Blackjack Side Bets: Playing Perfect Pairs and 21+3 in Australia

Walk onto the blackjack floor at Crown Melbourne or The Star Sydney and you will find more than a single wager on the layout. Alongside the main bet sit optional side bets that pay out on patterns formed by the first few cards, and the two you will see on nearly every table are Perfect Pairs and 21+3. Both are quick to grasp, both resolve before the dealer draws a third card, and both reward discipline and arithmetic far more than instinct.

The appeal is obvious: a modest stake can return multiples of an even-money blackjack bet. A same-suit pair paying 25:1 looks irresistible beside a standard win at roughly one to one. The catch becomes just as obvious once you run the numbers. Side bets carry their own house edge, they compound quickly when you stake them on every hand, and they are the first thing to trim when a session starts running cold.

Australian players enjoy a few practical advantages. Recreational gambling winnings are not taxed, the legal age is 18 in every state, and each table operates under the supervision of a state gaming authority that publishes payout rules and dispute procedures. Table minimums are also gentler than the American default, with five and ten dollar stakes common and the larger limits and wider side-bet menus tucked into the late-shift and international rooms. The local lingo matters too: a twenty-dollar buy-in is a buy-in, not a stake, and "pokies" and table games sit in the same regulated venue under the same rules.

What follows is a working look at how these two blackjack side bets operate, what they genuinely pay, how they differ from the main game, and how to keep them inside a bankroll you can afford to lose. Whether you are a local squeezing in a few hands after dinner in Brisbane, a retiree with time on their hands in Adelaide, or a traveller comparing tables in Perth, the same mathematics applies.

How Side Bets Work at the Table

A side bet is an optional wager placed at the table during the betting round, usually by sliding a chip into a marked spot near the main betting area. The cards are dealt as normal, and the side wager is settled by inspecting the first two or three cards rather than by playing out the hand. Your base blackjack decision — hit, stand, double, split — is entirely separate, which is why side bets appeal to players who want something to do while the dealer works.

Because they resolve on the opening cards, side bets are largely independent of your main hand result, and that independence is exactly where the cost hides. If the dealer has a blackjack, most layouts forfeit the side wager, and on a push your side bet is usually returned rather than paid. The dealer does not have to give you a bad hand for you to lose money on the side bet; the edge is built into the price of the payout, not into the shuffle.

Think of the money as a separate game happening on the same felt. A player with a perfect main-game strategy can still bleed a session by staking the side bet on every hand, and a player who ignores the main game can occasionally get lucky on a side bet and still go broke overall. Keep the two decisions in separate mental columns and treat the side bet as entertainment you budget for, not as a strategy.

Perfect Pairs Explained

The Perfect Pairs wager is simple to describe: you bet that your first two cards will form a pair. What makes it interesting is that you choose the version. The common options are an any-pair bet, a red pair or black pair, a coloured or mixed pair, and a perfect pair, which requires the same rank and the same suit — two aces of hearts, for instance. Each version carries a different probability and a different payout, and the menus differ between operators, so read the placard rather than assuming.

Typical pricing on live blackjack follows a familiar shape. An any-pair bet pays around 1:1, a red or black pair around 3:1, a coloured or mixed pair around 8:1, and the strict perfect pair around 25:1 at many venues. The mathematics explains the spread. Two cards of the same rank and suit are a rare draw from a shoe holding six or eight decks, while an any pair comes up regularly enough to be worth roughly even money. That gap between frequency and payout is the entire game.

There is no decision to make once the wager is placed, which is precisely why sizing and selection matter. Chasing a pair with escalating bets is a losing plan, because each new hand is a fresh event with a fresh price. Choose the variant whose payout best matches the money you are willing to lose, stake a fixed amount, and let the cards fall. Some Australian tables bundle these wagers into a blackjack bonus game with a single fee covering several outcomes, and understanding whether that fee is cheaper than staking each bet separately can make a real difference over a long session.

