Oz Lotto odds & prize statistics
Oz Lotto draws 7 main numbers from 47. Below is every prize tier with its exact odds, the combinatorics behind the jackpot, and interactive tools to put those numbers in perspective.
Oz Lotto in plain English
An Oz Lotto line picks 7 main numbers from 47. Match everything for the jackpot — there are several smaller tiers below it too.
Oz Lotto draws 7 main numbers plus 3 supplementary numbers, and the supplementaries unlock several of the seven divisions. Because three extra balls feed the lower divisions, the division odds below are the operator's published figures rather than a simple single-ball calculation. All divisions are pari-mutuel. Draws are Tuesday. (The simulator tallies by main-number matches only.)
That single number is where every odds figure on this page comes from: you choose 7 numbers from 47 (the bonus ball is then drawn from the remaining 40), giving 62,891,499 equally-likely outcomes. Exactly one of them is the jackpot line — which is why the jackpot odds are 1 in 62,891,499.

Why there's no fixed prize table
Oz Lotto is pari-mutuel: each prize tier shares a slice of ticket sales, split between everyone who matched that tier in that draw. So the odds below are exact and fixed, but the amounts change every single draw and can't be listed as fixed figures — anyone quoting you a guaranteed payout for these tiers is guessing.
Simulate Oz Lotto draws
Every draw below is generated by your device's cryptographic RNG (crypto.getRandomValues) — the same fairness our SHA-256 generators are built on. Run a batch and watch how rarely the top tiers actually land.
Oz Lotto myths, busted
Every Oz Lotto draw is independent. A number that hasn't appeared in months is exactly as likely as any other — the balls have no memory.
Random picks and hand-chosen lines have identical odds. Quick picks only win more in total because more people use them.
A line like 1-2-3-4-5 is exactly as likely as any other. The only reason to skip popular patterns is to avoid sharing a prize if they come up.

Everything a first-time player needs — the format, the draw, and what a standard game actually costs.
To play a standard game you choose 7 numbers from 1 to 47. Each draw pulls 7 main numbers plus 3 supplementary numbers, and those supplementaries decide several of the lower divisions. Match all 7 main numbers and you win (or share) Division 1. You don’t need to match them in any order — only which numbers come out matters.
Oz Lotto moved to this 7-from-47 format in 2022 (it was previously 7 from 45, with 2 supplementaries). The extra ball and the third supplementary lengthened the Division 1 odds but added a division, which is why older odds figures you’ll find elsewhere are out of date.
When is the Oz Lotto draw?
Oz Lotto is drawn once a week, on Tuesday evening, Australian Eastern time.
The draw takes place every Tuesday at approximately 7:30pm AEST (Australian Eastern Standard Time). Entries typically close earlier in the evening, so a ticket has to be bought well before the draw to be valid for that night. Because Australia spans multiple time zones — and because AEST shifts to AEDT during daylight saving in the eastern states — the exact local cut-off varies by state. If you’re outside Australia, convert 7:30pm Sydney time to your own zone before the draw.
Times are set by the operator and can change around public holidays; always confirm the cut-off with an official outlet before playing.
System entries, explained
A system entry lets you play more than 7 numbers — covering every possible combination of them — which is the only legitimate way to shorten your odds.
A standard game is exactly 7 numbers. A System entry lets you pick more than 7, and it plays every possible 7-number combination within your chosen set. A System 9, for example, is 9 numbers played as all 36 possible 7-number lines — so it costs the same as 36 standard games, because that is literally what it is.
| System | Numbers chosen | Standard games covered |
|---|---|---|
| System 8 | 8 | 8 games |
| System 9 | 9 | 36 games |
| System 10 | 10 | 120 games |
| System 12 | 12 | 792 games |
| System 15 | 15 | 6,435 games |
Systems genuinely improve your chances — but only in proportion to what you spend, because you’re buying more lines, not beating the maths. A System 15 covers 6,435 times as many combinations as a single game and costs 6,435 times as much. There is no discount on probability; there is only more coverage for more money.
The biggest Oz Lotto jackpots
Oz Lotto holds some of the largest jackpots in Australian history. The very biggest have topped $200 million.
Oz Lotto is the game Australians associate with the country’s record-breaking jackpots. Since the 2022 format change lengthened the Division 1 odds, jackpots roll over further and climb higher before they’re won — producing several of the largest prizes the country has seen. A single Division 1 win at the top of a big run can be worth more than $200 million, shared between any winning entries.
That’s the trade-off baked into the odds: longer odds mean fewer jackpot wins, which means bigger jackpots when they finally go off. It’s the same mechanism that makes the odds section above look so daunting — the two are directly connected.

How much does an Oz Lotto ticket cost?
A single standard game is a small fixed price set by the operator, and most players buy several games on one ticket.

Exact prices vary slightly by outlet and change over time, so confirm the current price at an official outlet.
