Oz Lotto Australia: The Ultimate Guide
Your Tuesday night ritual for big wins.
What is Oz Lotto?
Oz Lotto was Australia's first truly national lottery game. It launched in 1994 and has since become famous for its "Big Aussie Luck" brand. Originally, it required 6 numbers, but in 2005, it changed to 7 numbers to create even larger jackpots.
How to Play
To play Oz Lotto, you must choose 7 numbers from a single pool of 1 to 47. During the draw, 7 winning numbers and 3 supplementary numbers are selected at random.
System Entries
Many Oz Lotto players use "System Entries" to increase their chances. A System 8 entry, for example, allows you to pick 8 numbers, covering every 7-number combination within that set.
Draw Times
Oz Lotto draws take place every Tuesday night at 8:30 PM AEST/AEDT. It is often referred to as "Tuesday's Big One."
