A$5 Million

While reading, please bear in mind that the currency for this page is A$.

Oz Lotto is drawn once a week at 9:30pm AEDT on a Tuesday. Ticket sales close an hour before the draw, which is televised on 7TWO and posted online in video format. A single Oz Lotto ticket costs between A$1.10 and A$1.45, depending on the ticket agent’s commission. There are online, telephone and SMS services to check the draw results, making it easy to find out if you're a winner.

Oz Lotto is unusual in that there is a variety of ways to take part, and it is normal for a single entry to include a combination of numbers or multiple individual lines - so much so that the game odds are often quoted on the assumption that you will have bought a combination of 12 tickets instead of just one.

Number of Lines

How to Play

An Oz Lotto draw will see nine balls chosen from a set of 1-45. The first seven balls drawn form the main winning line for each draw, while the remaining two are supplementary numbers. Match one or both of these supplementary numbers and you have the chance to win a better prize if you also match three, five or six of the main balls.

Unusually, there is no specific prize for matching either or both of the supplementary numbers along with four of the main draw balls, and also no added bonus if you match both supplementary numbers instead of just one. Oz Lotto has several other ways to play, which are outlined under Supplementary Games below.

Why to Play

There are a number of reasons Oz Lotto is a favourite amongst players, with one of them being the different ways of entering the draw. These are ideal for experienced lottery players, as they give you ways to enter a combination of tickets to maximise your payout, without having to manually enter each permutation of your chosen numbers.

There's the option of a QuickPick if you have no specific attachment to certain numbers, and with no upper limit on the jackpot, it can range anywhere from the guaranteed minimum of A$2 million, right up to over A$100 million.

Another unusual aspect of Oz Lotto is that you can claim prizes by post, and have them paid via cheque or electronic funds transfer, making this an especially good option if you are playing from outside of Australia by lottery courier service.

Supplementary Games

With Oz Lotto, rather than supplementary games there are a variety of ticket types available to choose from.

‘System’ tickets enter multiple combinations of the same set of numbers. So, for example, the numbers 1, 2, 3, 4, 5, 6 and 7, along with a line containing 1, 3, 4, 5, 6, 7 and 8, a line containing 1, 2, 4, 5, 6, 7 and 8, and so on.

Below is a list of all systems available on the Oz Lotto game and their respective entry equivalents.

System Type Entry Equivalent
System 8 8
System 9 36
System 10 120
System 11 330
System 12 792
System 13 1,716
System 14 3,432
System 15 6,435
System 16 11,440
System 17 19,448
System 18 31,824
System 19 50,388
System 20 77,520

If you were to pick a system 8 entry for Oz Lotto, your ticket entries may look something like this:

1 2 3 4 5 6 7 _

1 2 3 4 5 6 _ 8

1 2 3 4 5 _ 7 8

1 2 3 4 _ 6 7 8

1 2 3 _ 5 6 7 8

1 2 _ 4 5 6 7 8

1 _ 3 4 5 6 7 8

_ 2 3 4 5 6 7 8

This rapidly increases the number of lines you need to play to cover every combination - up to 77,520 lines to cover all the possible seven-number combinations if you choose the maximum permitted 20 numbers on a 'System 20' ticket. There's an increase in cost too, but if you make a winning match, you are much more likely to claim multiple prizes across several of your entered lines.

'Pick' tickets take a different approach: you choose five or six balls and the system automatically plays these in a combination with the remaining numbers in the draw. This way, you know that you will match at least one or two of the winning numbers on the night. That is still not enough to guarantee a win, but it vastly improves your odds of matching enough of your own chosen numbers to earn yourself a payout.

Prizes and Odds of Winning

Each prize division is calculated using a percentage of the total prize fund - as shown in the table below - with the exception that the jackpot has a guaranteed minimum of A$2 million and continues to rollover until it is won.

The exact payout can change depending on the prize fund for that draw and on the number of winners in that prize division. The prize amounts will only be revealed once the draw has taken place and the number of winners is known.

