Australia runs two major national lottery games — OzLotto and Australia Powerball — along with Saturday Lotto and Monday/Wednesday Lotto operated through The Lott. Australian lottery jackpots regularly reach tens of millions of dollars, and the country has some of the highest per-capita lottery participation rates in the world. Here's a complete guide to how Australia's major lottery games work and the best strategies for each.
Australia Powerball: The Biggest Jackpot
Australia Powerball draws every Thursday night. Pick 7 numbers from 1–35 and 1 Powerball from 1–20. The jackpot starts at $3 million AUD and rolls over when not won. Australian Powerball jackpots have reached over $150 million AUD — among the largest lottery prizes ever won in the Southern Hemisphere.

| Division 2 | 7 | 1 in 7,078,443 |
| Division 3 | 6 + Powerball | 1 in 686,176 |

| Division 6 | 4 + Powerball | 1 in 1,173 |
| Division 7 | 5 | 1 in 892 |
| Division 8 | 3 + Powerball | 1 in 188 |

OzLotto: Tuesday Night's Big Game
OzLotto draws every Tuesday. Pick 7 numbers from 1–47. The jackpot starts at $2 million AUD and rolls over when not won, regularly reaching $20–50 million. OzLotto jackpot odds of 1 in 62,891,499 are significantly better than Australia Powerball's 1 in 134M — making it the better choice if maximizing win probability is the priority.
| Division | Match | Odds |
|---|---|---|
| Division 1 | 7/7 | 1 in 62,891,499 |
| Division 2 | 6/7 + 1 Supp | 1 in 3,606,390 |
| Division 3 | 6/7 | 1 in 360,639 |
| Division 4 | 5/7 + 1 Supp | 1 in 29,602 |
| Division 5 | 5/7 | 1 in 3,430 |
| Division 6 | 4/7 | 1 in 154 |
| Division 7 | 3/7 + 1 Supp | 1 in 87 |
Saturday Lotto & Monday/Wednesday Lotto
Saturday Lotto (also called Gold Lotto or Tattslotto depending on the state) is Australia's oldest and most popular lottery, drawing every Saturday. Pick 6 numbers from 1–45. The jackpot starts at $4 million AUD with odds of 1 in 8,145,060 — significantly better than either Powerball or OzLotto. Monday Lotto and Wednesday Lotto follow the same 6/45 format with smaller jackpots but the same odds.
Australia Powerball vs. OzLotto: Which to Play?
OzLotto has better jackpot odds (1 in 62.9M vs 1 in 134.5M) but typically smaller jackpots. Australia Powerball's jackpots can reach $100M+ during long rollover streaks. Saturday Lotto has by far the best odds (1 in 8.1M) for a meaningful jackpot. The best strategy: play Saturday Lotto for consistent shot at a reasonable prize, and play OzLotto/Powerball when jackpots are large.
Strategy 1: 7-Ball Distribution (Powerball & OzLotto)
Both Australia Powerball (1–35) and OzLotto (1–47) require 7 main numbers. For Powerball's compressed 1–35 range, spread picks across five 7-number ranges: 1–7, 8–14, 15–21, 22–28, 29–35. For OzLotto's wider 1–47 range, aim for coverage across: 1–10, 11–20, 21–30, 31–40, 41–47.
Strategy 2: Powerball Number Selection (1–20)
The Australia Powerball number ranges from 1–20. With only 20 options, frequency analysis is particularly meaningful. Historically, Powerballs in the mid-range (7–14) have appeared with slightly above-average frequency, while numbers at the extremes (1–3 and 18–20) are underrepresented in winning draws.
Strategy 3: Supplementary Numbers (OzLotto)
OzLotto draws 2 supplementary numbers after the 7 main balls. Matching your picks against the supplementaries triggers Division 2 and Division 4 prizes. There's no way to explicitly pick for the supps since they come from the remaining pool — but a distribution strategy that leaves more "available" numbers in a specific range can slightly increase your supp coverage.
