What Is a First Deposit Bonus

A casino first deposit bonus is an incentive you get for making your initial real money funding at the gaming platform. This benefit typically matches a percentage of your top-up, providing extra funds and occasionally free spins to play with.

The first deposit bonus is the most advantageous offer any best welcome bonus online casino in Australia has. Its primary goal is to attract the player to create an account and make a real money deposit. Such treats mainly apply to various games with variable or set wager sizes, such as tables and slots.

Once you clear the bonus terms, you can withdraw all your winnings. These terms involve wagering requirements, eligible games, cashout limits, and more.

Types of First Deposit Bonus in Australia

Aussies can come across many first deposit bonuses at online casinos. They may vary in type and size, but you will generally find one of the promos listed below more frequently.

Free Spins

Play Your Favourite Games These are the number of extra spins added to a specific video slot once you make a first deposit. These are played on a particular bet, and the winnings are added as bonus funds to your account.

Cashback

wager Certain casinos provide a payback on losses incurred from the initial deposit. Offering a percentage return (e.g., 10% or 20%) on losses sustained within a certain play time might serve as a safety net for novice players.

Match Bonus

win It is the most common first deposit bonus, usually set at 100% or more. If you add A$100 to your account, you will get A$100 in extra funds to play with. The first deposit match bonus can often come combined with a free spins. You may expect to receive a 100% match and an additional 50 free spins on some virtual pokies at many platforms.

How to Get the Best First Deposit Bonus Casino

Grabbing the best first deposit bonus in Australia is trouble-free. The procedure depends on the real money casinos in question, but they are generally similar. Follow the step-by-step tutorial below to get started:

  1. Pick the best first deposit bonus casino in Australia from our list.
  2. Create a user profile.
  3. Pick the offer.
  4. Read the T&Cs.
  5. Click the ‘Deposit’ button.
  6. Choose the preferred payment method.
  7. Enter the minimum deposit amount.
  8. Input the promo code (if applicable).
  9. The reward will be added to your account automatically.
  10. Select the game and start the session!

Bonus Terms & Conditions

Before funding and claiming the first deposit bonus, you must understand the specific terms and conditions associated with it. Failing to comply can lead the best Australian online casino to void your winnings. Below are some common rules you can bump into at any platform you join:

  • Wagering requirement: Before cashing out any wins from the bonus, you must wager its amount a certain number of times, known as the wagering requirement. For instance, if the rollover is capped at x30, and the reward is A$100, you must spend A$3000 of your own money before initiating the withdrawal from your online casino account.
  • Maximum bet: This point restricts the amount you can bet on a single spin or game round while playing with bonus funds. Setting it at A$5 per spin at most minimum deposit casinos and other destinations is pretty standard. However, at some brands, it can be higher, as much as A$15, while at others, it can be as low as A$0.50. We advise avoiding the latter, as it significantly restricts your ability to leverage the offer effectively and maximise your potential winnings.
  • Allowed casino games: You might be unable to use extra money or spins to play every title from the library. Casinos sometimes limit bonuses to selected games, particularly those with lower volatility and house edges, such as specific pokies.
  • Wagering contribution: The percentages that each activity contributes to fulfilling the wagering requirements vary. For example, the majority of slots may contribute 100%. Table games like blackjack, on the other hand, may only contribute 10%, meaning that each dollar wagered adds just A$0.10.
  • Maximum cashout limit: This is the maximum amount of money you can win and withdraw with a bonus offer. You won’t be able to withdraw the extra money if your winnings are above this limit.

What is RTP?

RTP, or Return to Player, is a percentage that shows how much a slot is expected to pay back to players over a long period. It’s calculated based on millions or even billions of spins, so the percent is accurate in the long run, not in a single session.


In casino games, the ‘house edge’ is the common term representing the platform’s built-in advantage. For example, it is about 0.5% in blackjack, meaning the casino holds 0.5% of all bets over time.
RTP is the key figure for slots, working opposite the house edge and showing the potential payoff to players.


Let’s consider the example: 
The Book of Dead has an RTP of 94.25%. It means that for every $100 bet, you can expect to receive $94.25 back in the long run. The remaining $5.75 is what the casino keeps.
