Certain online casinos will offer Australian players a cashback bonus, which means that a percentage of the money they've lost while playing will be returned to them. For example, if you're playing online pokies and you lose $10, a 50% cashback bonus would see $5 returned to your account. Cashback bonuses are great for punters who play a lot, as they are likely to have higher losses, and while not every online casino offers one, they are increasing in popularity.
