Ever looked at a product you use every day, an iPhone, Windows, Netflix, and thought, "Why don't I own a piece of that?" That's the pull of US stocks for many Australians. The US market is huge, packed with global brands, and offers sectors we don't have much of on the ASX.
This guide is general information, not personal financial advice. It'll walk through why Aussies buy US shares, what to watch out for, how to get started with platforms like Stake and moomoo, plus the costs, tax basics, and a simple first-buy process.
Why Australians buy US stocks (and what to watch out for)
Australia's share market can feel like a well-stocked pantry with a few missing shelves. We've got strong banks, miners, and many dividend payers. But if you want more tech, biotech, or giant consumer brands, the US is where most of them live.
At the same time, buying US shares from Australia isn't "set and forget." You're taking on currency moves, different trading hours, and sometimes bigger price swings.
The big advantages: more choice, global exposure, and sector diversification
More companies, more sectors. The US market has a deep bench in areas like software, semiconductors, healthcare, defense, and consumer brands. That means you can build a portfolio that doesn't look like a mirror of the ASX 200.
Access to household names and major ETFs. Australians often start with companies like Apple, Microsoft, or Nvidia, or they choose US-listed ETFs that hold hundreds of businesses in one fund. ETFs can be a fast way to spread risk when you're new, because one purchase can give you broad exposure.
Diversification away from an Australia-heavy portfolio. Many Australians already have Australia exposure through super, property, or local shares. Adding US stocks can reduce reliance on the same local forces (like commodity cycles or Australian bank earnings).
Simple example: Imagine you hold Aussie dividend shares for income, then add a broad US index ETF for growth exposure. If one market has a flat year, the other might still do well. It's not a guarantee, but it can smooth out the ride.
The common risks: exchange rates, higher price swings, and late night trading
Currency risk (AUD to USD). When you buy US stocks, you're buying assets priced in USD. Your return in Australian dollars depends on two things: the share price move and the AUD/USD exchange rate.
Here's the plain-English version:
- If the US stock rises but the AUD strengthens against the USD, your AUD return can shrink when you convert back.
- If the US stock rises and the AUD weakens, your AUD return can improve.
Quick example: You invest A$1,000 and it becomes US$650 after conversion (example only). If your US shares rise 10% to US$715 but the AUD strengthens before you sell, converting back could land you with less than you'd expect. The stock did its job, the currency changed the final result.
Bigger price swings in some US names. The US market has plenty of steady businesses, but it also has high-hype pockets where prices can move fast on earnings, rumors, or trend-driven trading. That's exciting until it isn't. New investors often learn this the hard way by buying after a big run-up.
Trading hours can be awkward in Australia. US markets run while most Australians sleep. Depending on daylight saving changes, US market hours are often around 12:30am to 7:00am AEST, or 1:30am to 8:00am AEDT. You don't have to stay up, but you do need to use tools like limit orders so you don't wake up to a surprise fill price.
How to invest in US stocks from Australia, step by step
If you've ever bought something online, you can handle the basics of buying US shares. The main difference is you're dealing with identity checks, currency conversion, and tax forms.
Here's a simple checklist you can follow:
- Choose a platform that offers US shares and ETFs (Stake and moomoo are popular options in Australia).
- Open an account and verify your ID (expect to upload documents and answer basic questions).
- Fund your account in AUD (bank transfer or other supported methods).
- Convert to USD (either manually or via an automatic FX feature, depending on the platform).
- Pick a stock or ETF you understand and can explain in one sentence.
- Place your order (market or limit).
- Track performance and news without checking it every hour.
- Save records of buys, sells, dividends, and currency conversions for tax time.
That's the workflow. The next two sections explain the choices that matter most.
Choose a broker: Stake vs moomoo, what matters most
You're not just picking an app. You're picking the plumbing behind your investing: pricing, FX conversion, tools, and how easy it is to stay organized.
When comparing Stake and moomoo, focus on these practical points:
FX costs and how currency conversion works. Many people fixate on brokerage but ignore FX spreads. If you convert AUD to USD often, small differences can add up.
Access and product range. Make sure you can buy the US-listed stocks and ETFs you actually want. If you're planning to stick to broad ETFs, confirm they're available.
Fractional shares. Fractional shares can help if you don't want to pay the full share price of a high-priced stock. It also makes dollar-cost averaging easier.
Order types and reliability. Limit orders, stop orders (if offered), and after-hours features can matter when markets move quickly overnight.
Research and portfolio tools. Some investors want clean simplicity. Others want deeper charts, news feeds, screeners, and paper trading.
