Understanding Oz Lotto Drawings and Prize Structure

The Australian lottery, commonly referred to as Oz Lotto, is one of the most popular lotteries in Australia. The game offers a significant prize pool, with the top jackpot often reaching millions of dollars. However, understanding how the drawings work and what the chances are for winning can be confusing for some players.

How Drawings Work

Oz Lotto has six main numbers between 1 and 45, along with two supplementary numbers between 1 and 45. Players choose their own numbers or use a random number generator to select them. The game is drawn Oz Lotto casino every Tuesday night at 8:30 pm Australian Eastern Standard Time (AEST). During the drawing, balls are randomly selected from the main and supplementary pools using a ball-drawing machine.

The numbers are then displayed on screens across Australia, with results also being made available online through various websites and mobile apps. Winning combinations are determined by matching the drawn numbers to those chosen by players.

Types of Winners

There are several types of winners in Oz Lotto:

  • Division 1: The jackpot winner(s) who match all six main numbers and both supplementary numbers correctly.
  • Division 2: Players who match five main numbers with one supplementary number or six main numbers without the two correct supplementary numbers.
  • Division 3: Winners who match four main numbers with either of the correct supplementary numbers or any three main numbers plus both supplementary numbers.
  • Division 4: Players who match four main numbers and one correct supplementary number, excluding the case above.

Prize Structure

The Oz Lotto prize structure is based on a percentage of ticket sales. The top prize (Division 1) has a set minimum guarantee, which increases by $2 million every time the jackpot remains unclaimed for two consecutive drawings. This ensures that the top prize always exceeds $5 million.
