Oz Lotto Supplementary Numbers
Beyond the seven main numbers, Oz Lotto draws three supplementary numbers. They are a defining feature of the Australian game — here is what they are and what they do.
What the supplementary numbers are
After the seven main numbers are drawn, three more — the supplementary numbers — are drawn from the same 1 to 47 pool. In all, ten balls come out of the draw: the first seven are the winning numbers, and the last three are the supplementaries. Since the 2022 game change there have been three of them, up from two before.
How they affect prizes
In the Australian game, the supplementary numbers help decide several of the lower prize divisions — a player matching main numbers plus one or more supplementaries can land a higher division than the main numbers alone would give. Because you are placing a fixed-odds bet in rand rather than entering the Australian draw, any market that involves the supplementaries is priced and shown before you confirm. See the Oz Lotto guide for the full picture.