The 21+3 Option Explained

The 21+3 wager takes the concept a step further by adding a third card to the mix. Your two opening cards plus the dealer's up card must combine into a winning pattern, and the wager pays if they do. Three cards of one suit in consecutive ranks form a three-card flush, three consecutive ranks form a straight, and an any-three option wins on a pair or any suit match. The game arrived in Australia by way of European table games and online casino versions before appearing on live floors, and it now sits on blackjack tables alongside the pair wagers.

Payouts scale with rarity. A three-card flush typically returns around 40:1, a straight around 30:1, and an any-three around 8:1, though you will find variations. Some layouts add a further tier for combinations that beat even a flush, and those rules are printed on the table's sign or on screen above the felt. Because the wager can resolve before you have decided anything about your hand, it rewards players who want a fixed stake on a pattern rather than on a strategy.

The practical warning is that 21+3 usually carries a higher house edge than the pair wagers, often in the region of nine to twelve per cent depending on the payout table, while Perfect Pairs variants tend to run closer to a couple of percentage points for the broad options and considerably more for the narrow perfect pair. Higher edge means more expected loss per dollar staked, so if you play it, play it in small amounts, and check whether the table you are sitting at is paying the better rates before you commit to a session.

Odds, Payouts and Australian Table Rules

Australian blackjack has its own conventions that affect what side bets are worth. Tables generally deal six or eight decks, the dealer usually stands on a soft seventeen at many venues, doubling after a split is often restricted, and surrender is frequently unavailable. The blackjack payout itself still runs at 3:2 at the major properties, though a growing number of tables advertise 2:1 deals that quietly change the arithmetic of the main game. Side-bet menus then shift to compensate, so a table with a generous blackjack rate often carries a leaner side-bet schedule.

Track those schedules over time rather than relying on memory from a previous visit. How operators adjust payout tables, how many side wagers they add, and which variants they promote changes faster than the base rules, and following casino market trends gives you a useful cross-check against the placard in front of you. Compare the printed payouts to the standard schedule, work out what the implied odds actually are, and remember that the printed table is the one that governs your money.

Also be clear about what a side bet pays on a push or on a dealer blackjack. Most Australian layouts void the wager in those situations, while a few refund it, and the difference is small per hand but noticeable across hundreds of hands. If you want a clean comparison between tables, calculate your expected return on a fixed unit stake and compare that with the main game's rate on the same table.

Bankroll Strategy and Responsible Play

A workable approach is simple. Decide a session bankroll you would be comfortable losing entirely, then stake the side bet at a flat percentage of it — often one to two per cent — and never raise it after a loss. No doubling down on a losing side wager, no chasing a pair that has been absent for twenty hands, no borrowing. Time limits help as much as stake limits, and setting a finish time — say, an hour before the bar closes or before you have to head home from Canberra — protects you from the slow drift that turns a fun hour into an expensive one.

Then there are the habits that protect the larger budget. Keep the side bet separate from your main blackjack money so you can see clearly when it starts to dominate. Do not play with rent, savings or the household money. Avoid alcohol while playing, since it blunts exactly the judgement the arithmetic depends on. And know where help sits in Australia: Gambling Help on 1800 858 858 offers free confidential support around the clock, BetCare provides online resources and counselling, and self-exclusion through your bank or a venue is available if the habit starts to slip.

The best session is one where the side bet stays small enough that losing it feels like a mild disappointment rather than a wound. If your reaction to a loss is anger, frustration or a plan to win it back, the stake is already too large.

Your First Hands at the Table

Start where the cost is lowest. Practise the layouts and payout schedules in a free or low-stake online blackjack version before committing money to a live table, then read the placard on the felt at Crown Perth, Treasury Brisbane or your local gaming venue and note the exact payouts for every side wager on offer. Sit at a five or ten dollar table first, stake the side bet at a single small unit, and treat each one as a separate purchase rather than part of a grand system.

Give yourself a hard stop on both cash and time, use the session to learn the flow of the game rather than to chase a result, and leave the table when your limit arrives rather than when your mood changes. Above all, keep the stake small enough that the next hand is still interesting — that is the whole point of playing these wagers in the first place.
