Tuesday night is draw night in Australia. This guide covers the 7-from-45 format, all seven prize divisions, system entries, and what our generator above produces for your quick pick.
Oz Lotto (also called Oz Lotto or simply "Oz") is Australia's original national lottery game, launched in February 1994. It was the first fully national lottery draw on the continent.
Pick 7 numbers from 1 to 45. The draw also produces 2 supplementary numbers that do not count toward the jackpot but improve lower-division wins.
Draws run every Tuesday at approximately 8:30 PM AEST/AEDT. A standard minimum entry costs around $1.30 per game (prices vary slightly by retailer and entry type).
System entries let you pick 8 to 20 numbers and play every possible seven-number combination. A System 8 generates 8 games, System 9 generates 36 games, and so on. Cost scales with the number of combinations.
Retailers and online platforms sell syndicate shares where a group pools entries and splits winnings proportionally.

Division 1 jackpots start around $2 million and roll over when unwon. Several Australian jackpots have exceeded $100 million during long rollover sequences.
Oz Lotto Division 1 odds (1 in 45,379,620) are similar to UK Lotto and better than US Powerball or Mega Millions. The trade-off is a single weekly draw instead of two or three per week.
