and which urgent care is in-network before you ever need one.

2. Thinking your credit history comes with you

Your Australian credit file does not come with you. U.S. credit reports only contain U.S. accounts, so on arrival you are what the Consumer Financial Protection Bureau calls "credit invisible," no matter how spotless your record at home. It bites first at the rental stage, where a blank file can mean a knocked-back application, a co-signer, or several months of rent up front.

Start building on day one. Using a secured credit card, where you put down a deposit that becomes your limit, is the usual way in, paid off in full each month, with your balance kept well under the limit. A service like Nova Credit can also carry your Australian history across to some U.S. lenders, which gives you a head start while your U.S. file is thin.

3. Expecting your Aussie license to just swap over

You cannot drive indefinitely on your Australian license. Most states give new residents a short window to switch after they establish residency, and the clock starts when you take a job or sign a lease, not when you land. Miss it and you are technically unlicensed, which can void rental-car cover and turn a routine traffic stop into a real problem.

The window varies by state. As of June 2026, California gives new residents 10 days, New York 30 days, and Texas 90 days, according to each state's DMV. Coming from Australia, expect to sit the knowledge test, since these states do not waive it for Australian licenses.

4. Banking like you're still on PayID

Australia's payment system runs years ahead of the U.S., and the difference shows up fast. Instant transfers through PayID and Osko are not the norm here. Standard US bank transfers can take one to three business days, paper checks are still used for things like rent and deposits, and paying a person usually runs through Zelle or Venmo rather than a bank-to-bank ID.

Open a U.S. bank account as soon as you can, since some banks will start one on your passport and visa while your SSN is pending. Set up Zelle through your bank's app, and don't be surprised when a landlord asks for a check. Keep a small buffer in your account for transfers that clear slower than you are used to.

5. Treating tipping as optional

At home a tip is a small thank-you for good service. In the U.S. it is expected and built into how service staff are paid, so leaving 10% or nothing comes across very differently than it does in Sydney.

A workable default: 15 to 20% at sit-down restaurants, a dollar or two per drink at a bar, and a similar percentage for delivery. Card machines usually suggest amounts, calculated before tax, and you can adjust them. The trick is to budget the tip as part of the meal rather than treating it as an extra.

6. Reading the shelf price as the price you'll pay

Every Australian price includes GST, so the sticker is the total. U.S. prices are not. Sales tax is added at the register, it varies by state and county, and there is no national rate. In a restaurant the tax lands on top of your bill before you even add the tip.

7. Assuming you only answer to the ATO

Two Australian tax habits don't carry over. First, the year is different. Australia runs July to June and the U.S. runs the calendar year, so your filing dates and deadlines shift. Second, once you become a U.S. tax resident, you report your worldwide income to the IRS, not just your U.S. earnings.

Whether you are a tax resident in year one comes down to days present. With no prior U.S. days, the practical line is 183 days in the calendar year. Once you are over the line, Australian salary, investments, and rental income can all come into play, and foreign accounts above $10,000 trigger a separate report.

8. Forgetting your super doesn't go quiet

Super is the item with no real U.S. equivalent, which is why it is so easy to overlook. The U.S. doesn't treat it like a 401(k) or recognize it as automatically tax-deferred. Once you are a U.S. tax resident, your fund is generally viewed as a foreign trust, which can mean U.S. tax on contributions or growth, plus extra reporting such as the FBAR and FATCA forms for foreign assets.

The exact treatment depends on your fund and how much control you have over it, and self-managed funds are the most complicated. None of this is cause to panic, but it is a reason to get advice early, ideally before you move rather than at tax time.

Filing your E-3 visa comes first

If you are earlier in the process and still need to file your E-3, that is the step that comes before any of it. The E-3 is open only to Australian nationals, and once you have a job offer in a qualifying role, the paperwork is the last thing standing between you and the move.

Migrate Mate's E-3 filing service handles it end to end for a flat $499. A dedicated E-3 expert prepares your Labor Condition Application, reviews your documents, completes your DS-160, and books your consulate appointment. Filings go in within one business day of collecting your documents, and every E-3 the team has filed has been approved.
