Australian Lottery Odds Compared
See which major Australian lottery has the shortest Division 1 odds, how likely each game is to return any prize, and what those large numbers mean in ordinary language.
Which Australian lottery has the best odds?
For Division 1, Saturday Lotto and Weekday Windfall have the shortest odds among the five major draw games compared here. Each is 1 in 8,145,060 for one standard game. That does not automatically make either one the “best” game: the top prizes, draw frequency and entry formats are different.
Saturday Lotto has the shortest published overall odds in this five-game comparison.
Its Division 1 odds are the longest here, but its rolling jackpots can become the largest.
Australian Division 1 odds
A smaller “1 in” number means a shorter chance. Division 1 still requires one complete winning combination in a single game—numbers cannot be combined across separate lines.

How much harder is each Division 1 win?
The bars use Saturday Lotto and Weekday Windfall as the starting point. Australian Powerball’s Division 1 odds are about 16.5 times longer than either six-from-45 game.
Odds of winning any prize
Overall odds include every published prize division, from the smallest qualifying match through to Division 1. They say nothing about the likely value of the prize.
| Game | Any-prize odds | Prize divisions | Smallest qualifying match |
|---|---|---|---|
| SATSaturday Lotto | About 1 in 42 | 6 | 3 winning numbers |
| PBAustralian Powerball | About 1 in 44 | 9 | 2 winning numbers + Powerball |
| OZOz Lotto | About 1 in 51 | 7 | 3 winning + supplementary |
| SFLSet for Life | About 1 in 51 | 8 | 3 winning + supplementary |
| WWWeekday Windfall | About 1 in 86 | 6 | 1 or 2 winning + both supplementaries |
Overall odds are rounded operator figures based on one standard game. A shorter overall chance does not mean a profit is likely; most winning combinations are in the lower prize divisions.
What if you play more than one game?
Enter the number of different standard combinations you hold in the same draw. The calculator shows the chance that at least one of them wins Division 1. It does not treat repeated copies of the same numbers as extra coverage.
Maximum: 100,000 combinations. Results are mathematical probabilities, not a prediction of a future draw.
Division 1 chance in one draw
Four things the headline odds do not tell you
Shorter odds do not mean a larger prize
Weekday Windfall has much shorter Division 1 odds than Powerball, but its regular top prize is fixed at $1 million while Powerball can build into a much larger jackpot.
“Any prize” may mean a small prize
The overall figure groups every prize division together. It should not be read as the chance of winning more money than you spend.
Every valid line has the same chance
QuickPick, birthdays, hot numbers and carefully chosen patterns do not change the mathematical probability of a valid standard game.
System entries buy more combinations
A System entry can shorten the effective odds because it contains several standard combinations. It also costs more because you are buying more games.

Australian lottery odds FAQs
Which Australian lottery is easiest to win?
Among the five major draw games on this page, Saturday Lotto and Weekday Windfall have the shortest Division 1 odds at 1 in 8,145,060 per standard game. Saturday Lotto has the shortest published overall chance of any prize at approximately 1 in 42.
Which Australian lottery has the worst jackpot odds?
Australian Powerball has the longest Division 1 odds in this comparison at 1 in 134,490,400 per standard game. It is also the game designed to produce the largest rolling Australian jackpots.
Do more games improve my lottery odds?
Different standard combinations give you more chances in that draw. Ten different games provide ten distinct chances; buying the same line twice does not cover a new combination, although it may duplicate the prize attached to that line.
Are QuickPick odds worse than chosen numbers?
No. Every valid standard combination has the same mathematical chance in a fair random draw. QuickPick changes how the numbers are selected, not the odds of that combination.
Why are Powerball odds much longer?
Division 1 requires two things in the same game: all seven winning numbers from the main 35-ball draw and the correct Powerball from a separate 20-ball draw. That extra separate match stretches the odds to 1 in 134,490,400.
Does playing every draw make a win due?
No. Each valid combination faces the same odds in each new draw. A long run without a win does not make a particular line more likely to win next time.
