Video Guide: Online Blackjack in Australia
Watch our quick guide to playing online blackjack in Australia, covering the best variants, basic strategy and how to choose a safe site for real money play.
How Online Blackjack Works
Online blackjack follows the same rules as the classic casino card game. The goal is to beat the dealer by getting a hand value as close to 21 as possible without going over. Cards 2-10 are worth their face value, face cards (J, Q, K) are worth 10, and Aces can be worth 1 or 11.
Australian online casinos use Random Number Generators (RNG) for digital blackjack and real dealers with live-streamed video for live blackjack.
Popular Blackjack Variants
Classic Blackjack
The standard version with one or more decks. Simple rules make it perfect for beginners. House edge: around 0.5% with basic strategy.
European Blackjack
Played with two decks. The dealer does not receive a hole card until the player has acted.
Multi-Hand Blackjack
Play up to 5 hands simultaneously. Great for experienced players.
Live Dealer Blackjack
Play with a real dealer via live video stream. The most immersive online blackjack experience.
Blackjack Switch
You play two hands and can swap the top cards between them.
Basic Blackjack Strategy
Using basic strategy significantly reduces the house edge:
- Always stand on 17 or higher
- Always hit on 8 or below
- Double down on 11 when the dealer shows 2-10
- Split Aces and 8s
- Never split 10s or 5s
- Stand on soft 18 or higher
Live Dealer vs RNG Blackjack
Live Dealer Blackjack features a real person dealing cards in a studio, streamed in real-time. It offers social interaction and authentic casino atmosphere. Minimum bets are typically A$5-A$25.
RNG Blackjack uses software to deal cards randomly. Games are faster, minimum bets are lower (often A$1), and you can play at your own pace.

Blackjack Payout Structure
Understanding how blackjack pays is essential for managing your bankroll. Here are the standard payouts at Australian online casinos:
| Outcome | Payout | Example (A$10 bet) |
|---|---|---|
| Blackjack (natural 21) | 3:2 | Win A$15 |
| Regular win | 1:1 | Win A$10 |
| Insurance (dealer has A) | 2:1 | Win A$10 on A$5 side bet |
| Push (tie) | 0 | Bet returned |
| Loss | –1 | Lose A$10 |
⚠️ Avoid 6:5 blackjack tables. Some casinos pay only 6:5 for a natural blackjack instead of the standard 3:2. On a A$10 bet that is only A$12 instead of A$15. This nearly doubles the house edge from ~0.5% to ~1.4%. Always look for 3:2 tables.
Popular Blackjack Side Bets
Side bets add extra excitement to blackjack. They are placed before cards are dealt and resolve independently from your main hand. Keep in mind that side bets carry a higher house edge than the base game.
21+3
Combines your two cards with the dealer upcard to form a three-card poker hand. Payouts vary by combination:
- Flush – all three cards same suit → 5:1
- Straight – three consecutive cards → 10:1
- Three of a Kind – three same-value cards → 30:1
- Straight Flush – consecutive and same suit → 40:1
- Suited Three of a Kind – identical cards → 100:1
House edge: approximately 3.2%.
Perfect Pairs
Pays out if your first two cards form a pair:
- Mixed Pair – same value, different colour → 5:1
- Coloured Pair – same value and colour → 12:1
- Perfect Pair – identical cards → 25:1
House edge: approximately 4–6% depending on deck count.
Insurance
Offered when the dealer shows an Ace. You bet half your original wager that the dealer has blackjack. Pays 2:1 if correct. Statistically, insurance is a bad bet – the house edge is around 7.4%. Basic strategy says: never take insurance.
Bet Behind
Available at live dealer tables. You bet on another player hand. Useful when all seats are taken, but your outcome depends entirely on their decisions.
