How do you know a site is safe?
Online wagering and sports betting is legal in Australia.
Australians can bet online at off-shore casino games, but it is illegal to provide online gaming from Australia.
If you gamble at an off-shore site, be aware that there may be fewer regulations and safeguards. People have won money at off-shore sites only to find that their stake has been stolen, they never saw their winnings and the site has been shut down.
Go to sites that have some accreditation. This might be from a body like eGOGRA who check the integrity of the online gambling provider.
