Online gambling is legal in Australia, although not all forms of gambling are permitted. There will be certain gambling websites that are still off limits. The document that dictates gambling laws in the country, and determines whether you can enjoy online roulette real money in Australia is called the Interactive Gambling Act.
Essentially, Australia allows online sports gambling, which is one of the main sectors. However, it doesn't allow websites to operate within the country if they offer pokies, for example. Pokies are still only available in land-based casinos, at least with an official license.
Online casinos are also not allowed by individual states. However, Australia has no laws against people who choose to play live roulette online in Australia and people are free to access such websites at their own discretion.
Players do not carry any legal obligation to avoid the websites but you must be very careful in your choice as not all such casinos mean well. On the flipside, online bingo is completely legal in Australia, which could be a stepping stone to including more regulated online casino products, too.
Roulette players are welcome to explore the available options and join those casinos that they think are safe and worth their time.
