Aus. Saturday Lotto
Australia's Saturday Lotto has run since 1974. Tatts Group, licensed by state regulators across Australia, operates the draw. The game generates revenue for state and territory lotteries, with funds directed to public causes and community grants.
How the Draw Works
Saturday Lotto uses a 45-ball drum system. Players select 6 numbers from 1 to 45. The draw machine selects 6 winning numbers, then 2 supplementary numbers from the remaining balls.
This structure creates seven distinct prize divisions. The first four divisions require matches from the six main numbers only. Divisions 5, 6, and 7 incorporate the supplementary balls, expanding the ways players can win without matching the full main set.
The draw happens on Saturday evening. Results post immediately after the mechanical draw completes. Verification and validation happen before official publication.
Prize Structure and Odds
Division 1 requires all six main numbers. This is the jackpot tier. The odds of winning Division 1 are 1 in 8,145,060. The prize amount varies based on ticket sales and contributions to that division's pool.
Division 2 hits when five main numbers plus one supplementary number match. Division 3 needs five main numbers only. Division 4 requires four main numbers. These three tiers share a fixed prize percentage from the total pool.
Divisions 5, 6, and 7 are guaranteed fixed amounts. Division 5 pays for three main numbers plus two supplementary balls. Division 6 awards a fixed sum for three main numbers. Division 7 returns the entry cost for two main numbers plus one supplementary ball.
Overall odds of winning any prize in Saturday Lotto sit at approximately 1 in 87. This accounts for all seven divisions combined. The structure ensures many tickets win something, though most returns are small relative to ticket cost.
Draw Timing and Schedule
The draw happens every Saturday night. Draw time varies by state but typically occurs between 8 PM and 10 PM Australian Eastern time. The exact time remains consistent each week.
Ticket sales close before the draw. Entry cutoff times differ by state and sales channel. Online platforms close sales at their specified deadline, usually 30 minutes before draw time.
Results publish within minutes of the draw conclusion. Major winners are verified before public announcement. Unclaimed prizes roll to Division 1 the following week, increasing the jackpot pool.
Odds and Expected Value
The expected value of a Saturday Lotto ticket is negative. Players pay $1 per entry. The total returned to winners averages around 40-45 cents per dollar wagered, depending on the specific draw and division distribution.
This payout rate includes all seven divisions. Large Division 1 winners receive the majority of media attention, but the bulk of tickets win Division 7 (two main numbers plus one supplementary) or win nothing at all.
Syndicates don't improve mathematical odds, but they do reduce individual cost per combination. A ten-person syndicate buying 100 tickets collectively spreads the $100 cost ten ways. Each member still faces the same odds of any single combination winning, but their fractional stake reduces the jackpot fraction each person receives if they win.
Mathematically, Saturday Lotto is a consumption product, not an investment. The house edge is steep. Regular play over time produces a guaranteed net loss for the player.
Tax Treatment in Australia
Australian residents pay no income tax on lottery prizes, regardless of prize size. This differs from many other jurisdictions where large wins trigger taxation.
Tatts Group withholds no tax from Saturday Lotto payouts. Winners receive the full advertised amount. Overseas residents may face different tax implications in their home country depending on local law, but within Australia, lottery winnings remain tax-free.
This tax-free status applies to all seven divisions. A Division 1 jackpot or a Division 7 fixed return both avoid income tax assessment. Administrative fees or legal costs associated with claiming large prizes remain the responsibility of the winner.
Frequently Asked Questions
What is the difference between the main numbers and supplementary balls?
The draw machine selects 6 main numbers first, then draws 2 supplementary numbers from the remaining 39 balls. Divisions 1 to 4 depend only on matching the 6 main numbers. Divisions 5, 6, and 7 require matches involving one or both supplementary balls, creating additional winning combinations below the top tiers.
How often does Saturday Lotto draw?
Saturday Lotto draws once per week, every Saturday night. The draw time is consistent but varies by state. Ticket sales close approximately 30 minutes before the draw commences. Results post within minutes after the draw concludes.
What are my odds of winning any prize?
Approximately 1 in 87. This includes all seven prize divisions combined. However, most wins fall into Division 7 or Division 6, which return small fixed amounts. The odds of Division 1 (the jackpot) are 1 in 8,145,060.
Do I pay tax on Saturday Lotto winnings in Australia?
No. Australian residents receive lottery winnings tax-free, regardless of prize amount. Tatts Group does not withhold tax from payouts. Overseas residents should verify their own jurisdiction's tax laws, as they may face liability in their home country.
How does a syndicate affect my chances in Saturday Lotto?
A syndicate doesn't improve the mathematical odds of any single combination winning. It distributes cost and prize across multiple players. A syndicate buying 100 tickets has the same probability of a jackpot win as any individual holding one of those 100 tickets, but the prize is split accordingly.
What happens if no one wins Division 1?
Unclaimed Division 1 prize money rolls over to the following Saturday's Division 1 pool, increasing the jackpot. This continues until someone matches all six main numbers. Division 2 through 7 have fixed or percentage-based allocations that reset each week.