A simple way to think about fit:
- Stake often suits investors who want a straightforward experience focused on buying and holding.
- moomoo can suit investors who like more in-app tools, data, and trading features.

No matter which platform you choose, read the latest fee schedule and FX details before you deposit. Pricing changes over time.
Make your first buy: market orders vs limit orders, and how to avoid rookie mistakes
When you're ready to place your first trade, the order type matters more than most beginners expect.
Market order: You're telling the broker, "Fill this now." It usually executes fast, but the final price can be a bit higher or lower than you saw a second ago, especially in fast markets or outside the main trading session.
Limit order: You set the maximum price you're willing to pay (or the minimum price you'll accept if selling). It gives you price control, but it might not fill if the market never hits your limit.
A few beginner-safe habits that can save you money and stress:
Start smaller than you think you should. Your first goal isn't to "win." It's to learn how pricing, FX, and order fills work with real money on the line.
Use limit orders on volatile stocks. If a stock can move 3% in a few minutes, a market order at 2:00am can surprise you.
Don't buy because it's trending. Social posts are loud, and losses are quiet. If you can't explain what the business does and why it should grow, step back.
Pick a plan before you buy. Two common approaches are:
- Buy-and-hold quality companies you'd be happy to own for years.
- Dollar-cost average into a broad ETF on a schedule (weekly or monthly), so you don't try to "time it."
Watchlists help too. Put 10 ideas on a list, track them for a month, then buy one. That delay alone filters out a lot of impulse trades.

Costs, taxes, and paperwork Australians should understand
US investing is simple once you know where the costs hide and what records you need. Most frustration comes from surprises: FX charges you didn't notice, dividend withholding, or missing paperwork at tax time.
This section is general guidance. For personal tax advice, speak with a tax agent who understands foreign investments.
Fees that matter most: brokerage, FX spreads, and ETF expense ratios
There are three cost buckets that tend to matter most for Australians buying US shares:
Brokerage (trading fees). Some brokers advertise low or zero brokerage on certain trades. Still check for other charges, because "no commission" doesn't always mean "no cost."
FX spreads and conversion fees. FX is the exchange rate you get when converting AUD to USD (and back). The spread is the difference between the mid-market rate you see on Google and the rate you actually receive. Even if it looks tiny, it can matter if you move money often.
Practical tip: If you're investing long term, it can be cheaper and calmer to convert in larger chunks less often, rather than converting small amounts every few days. Your risk tolerance and cash flow matter here.
ETF expense ratios (ongoing fund fees). ETFs have an annual fee called an expense ratio (or management fee). You don't pay it like a bill. It's reflected in the ETF's performance over time. Lower-cost broad index ETFs can be appealing when you're starting, because fees compound too.
US dividends and Australian tax: W-8BEN, withholding tax, and ATO reporting basics
If you buy US shares that pay dividends, two tax systems show up: the US system and Australia's.
W-8BEN form. Many Australian brokers will prompt you to complete a W-8BEN. This form tells the IRS you're a non-US investor, which can reduce US withholding tax on eligible dividends under the Australia-US tax treaty. In many cases, the withholding rate is commonly 15% for eligible dividends once the form is in place (rules and eligibility apply).
Withholding tax. Even with the form, some tax is often withheld before the dividend hits your account. That's normal. The key is to track it.
ATO reporting basics. Australians generally report:
- Capital gains or losses when you sell.
- Dividend income you receive (usually the gross amount, plus details of foreign tax withheld).
- Any relevant foreign tax credits (where applicable) for tax already paid overseas.
Record-keeping is your best friend. Save or export:
- Trade confirmations (buy and sell dates, quantities, prices).
- Dividend statements.
- FX conversion records (AUD to USD rate and amounts).
- End-of-year summaries from your broker.
If you've ever tried to rebuild a portfolio history from scattered emails, you know why this matters. Clean records make tax time faster and help you understand your true performance in AUD.
Conclusion
Investing in US stocks from Australia can be straightforward once you respect the basics: currency risk, overnight market hours, and the real costs that sit in FX and fees. Choose a platform that matches your style (Stake for simple long-term buying, or moomoo if you want more tools), start with an amount that lets you learn, and consider broad ETFs if you're unsure where to begin.
A simple next-step checklist: open an account, complete the W-8BEN, fund it, pick one broad ETF (or one to two high-quality stocks), then place a limit order and save your trade records. This is general information, not financial advice, but a careful first step beats a rushed one every time.
