The Powerball Australia odds calculator shows why the jackpots get so big. You pick 7 numbers from 35 and a Powerball from 20. All eight is Division 1: 1 in 134,490,400 per game. Get the seven without the Powerball and it’s 1 in 7,078,442, which is still a life-changing Division 2. The free calculator above works out every match, plus your chance over many games and draws.
Powerball Australia odds for every match
The Powerball comes from a separate barrel of 20. Needing it divides your odds by 20, and needing to miss it costs only 1 in 20.
| Match | Odds per line |
|---|---|
| 7 + Powerball | 1 in 134,490,400 |
| 7 | 1 in 7,078,442 |
| 6 + Powerball | 1 in 686,176 |
| 6 | 1 in 36,115 |
| 5 + Powerball | 1 in 16,943 |
| 5 | 1 in 892 |
| 4 + Powerball | 1 in 1,173 |
| 4 | 1 in 61.7 |
| 3 + Powerball | 1 in 188 |
| 3 | 1 in 9.9 |
For the main numbers: C(7, m) × C(28, 7 − m) ÷ C(35, 7). Then × 1/20 with the Powerball or × 19/20 without.
The hardest jackpot in Australia
134 million to one is about 16.5 times harder than Saturday Lotto and twice as hard as Oz Lotto. That’s on purpose. Long odds mean jackpots roll over and grow, and a $100 million Thursday gets everyone buying.
A PowerHit entry that covers all 20 Powerballs cuts the odds to about 1 in 6.7 million, but it costs 20 games’ worth. The odds per dollar spent don’t improve.
Compare with the Oz Lotto odds calculator. For a random line, the lottery number generator has Australian Powerball built in.
