If you're holding USD in your Australian bank account—like with Commonwealth Bank (CommBank)—and want to buy Bitcoin (BTC) or other cryptocurrencies, you’re likely concerned about minimizing fees. Converting USD to AUD first and then purchasing crypto can result in double costs: foreign exchange (FX) fees from the bank and trading fees on exchanges. But there’s a smarter way.
This guide walks you through a proven, low-cost method to convert USD directly into crypto—bypassing unnecessary AUD conversions—and keep total fees around 1% or less, depending on your setup.
Why Avoid Converting USD to AUD First?
Many Australians assume they must convert foreign currency like USD into AUD before buying digital assets. However, this approach often leads to high hidden costs:
- Bank FX fees: CommBank typically charges up to 4% for currency conversion.
- Spread markup: Banks offer poor exchange rates. For example, while the market rate might be 1 USD = 1.36 AUD, CommBank may only give 1.30 AUD per USD.
- Crypto exchange fees: After conversion, buying BTC or USDT on local platforms adds another 1% fee.

This means you could lose over 5% of your capital before even entering the crypto market. That’s avoidable.
The Smart Path: Use a Crypto Exchange That Accepts USD Deposits
The key to reducing fees is avoiding AUD conversion altogether. One platform that supports direct USD deposits in Australia is Independent Reserve (IR).
Why Independent Reserve Works for USD Holders
- Supports USD bank transfers from overseas or Australian foreign currency accounts.
- Regulated Australian exchange with strong security practices.
- Allows purchase of major cryptocurrencies like USDT, BTC, ETH, and more using USD.
- Low trading fees (~1%) with tight spreads.
While most local exchanges only accept AUD, IR stands out by enabling USD funding—making it ideal for users with USD balances in banks like CBA.
Step-by-Step: How to Transfer USD from CommBank to Independent Reserve
Follow these steps to move your USD and buy crypto efficiently.
Step 1: Open an Account on Independent Reserve
Sign up at independentreserve.com (referral codes removed per guidelines).
As an Australian citizen or permanent resident, you’ll need to verify your identity:
- Upload a government-issued ID (e.g., passport or driver’s license).
- Provide proof of address if required.
- Verification usually takes 1–2 business days.
Note: While the original poster used a referral code, such promotions are excluded here to comply with content policies.
Step 2: Request a Dedicated USD Deposit Account
Independent Reserve does not allow direct USD deposits through standard banking interfaces. You must contact their support team to receive:
- A dedicated NAB-based USD account (BSB + 10-digit alphanumeric account number).
- SWIFT/BIC code for international transfers.
- Unique reference number for payment tracking.
This account is hosted via National Australia Bank (NAB), but structured for foreign currency settlements.
Step 3: Initiate International Transfer from CommBank
Log into your CommBank online banking portal and navigate to:
Pay & Transfer > International Money Transfer > Send to Someone New
Fill in the details provided by Independent Reserve:
| Field | What to Enter |
|---|---|
| Recipient Bank Code | Use the SWIFT/BIC code (e.g., NATAAU33XXX) |
| BSB | May be accepted, but SWIFT is correct for cross-border |
| Account Number | The 10-digit alphanumeric NAB account |
| Reason for Transfer | Select “Other” and enter the reference number given by IR |
⚠️ Important: Always include the correct reference number. Missing or incorrect references can delay or block deposits.
💡 Pro Tip: Even though you're sending within Australia (NAB to NAB), CommBank treats this as an international transfer because it involves foreign currency. Use the SWIFT code, not just the BSB.
Step 4: Wait for Funds to Arrive
Processing time: 3–4 business days
Fees: Around $11 USD per transfer (charged by CommBank)
Once credited, log into Independent Reserve and confirm your USD balance. You can now trade USD for USDT, BTC, or other supported cryptocurrencies.

Minimize Trading Costs: Buy USDT First, Then Transfer
To get the best value:
Buy USDT (Tether) on Independent Reserve using your USD.
- Lower spread and higher liquidity than BTC.
- Trading fee: ~1%.
Withdraw USDT to a larger exchange like OKX, Bybit, or Kraken.
- These platforms offer better BTC/ETH pricing and advanced tools.
- Trade USDT for BTC or any other crypto at competitive rates.
Avoid buying BTC directly on Independent Reserve—trading volume is low, leading to wider spreads and slippage.
Frequently Asked Questions (FAQ)
Q1: Can I use this method if I’m a Permanent Resident (PR)?
Yes. Most Australian crypto exchanges, including Independent Reserve, accept both citizens and permanent residents for verification. You’ll need valid ID and may be asked for residency documentation.
Q2: Do I have to pay tax when buying BTC with USD?
Buying crypto isn’t a taxable event in Australia. However, future actions like selling, swapping, or spending crypto trigger Capital Gains Tax (CGT). Keep records of all transactions, including bank transfers and exchange activity.
Q3: Why didn’t I need to use the SWIFT code during my transfer?
Some users report success using only the BSB and account number, especially if both banks are domestic (e.g., NAB-to-NAB). However, since this is a foreign currency transfer, the SWIFT code ensures proper routing. Relying solely on BSB may work occasionally but isn't guaranteed.
Q4: Are there alternatives to Independent Reserve?
Currently, few Australian exchanges support direct USD deposits. Some global platforms allow international wire deposits in USD, but require non-AUD on-ramps. Always check compliance with local banking policies.
Q5: Can I deposit USD from a CommBank foreign currency account?
Yes. If you hold USD in a CBA Multi-Currency Account, you can initiate an international wire transfer from that balance without converting to AUD—preserving your principal and cutting FX fees.
Optimize Further? Consider Stablecoins and Global Exchanges
For frequent traders or those managing larger sums:
- Explore global exchanges that accept SWIFT deposits in USD.
- Use stablecoins like USDT or USDC as a bridge between fiat and crypto markets.
- Leverage platforms with deeper liquidity and lower trading fees.
👉 Access one of the world’s top-rated exchanges for fast, low-fee crypto trading.
Final Thoughts: Keep Fees Low, Stay Compliant
You don’t need to lose 4–5% in fees just because you’re starting with USD in Australia. By using Independent Reserve as a gateway and transferring funds correctly via SWIFT, you can:
- Avoid costly bank FX markups.
- Enter the crypto market with minimal friction.
- Maintain full tax compliance with clear transaction records.
Whether you're investing $10,000 or $300,000 in USD, this strategy scales efficiently—especially when you prioritize stablecoins and high-liquidity trading pairs.
With careful planning and the right tools, turning USD into Bitcoin in Australia doesn’t have to be expensive—or complicated.
