Oz Lotto
Lottery Overview & Statistics
Oz Lotto operates on a 7/47 matrix with two supplementary numbers drawn from the same pool after the seven main numbers. The jackpot odds of 1 in 45,379,620 reflect a single-pool design where supplementary numbers are drawn sequentially without replacement. This structure underpins seven prize divisions, with Divisions 3 through 7 utilising supplementary numbers to expand winning combinations.
Launched in February 1994 as Australia's first national lottery, Oz Lotto is administered by The Lott and draws every Tuesday evening. The jackpot commences at AUD 2 million and rolls over weekly until claimed, with Division 1 prizes structured on a pari-mutuel basis. Record jackpots have surpassed AUD 100 million, including a landmark AUD 111 million draw in January 2013.
The single-pool format with supplementaries creates a mathematically unique profile: supplementary numbers are valid winning numbers for mid-tier divisions but do not contribute to Division 1 eligibility. This design intentionally increases the frequency of Division 3 and 4 wins while concentrating jackpot value.
Game Format & Rules
A standard Oz Lotto entry requires selection of seven numbers from a pool of integers 1 through 47. Following the main draw, two supplementary numbers are drawn sequentially from the remaining 40 numbers in the same barrel. System entries permit selection of 8 to 20 numbers across the main pool, generating all possible seven-number combinations from the chosen set.
Prize eligibility is determined by matching main draw numbers and, for Divisions 3-7, by additionally or alternatively matching supplementary numbers. Division 1 requires matching all seven main numbers with no supplementary involvement. Division 7 (the lowest tier) requires matching one main number plus one supplementary, with odds of approximately 1 in 55.
Ticket sales close at approximately 7:30 PM AEST on Tuesday evenings, with draws conducted at approximately 8:30 PM AEST. Purchasing via an authorised online platform registers the ticket against the official draw database maintained by The Lott.
Prize Structure & Odds Analysis
Oz Lotto's seven prize divisions distribute prize pool allocations as follows: Division 1 (jackpot) receives approximately 20.8% of the prize pool, Division 2 approximately 5%, and Divisions 3 through 7 receive fixed or pari-mutuel allocations covering the remaining pool. Overall any-prize odds stand at approximately 1 in 55.
Division 2 odds (6 main + 1 supplementary) are 1 in 3,241,401, while Division 3 (6 main) carries odds of 1 in 180,078. Division 6 and 7 fixed prizes provide a frequent return floor, with Division 7 (1 main + 1 supplementary) triggering at approximately 1 in 55.
The jackpot commences at AUD 2 million and escalates through rollover accumulation. Pari-mutuel upper divisions may dilute individual prize values significantly when multiple winners share a tier, an important consideration in high-jackpot-draw weeks when ticket volumes increase substantially.
Draw Schedule & Deadlines
Oz Lotto draws are conducted every Tuesday at approximately 8:30 PM AEST (UTC+10), with ticket sales closing at 7:30 PM AEST. Online platform purchases should be finalised before 7:00 PM to allow for processing confirmation against the official ticket database.
Results are published by The Lott immediately after each draw and distributed via official digital channels. Division 1 prize claims must be lodged within six years of the relevant draw date in most Australian jurisdictions.
Annual draw schedules are published by The Lott in advance. Public holiday disruptions are rare; any rescheduled draw dates are communicated through official channels with at least one week's notice.
Cryptocurrency Ticket Purchases
Oz Lotto tickets are purchasable on this platform using Bitcoin, Ethereum, Litecoin, and other supported cryptocurrencies. Transactions are executed at the prevailing market rate at the time of purchase confirmation, with no supplementary conversion fees beyond applicable network costs.
Ticket registrations from crypto purchases are processed identically to fiat-funded entries, with confirmation numbers tied to the official draw database. Prize payments for winning crypto-purchased tickets are disbursed in the player's selected cryptocurrency at the exchange rate applicable at settlement time.
Players should ensure transactions are submitted sufficiently in advance of the 7:30 PM AEST Tuesday cutoff to allow for blockchain confirmation within required timeframes, particularly during periods of elevated network congestion.
