The Interactive Gambling Act 2001\n\n It's illegal to provide some interactive gambling activities, such as 'online casinos', to someone in Australia. Examples include roulette, poker, craps, online 'pokies' and blackjack.
A player total of 21 on the first two cards is a "natural" or "blackjack", and the player wins immediately unless the dealer also has one, in which case the hand ties. In the case of a tie ("push" or "standoff"), bets are returned without adjustment.
