Australian laws block real-money online gaming
The Australian Communications and Media Authority (ACMA) has banned offshore casino operators from offering services to Australian players, meaning that even if blackjack texts and basic strategy calculators are freely downloadable, using them to wager money online is prohibited under Australian law.
What's the math behind blackjack?
Moes Almanac reports that blackjack operated per basic strategy has an approximated house edge of 0.5%. In the same conditions, without implementing a basic strategy, the house edge on a given table is roughly 2.5%. The core rules of basic blackjack strategy include doubling on 11 unless the dealer shows an ace, splitting eights and aces, and standing on 17 or higher, according to Moes Almanac and Deuces Cracked.
TrainBlackjack defines the house edge as the casino's average expected earnings per unit bet. That means the casino expects to keep 50 cents on average for every $100 wagered, assuming they play according to basic strategy.
How the table rules affect the house edge
It's important to note that the blackjack variant you choose can significantly affect the house edge. Variations with favorable rules such as 3:2 payouts for blackjack can reduce the house edge. The house edge is impacted by factors such as the payout 3:2 for blackjack versus 6:5, the number of decks, and whether or not splitting is allowed, among others, according to TrainBlackjack and Moes Almanac.
Beware of side bets
It's crucial to note that moves like insurance and even-money aren't really about protection, but in fact are side bets in disguise. According to EffortlessMath, side bets are a bad deal for the player, given their higher house edge. Essentially, it recommends avoiding side bets altogether.
What to expect from an online blackjack lobby
Online blackjack lobbies usually offer a variety of table types and variations, but Australian players are limited to demo mode. Players who want to play for real can't use sites that are operated offshore, according to ACMA.
Bonus players also often find that blackjack is barely counted when it comes to bonus clearance, if not excluded outright, due to its high RTP, as suggested by some operator guidelines.
Conclusion
While blackjack is known to have one of the lowest house edges among the offered casino table games, it's much less useful for bonus clearance. That, combined with the fact that ACMA has banned participation in offshore online gaming generally, makes it important not to allow the low house edge and rule set variations to tempt you to try anything outside of your version of the interface. If your goal is to play blackjack, do so responsibly, for fun, and adhere to the ACMA guidelines.
