Oz Lotto Explained: Odds, Numbers, Prizes & How the Australian Lottery Works

Oz Lotto is an Australian jackpot lottery where players choose seven numbers from 1 to 47, with Division One odds of approximately 1 in 62.9 million.

Drawn every Tuesday, Oz Lotto is known for producing multimillion-dollar jackpots while using a relatively simple number format.

But there is more to the game than matching seven numbers.

Oz Lotto has seven prize divisions, three supplementary numbers are drawn to help determine some of the lower prize divisions, and you can win without matching all seven winning numbers.

So how exactly does Oz Lotto work, what are your real chances of winning, and how does it compare with Australia's other famous jackpot game, Powerball?

Here is the simple MagicLotto guide.

How Does Oz Lotto Work?

A standard Oz Lotto entry consists of seven numbers selected from 1 to 47.

During the official draw, 10 balls are drawn from the 47-ball pool.

• The first seven balls are the winning numbers.
• The next three balls are supplementary numbers.

To win Division One — the jackpot — all seven numbers on one standard entry need to match the seven winning numbers.

The supplementary numbers are used when determining several of the game's lower prize divisions.

MagicLotto customers can play Oz Lotto online through MagicLotto for available Tuesday draws.

What Are the Odds of Winning the Oz Lotto Jackpot?

The official Division One odds for one standard Oz Lotto game are:

1 in 62,891,499

That means there are almost 63 million possible combinations of seven numbers from the 47-number pool.

Those are very long odds, and winning the jackpot should never be expected.

However, Oz Lotto's Division One odds are notably different from Australia's Powerball, where the official Division One odds are approximately 1 in 134.5 million.

Why Are the Oz Lotto Odds 1 in 62,891,499?

Oz Lotto's jackpot probability comes directly from the number of ways seven numbers can be selected from a pool of 47 without regard to order.

The calculation produces:

62,891,499 possible seven-number combinations

Only one of those combinations will contain all seven winning numbers in a particular draw.

Do You Need All Seven Numbers to Win Oz Lotto?

No.

Matching all seven winning numbers is required for Division One, but Oz Lotto has seven prize divisions.

The official winning combinations are:

So while seven correct numbers are required for the jackpot, a prize can be won with as few as three winning numbers plus one supplementary number.

What Are the Overall Odds of Winning an Oz Lotto Prize?

There is an important difference between the odds of winning the jackpot and the odds of winning any prize.

Division One odds are approximately:

1 in 62,891,499

But the official overall odds of winning any Oz Lotto prize with one standard game are approximately:

1 in 51

This does not mean that buying 51 entries guarantees a prize.

Each entry remains an independent game of chance, so actual results can vary enormously.

What Are Oz Lotto Supplementary Numbers?

Three supplementary numbers are drawn after the seven main winning numbers.

They do not replace the main numbers and cannot help an entry win Division One.

Instead, supplementary numbers help determine certain lower prize categories.

For example, matching six main winning numbers plus at least one supplementary number qualifies for Division Two, while matching three main winning numbers plus at least one supplementary number qualifies for Division Seven.

When Is Oz Lotto Drawn?

Oz Lotto is drawn every Tuesday night in Australia.

For South African players, the exact MagicLotto entry deadline should always be checked on the current Oz Lotto entry page, because entries must be processed before the applicable official draw cut-off.

After the draw, you can view the latest Oz Lotto winning numbers and prize results on MagicLotto.

Why Can Oz Lotto Jackpots Become So Large?

Oz Lotto is a jackpotting lottery.

If nobody matches all seven winning numbers in a draw, the Division One jackpot can roll over into the following week's draw in accordance with the official game rules.

Repeated rollovers can cause the advertised jackpot to grow substantially.

Oz Lotto's base Division One offer starts at AU$3 million, but jackpot runs have produced prizes worth tens of millions of Australian dollars and, on exceptional occasions, much more.

What Happens If More Than One Person Wins the Oz Lotto Jackpot?

A large advertised jackpot does not necessarily mean one person will receive the entire amount.

If multiple valid entries match all seven winning numbers, the Division One prize is shared between those winning entries according to the official rules.

A recent example came in August 2026, when two winning entries shared an AU$40 million Oz Lotto Division One prize, resulting in AU$20 million for each winning entry.

It is a useful reminder that the advertised jackpot represents the Division One prize pool rather than a guaranteed payment to a single winner.

Does a Bigger Oz Lotto Jackpot Improve Your Odds?

No.

Whether the advertised jackpot is AU$3 million, AU$20 million or much larger, the standard number matrix remains seven numbers from 47.

That means the probability of one standard entry matching all seven winning numbers remains approximately 1 in 62,891,499.

A bigger jackpot changes the potential prize, not the mathematical probability of your selected combination being drawn.

Are Some Oz Lotto Numbers More Likely to Win?

No valid seven-number combination has a mathematical advantage over another in an independent fair draw.

Players sometimes look at historical results to identify numbers that have appeared frequently or numbers that have not appeared for some time.

These are commonly called hot numbers and cold numbers.

Historical frequency can be interesting to analyse, but it does not change the probability of a number being selected in the next independent draw.

You can explore recent statistics through the MagicLotto Hot & Cold Numbers tool.

Is Quick Pick Better Than Choosing Your Own Oz Lotto Numbers?

No.

A randomly generated valid combination has exactly the same mathematical probability of winning as a combination you choose yourself.

Quick Pick is simply a convenient option for players who prefer not to select seven numbers manually.

Likewise, birthdays, favourite numbers and previous winning numbers do not make a combination inherently more or less likely to appear.

Oz Lotto vs Australia Powerball: What's the Difference?

Oz Lotto and Australia Powerball are two separate Australian jackpot lotteries.

Oz Lotto uses a single main number pool: you select seven numbers from 1 to 47.

Australia Powerball uses main numbers plus a separate Powerball number, giving it a different structure and different Division One odds.

Official Division One odds are approximately:

• Oz Lotto: 1 in 62,891,499
• Australia Powerball: 1 in 134,490,400

This means Oz Lotto has the shorter Division One odds of the two, although both remain extremely difficult jackpots to win.

MagicLotto customers can browse Oz Lotto, Australia Powerball and other international lotteries from the main lottery selection.

Are Oz Lotto Winnings Taxed?

Australian lottery prizes are generally paid to winners without Australian income tax being deducted from the prize itself.

However, tax circumstances can differ depending on where a player lives, where the official ticket is purchased and what happens to the money after it is received.

For example, income subsequently earned by investing lottery winnings can have different tax consequences from the original prize.

South African players can read the MagicLotto Lottery Tax Guide for general information.

Large winners should obtain professional tax advice relevant to their own circumstances.
