A special cashback King Billy bonus Australia allows you to receive from 3 to 13% of your losses. The percentage varies depending on your current VUP status. In particular, players will receive 3% cashback when they join the VIP club and their net losses exceed A$750. However, when they get higher and reach King/Queen level, their cashback will be 13%. Keep in mind that there will be no wagering requirements in this case.
