Powerball (Australia) odds — every division, derived

Every figure on this page is calculated from the game's published rules. The operator's own odds page is linked below as verification — but the working is here, on this page.

The combinatorics

A standard entry picks 7 numbers from 35 plus 1 from a separate pool of 20. The number of possible combinations is:

C(35, 7) = 6,724,520 × C(20, 1) = 134,490,400

"Winning combinations" counts how many of the possible outcomes land in that division. "Operator says" is the operator's published figure — shown so you can check us against them (small differences are their rounding).

Odds of winning any prize

1 in 43.98

Sum of all division probabilities — usually the number the ads quote.

Odds of the top prize

1 in 134,490,400

One standard game. Two games doubles it — and it's still tiny.

How long are these odds? Winning the top prize is about as likely as calling 27 coin flips in a row correctly (227 134,490,400). If you bought one line every draw, at two draws a week you would expect one top-prize win roughly every 1,293,177 years.
