Australian Blackjack Rules: No Hole Card, Double 9-11 and Soft 17

By David Thorne · Updated:

Quick answer: Australian blackjack is dealt with no hole card: the dealer takes a second card only after every player has finished. You can usually double only on 9, 10 or 11, standard games pay blackjack at 3 to 2, and surrender is rare. What a dealer blackjack takes from you (only your first bet, or your doubles and splits too) depends on the casino's rules.

We read the current rules documents from Crown and The Star before writing this page, and I have played these tables for years. The rules look like Vegas at first glance. They are not. Three small differences change how you should play, and most players never notice them.

No hole card: the four versions you will meet

With no hole card, you finish your hand before anyone knows if the dealer has blackjack. So what happens to the extra money you put out to double or split? Casinos answer that in four different ways:

RuleWhat a dealer blackjack takesDouble 11 against a 10?Split 8s against a 10?
OBO (original bets only) Your original bet only. Doubles and splits come back Yes Yes
BB+1 (busted bets plus one) Any busted bets, plus one unit from what is left Yes Yes
OBBO (original and busted bets only) Any busted bets, plus one unit from each hand still standing Yes No, hit
ENHC (European no hole card) Everything on the table, including doubles and splits No, hit No, hit

Definitions follow Wizard of Odds (Australian Blackjack page, updated August 2026). Under OBO you play exactly as in a hole card game. Under ENHC you play more carefully against a 10 or an ace. Our no hole card guide walks through real examples in dollars.

Which one is your casino using? The rules document says it, usually in the section on doubling and splitting. Wizard of Odds found BB+1 at Star City Sydney in 2008, but rules change, so I always read the current version before I sit down.

Soft 17: H17 vs S17

Think a 3:2 table is always the better deal? Check the soft 17 rule first.

The Star Sydney's Star Blackjack rules say the dealer stands on a hard 17 or a soft 18 (in plain words: the dealer hits soft 17). Crown Melbourne uses both versions across its games. Same casino, different tables.

3:2 vs 6:5: the rule that costs the most

Here is the difference on a A$20 bet when you are dealt blackjack:

Six dollars sounds small. It adds roughly 1.4% to the house edge, which is more than every other rule on this page put together. If a table pays 6 to 5, I walk past it.

Australia vs Vegas vs UK

RuleAustraliaLas VegasUK
Dealer hole card No (OBO, BB+1, OBBO or ENHC) Yes, dealer peeks for blackjack Usually no (ENHC)
Doubling 9, 10 or 11 only Usually any two cards Usually 9, 10 or 11
Soft 17 Varies by game H17 common on lower limits Usually stands
Blackjack pays 3:2 standard, 6:5 on some variants 3:2 or 6:5 (6:5 common on low limits) Usually 3:2
Surrender Rare Late surrender at some casinos Rare
Shuffling CSMs very common Mix of shoes and CSMs CSMs common
Local games Blackjack Plus, Australian Pontoon, Free Bet, Blackjack Challenge Free Bet, Blackjack Switch Side bets such as 21+3

"Usually" matters here. Each casino sets its own rules within what the regulator approves, so treat this table as a starting point, not a promise.

How to adjust your play for Aussie rules

  1. Find out the hole card rule (OBO, BB+1, OBBO or ENHC) before you buy in.
  2. Under ENHC, do not double 10 or 11 against a 10 or an ace. Hit instead.
  3. Under ENHC, hit 8,8 against a 10 or an ace, and hit A,A against an ace.
  4. Skip insurance. For a player who is not counting cards, it loses money over time.
  5. Avoid 6 to 5 tables and prefer S17 games when you have the choice.

Frequently asked questions

Why is there no hole card in Australian blackjack?

It is part of the approved game rules at Australian casinos, as in most of Europe and Asia. The dealer takes one card up front and draws the second after all players act, so the dealer never peeks for blackjack.

Does the dealer hit soft 17 at Crown or The Star?

It depends on the game. Star Blackjack at The Star Sydney hits soft 17. Crown Melbourne has games that stand on all 17s and variants that hit soft 17. Check the table sign or the current rules document.

Can I double on any two cards in Australia?

Usually not. Standard Australian games let you double only on a two-card total of 9, 10 or 11. Doubling after a split is usually allowed.

Does blackjack pay 3 to 2 in Australia?

Yes on standard games. Some variants pay 6 to 5, which costs you roughly 1.4% more of every bet. Read the felt before you sit down.

What happens to my double if the dealer gets blackjack?

That depends on the casino's rule. Under OBO, BB+1 and OBBO you lose only one unit on that hand. Under ENHC you lose the full doubled amount.

Is surrender allowed in Australian blackjack?

Rarely. Most standard Australian games do not offer it, and where it exists it is limited to certain variants.
