I am not sure if there would be any reasons for it not to be available in Australia? Maybe check Steam if it is available there, but you can always check the Switch, Xbox One, Epic Game Store and GOG as well if you prefer those.

Full Game categories are almost there! Today's update added a full game timer. We are now working on the rules and will implement is as soon as possible!

Awesome to hear! Hope you join the Discord as well, cause we would love to have more people around there! Either way, good luck on the runs!