Oz Lotto is unusual in that the odds of winning shown in the table below are for a single play, but you will often see odds given based on buying a regular QuickPick, which is a set of 12 tickets. For comparison, the table below also shows how playing a 12-ticket set in this way affects your chances of winning - although of course it also costs more to enter multiple times.

Match Prize (% of fund) Odds Odds per 12 tickets
7 40% 1 in 45,379,620 1 in 3,781,635
6 + 1 or 2 supp. numbers 1.7% 1 in 3,241,401 1 in 270,117
6 3.5% 1 in 180,078 1 in 15,007
5 + 1 or 2 supp. numbers 1.8% 1 in 29,602 1 in 2,467
5 2.1% 1 in 3,430 1 in 286
4 24% 1 in 154 1 in 13
3 + 1 supp. numbers 26.9% 1 in 87 1 in 8

Payment Options

Smaller prizes can be claimed at participating retailers, up to A$1,500. Prizes above that amount and up to A$4,000 may be paid out immediately at the retailer's discretion up to six months after the draw date, and amounts over A$4,000 but less than A$25,000 can sometimes be claimed from a retailer too, with authorisation from Oz Lotto's operator Tatts.

Larger prizes can be claimed in person at Tatts' office in Melbourne, and unusually can also be claimed by post by sending the original winning ticket - just be sure to keep a clear copy for your own records. Payments are made by electronic funds transfer or by cheque, and prizes over six months old can still be claimed by special arrangement, with a three-year deadline on tickets bought in the Northern Territory.


Oz Lotto started in February 1994 and was, at the time, the first and only lottery game open to entrants from all areas of Australia. There was an existing Saturday Lotto draw, but New South Wales residents had at that time been unable to enter. The two draws were originally the same, with players needing to match six numbers from 1-45, but in October 2005 the Oz Lotto rules were changed so that a seventh ball was drawn, which must also be matched for a jackpot win.

In November 2012 the uncapped top-level jackpot rolled over to a record-breaking sum of nearly A$112 million, and four winning tickets shared the largest payout on any Australian lottery at that time.

Where to Play

Oz Lotto is played throughout Australia, under the administration of Tatts Group except in Western Australia, where Lotterywest is the regional lottery authority. It originally was Australia's first fully national lottery, as the Saturday Lotto draw was not open to New South Wales residents.

You can also enter from outside of Australia via a lottery courier service, whereby a representative will go to a participating retailer in Australia and buy a ticket on your behalf. If you win, your prize will be paid to you, or for large amounts the ticket will be released to you so you can arrange your prize claim in accordance with the rules.

Oddly enough, even the largest prizes on Oz Lotto can be claimed by post and paid by cheque or electronic funds transfer, meaning there should be no reason in principle why you must travel to Australia to claim even a jackpot win.

Where the Money Goes

Tatts Group, which operates Oz Lotto, has a history of supporting worthy causes, especially including healthcare facilities and children's hospitals. In the 1990s it funded redevelopment work at the Children's Hospital in Melbourne, and it now works with the Starlight Children's Foundation to bring more fun and happiness into the lives of hospitalised young people from early childhood through to teens, with a presence in every children's hospital throughout Australia.


Do I pay tax on my winnings?

There are no local laws to deduct tax from Oz Lotto winnings. If you play by lottery courier from outside of Australia, any local tax laws in your own jurisdiction will also apply.

How long do I have to claim my prize?

The standard claim period is six months; however, it is still possible to claim prizes after this deadline. The procedure to do so depends on where the ticket was bought. There is a fixed three-year deadline on prize claims for Northern Territory tickets.

What was the largest-ever Oz Lotto jackpot?

The largest Oz Lotto jackpot was A$111 million. It was won on the 6th November, 2012 and shared between four lucky winners.

Should I buy a System or Pick ticket?

Both of these options can be confusing at first glance, but once you understand the logic behind them they are quite straightforward, and both are about improving your prize or your chances of winning. Make sure you understand how they will affect your overall ticket price and your odds of making a winning match in any one draw, and then decide if you think either option is right for your style of play.

How old do I need to be to play Oz Lotto?

You must be 18 or over to take part in the Oz Lotto game.
