Aus. Mon & Wed Lotto

How the Game Works

Aus. Mon & Wed Lotto requires you to select 6 numbers from a pool of 1 to 45. Each Monday and Wednesday draw, the lottery draws 6 winning numbers plus 2 supplementary numbers.

The 6 main numbers determine the primary prize divisions. The 2 supplementary numbers create additional division pathways, allowing tickets to win prizes with partial matches combined with a supplementary ball.

You must match all 6 numbers to win Division 1 (the jackpot). Matching 5 main numbers plus 1 supplementary wins Division 2. Five main numbers alone wins Division 3. The structure continues downward, with Division 6 requiring 3 numbers.

Draws occur at 8:30 PM AEST on both Monday and Wednesday. Results are published immediately after the draw closes.

Prize Division Breakdown

Aus. Mon & Wed Lotto uses a pari-mutuel system for most divisions. This means the total prize pool is shared among winners in each division. Division 1 (jackpot) rolls over to the next draw if no one wins.

Division 1 requires all 6 numbers. This is the rarest outcome. Division 2 needs 5 numbers plus 1 supplementary ball. Division 3 is 5 numbers only. Division 4 is 4 numbers plus 1 supplementary. Division 5 is 4 numbers. Division 6 is 3 numbers plus 1 supplementary, or 3 numbers plus 2 supplementaries, depending on state variations.

Lower divisions have fixed prize amounts in some cases, while upper divisions depend on ticket sales and the number of winners. Prize pool distribution typically allocates roughly 50% of revenue back to prizes, with the remainder split between operator, retailer commissions, and taxation.

Exact odds for each division depend on the mathematical combination of 45 numbers taken 6 at a time, plus the supplementary mechanics. The overall odds of winning any prize sit around 1 in 87.

History and Regulation

Aus. Mon & Wed Lotto has operated since the 1970s as a core national lottery product in Australia. The lottery is run by Lotteries Australia, a consortium operating under state-based licenses. Each Australian state and territory grants regulatory oversight to its own lotteries commission or equivalent body.

This decentralized structure means licensing conditions vary slightly by jurisdiction, though the core game mechanics remain uniform across all states. The scheme is audited annually to ensure compliance with gaming laws and player protection standards.

Draw Schedule and Timing

Draws take place every Monday at 8:30 PM AEST and every Wednesday at 8:30 PM AEST. These times are fixed and do not vary for public holidays or special events. Entry closes approximately 30 minutes before the draw time, though retailers and online platforms may set earlier cutoffs.

Results are published online within minutes of the draw closing. Retailers receive results within the hour. Prize claim periods are set by state regulation, typically allowing 6 months from the draw date to claim winnings, though most winners claim within days or weeks.

Odds, Expected Value, and Syndicate Math

The overall odds of winning any prize in Aus. Mon & Wed Lotto are approximately 1 in 87. This figure combines all 6 divisions and represents the likelihood of matching at least the minimum requirement (3 numbers for Division 6).

Odds for Division 1 are roughly 1 in 8.1 million. These are the product of combinations: 45 choose 6 equals 8,145,060.

Expected value (EV) in a lottery is the average return per dollar wagered. In Aus. Mon & Wed Lotto, the pari-mutuel structure means EV is negative for players. Roughly 45-50 cents of every dollar returns to winners. The remainder funds operations, state revenue, and retail margins. Over many tickets, you expect to lose money.

Syndicates reduce the cost per entry and increase your odds of any prize proportionally, but do not improve the underlying negative EV. A 10-person syndicate shares ticket costs ten ways, so your odds of sharing a Division 1 prize become ten times higher (from your perspective), but your stake is also one-tenth. The mathematics of shared wins assumes equal splitting agreements and no disputes among members.

Tax Treatment in Australia

Lottery winnings in Australia are generally not subject to income tax. The Australian Tax Office (ATO) considers lottery prizes to be windfalls from games of chance, not assessable income. This applies across all states.

Prize money is received tax-free, regardless of amount. However, state-based duties or levies on tickets themselves are factored into the ticket price before purchase.

If you reinvest winnings into other ventures or income-producing assets, subsequent gains from those assets may be taxable. Only the original lottery prize itself carries no tax obligation.
