Powerball: The Jackpot Machine

Powerball dominates the record books because its 1-in-134.5-million odds mean Division 1 goes unclaimed far more often. The 2018 format change (from 6/40 to 7/35 + PB/20) made Division 1 even harder, causing more $100M+ prizes. Key milestones: first $100M+ (August 2018), first $150M (September 2019), $200M record (February 2024).

Oz Lotto's Biggest Moments

Oz Lotto's record $112M (November 2012) was shared by four winners. In February 2025, Oz Lotto returned to nine-figure territory at $100M. The May 2022 format change (7/45 → 7/47) means larger jackpots are likely in future.

TattsLotto Superdraws

TattsLotto approaches big prizes through scheduled Superdraw ($20M) and Megadraw ($30M–$40M+) events. These are predictable and TattsLotto's 1-in-8.1M odds make Division 1 far more achievable than Powerball or Oz Lotto.
