How To Buy Bitcoin (BTC)

Tips to Find the Cheapest Way to Buy Bitcoin in Australia

So, you’re ready to buy Bitcoin in Australia, and naturally, you want to do it as cost-effectively as possible. Finding the absolute “cheapest” way isn’t always straightforward, as different platforms have different fee structures and hidden costs. However, by understanding where costs come from and applying a few key tips, you can significantly minimize your expenses.

This guide provides actionable tips to help you navigate the options and find the most cost-effective approach for you when buying Bitcoin in Australia.

Tip 1: Understand ALL the Potential Costs (It’s Not Just the Trading Fee!)

The first step is knowing where potential costs hide. Don’t just focus on the advertised trading fee; consider the entire lifecycle of your purchase:

  • Deposit Fees: How much does it cost to get your Australian Dollars (AUD) onto the exchange? Some methods are free, others aren’t. 
  • Trading Fees: The percentage or flat fee the exchange charges when you execute your buy order. This is the most commonly advertised fee.
  • Spread (The Hidden Cost): This is crucial! The spread is the difference between the price an exchange sells Bitcoin for (the ‘ask’ price) and the price it buys Bitcoin for (the ‘bid’ price) at the exact same moment. A wider spread means you’re paying a higher effective price, regardless of the trading fee. More on this below.
  • AUD Withdrawal Fees: If you plan to eventually sell and withdraw AUD back to your bank account, check if the exchange charges a fee for this.
  • BTC Withdrawal Fees: If you plan to move your Bitcoin to a personal, secure wallet (highly recommended for long-term holding, the exchange will charge a fee. This fee covers the Bitcoin network transaction cost (miner fee and potentially an additional service charge from the exchange. These can vary significantly.

Key Takeaway: Look at the total potential cost from depositing AUD to potentially withdrawing BTC or AUD later.

Tip 2: Choose Your Deposit Method Wisely

This is often the easiest cost to control:

  • Use Free Methods: In Australia, PayID/Osko and standard Bank Transfers (EFT) are typically free to use for depositing AUD onto exchanges. PayID is usually near-instant, while EFT takes 1-3 business days.
  • Avoid Card Fees: Debit card deposits usually incur high percentage fees (1.5% – 3.5%+). Credit card deposits are even worse, often attracting cash advance fees and immediate interest from your bank, on top of exchange fees (and are generally not recommended/often blocked).

Actionable Tip: Whenever possible, use PayID/Osko or EFT to deposit AUD onto the exchange to avoid unnecessary fees right from the start. 

Tip 3: Beware the Spread (Especially on Simple ‘Instant Buy’ Interfaces)

The spread can be a significant hidden cost, particularly on platforms designed for simplicity:

  • What it Means: If an exchange shows a ‘Buy Price’ of $50,500 AUD and a ‘Sell Price’ of $49,500 AUD at the same time, the spread is $1,000 AUD. Wider spreads mean you pay more when buying and receive less when selling.
  • Simple vs. Spot: Many exchanges offer both a very simple “Instant Buy” or “Quick Swap” feature AND a more traditional “Spot Trading” or “Pro” interface (with charts and an order book). The simple interfaces often have wider spreads built into the price quote, even if the advertised trading fee seems low or is bundled in. The spot market interface typically offers much tighter spreads.
  • Check Live Prices: Don’t rely solely on the advertised trading fee. Look at the actual Buy and Sell price quoted on the platform right now to gauge the spread.

Actionable Tip: Compare the live buy/sell price difference. If you’re comfortable navigating a slightly more complex interface, using the exchange’s spot trading market (BTC/AUD pair) will generally result in a tighter spread and a better effective price than using simplified “Instant Buy” features.

Tip 4: Compare Exchange Trading Fees (But Don’t Stop There!)

Trading fees definitely matter, but view them in context with the spread:

  • Fee Structures: Fees vary (e.g., 0.1% to 1%+). Some exchanges have tiered fees (lower percentages for higher trading volume). Some differentiate between ‘Maker’ fees (placing an order that adds liquidity to the book, like a limit order) and ‘Taker’ fees (taking liquidity, like a market order). Taker fees are often slightly higher.
  • The Spread Factor: Remember, an exchange with a 0.2% trading fee but a wide spread might cost you more overall than an exchange with a 0.6% trading fee but a very tight spread, especially on larger purchases.

Actionable Tip: Check the exchange’s official fee schedule, but always consider it alongside the live spread on the trading interface you plan to use.

Tip 5: Factor in Withdrawal Costs Based on Your Plans

Consider what you’ll do after buying:

  • Holding on Exchange (Not Recommended Long-Term): If leaving funds on the exchange short-term, BTC withdrawal fees aren’t an immediate concern, but AUD withdrawal fees might be if you plan to sell soon.
  • Moving to Personal Wallet (Recommended): If you plan to secure your Bitcoin in your own wallet, compare the BTC withdrawal fees between exchanges. These can sometimes differ significantly and impact your overall cost, especially if making frequent withdrawals.

Actionable Tip: Check both AUD and BTC withdrawal fees on the exchange’s fee schedule and factor them into your comparison if you plan to move your funds.

Tip 6: Consider Your Order Size and Frequency

While less critical for beginners making small initial purchases, be aware:

  • Fee Tiers: High-volume traders might benefit from exchanges with tiered fees.
  • Fixed Fees: If making very small, frequent purchases and immediately withdrawing (e.g., DCA straight to wallet), fixed withdrawal fees can add up proportionally more than for larger, less frequent transactions.

Actionable Tip: For most beginners starting small, focusing on deposit method, spread, and the base trading fee is usually most impactful.

Tip 7: Don’t Sacrifice Security and Reputation for Small Savings!

This is vital:

  • Use Reputable Platforms: Stick to well-known, AUSTRAC-registered exchanges with strong security track records.
  • Avoid Obscure Exchanges: Be extremely wary of unknown platforms advertising impossibly low fees – they could be scams or have inadequate security, putting your funds at much greater risk than paying slightly higher fees on a trusted platform.

Actionable Tip: Prioritise the security and reputation of an exchange. Saving a fraction of a percent in fees is worthless if you lose your entire investment to a hack or scam.

There’s no single magic answer to the “cheapest way,” but you are now equipped to find the most cost-effective method for your situation. By:

  • Understanding all potential costs (especially the spread).
