How Powerball AU Prize Tiers Work
While the jackpot requires a perfect match, Powerball AU awards prizes for partial matches as well. Matching 5 of 7 main numbers is far more likely than matching all 7, which is why lower-tier prizes are smaller but won more frequently. The Powerball adds complexity — since it is drawn from a separate pool of 20 numbers, it effectively multiplies the number of possible outcomes and creates additional prize tiers.

Our calculator uses BigInt arithmetic to handle the extremely large factorials involved, ensuring every odds figure is mathematically exact. Play responsibly and treat the lottery as entertainment.

How are Powerball AU odds calculated?
Powerball AU odds use the mathematical combination formula C(n,k) = n! / (k!(n-k)!). The total number of main-ball combinations is C(35, 7). This is then multiplied by 20 possible Powerball values to get the overall jackpot odds. Each unique ticket covers exactly one of these combinations.
What are the chances of winning any Powerball AU prize?
The odds of winning any prize in Powerball AU are much better than the jackpot odds. Lower prize tiers require matching fewer numbers, and the probability increases substantially as the required matches decrease. See the prize tier table above for exact odds at every level.

Yes, each additional unique Powerball AU ticket gives you one extra chance. Buying 10 tickets makes you 10 times more likely to win than buying one. However, even with multiple tickets, the odds remain extremely long for the jackpot. The expected return on a lottery ticket is almost always negative.
