All Australian Casino had been operating for 4 years, and it was closed in June 2017. This website held the licenses from Malta and the UK Gambling Commission. The developers left the explanation of their closure right on their website. As they say, it was related to the new licensing laws.
As for the casino itself, it was a trusted website, with a good game selection. Not that many closed casinos inform their visitors about the reasons for their closure. Moreover, the guys from the help center are still available, and if you have some questions about the remaining balance, you can send them an email, or even call them.
Probably, All Australian Casino will turn back some day, but as of now, you can pick up any other casino from our list and start playing.
