Oz Lotto odds at a glance
A standard Oz Lotto game contains seven selected numbers from 1 to 47. Division 1 means matching all seven winning numbers in that one game.
All seven winning numbers must appear together in the same standard game.

What if you play more Oz Lotto games?
More different standard combinations give you more chances to contain the seven winning numbers. The calculator below shows the Division 1 probability for a chosen number of distinct games.

Important: this assumes every game is a different seven-number combination. Buying the identical line twice does not double the chance that the numbers are drawn; it duplicates the prize entitlement on that line if it wins.
The official Division 1 probability for one standard Oz Lotto game.
Ten different combinations give ten times the single-game chance.
The chance increases, but Division 1 remains a very unlikely outcome.
How supplementary numbers affect a prize
Oz Lotto draws ten balls from 47. The first seven are the winning numbers and the final three are supplementary numbers. You do not select three extra supplementary numbers when entering a standard game.
Supplementary numbers matter in Divisions 2, 4 and 7. For example, six winning numbers without a supplementary number is Division 3; six winning numbers plus at least one supplementary number moves that game into Division 2.
Standard, QuickPick, System and Pick entries
The odds table above is deliberately based on one standard seven-number game. Other Oz Lotto entry types can contain multiple underlying standard combinations, so they should be compared by how many combinations they actually create.
You choose seven numbers from 1–47. The Division 1 odds for that game are 1 in 62,891,499.
The lottery system chooses the numbers. A randomly generated standard game has exactly the same probability as a manually selected standard game.
These entry types package multiple standard combinations. Their coverage and price rise with the number of underlying games.
Why every valid seven-number combination starts equal
The Division 1 odds come from the number of different seven-number combinations that can be formed from 47 numbers. Historical frequency does not enter the calculation.
A number that appeared last Tuesday is not “used up”, and a number that has not appeared for several weeks is not mathematically “due”. Before an independent draw, every valid seven-number combination has the same chance of being the seven winning numbers.
That is also why a random Oz Lotto number generator can be useful for creating correctly formatted combinations without pretending to forecast the result.
Put the odds in context
Oz Lotto’s Division 1 odds are longer than Saturday Lotto but shorter than Australian Powerball. Different games use different number matrices, so comparing jackpot size alone does not compare the probability of winning it.
| Australian game | Division 1 odds · one standard game |
|---|---|
| Saturday Lotto | 1 in 8,145,060 |
| Oz Lotto | 1 in 62,891,499 |
| Australian Powerball | 1 in 134,490,400 |
These comparisons describe the mathematical chance per standard game. They do not account for ticket price, jackpot size, prize-pool structure or how many other entries might share a prize.
Oz Lotto prizes and odds FAQs
What are the odds of winning Oz Lotto Division 1?
The official Division 1 odds are approximately 1 in 62,891,499 for one standard seven-number Oz Lotto game.
What are the overall odds of winning any Oz Lotto prize?
Lotterywest publishes the overall chance of winning any Oz Lotto prize as approximately 1 in 51 for one standard game.
What do I need to match to win Division 1?
All seven winning numbers must appear together in the same standard game. Supplementary numbers are not required for Division 1.
Do ten Oz Lotto games give ten times the chance of one game?
If all ten games are different seven-number combinations, the Division 1 probability is ten times the probability of one standard game, or about 1 in 6.29 million. The cost also increases with the number of games played.
Does buying the same Oz Lotto line twice improve the chance of matching Division 1?
No. The same seven-number combination has the same chance of being drawn whether it appears on one ticket or more than one. Duplicate entries can increase the amount held on that combination if it wins, but do not create another distinct combination.
Are QuickPick numbers less likely to win than numbers I choose myself?
No. A valid randomly generated seven-number combination and a valid manually selected combination have the same probability before the draw.
Can one standard Oz Lotto game win more than one division?
No. The game rules provide one prize division for a standard entry. A combination qualifying for a higher division is not also paid separately in each lower division it could partially satisfy.
