Australia
Lucky Australian Powerball, Oz Lotto and Saturday Lotto numbers
Australia's three main draws. Note that Australian Powerball is a completely different game from the American one despite the name, seven numbers from 35 rather than five from 69, and Oz Lotto's pool grew from 45 to 47 in 2022, which roughly doubled the odds against it.
Numbers built from your chart, not a shuffle
Any site can pick random numbers. Weighting the pool by your own Day Master, Life Path and Lo Shu grid needs your birth moment.
The formats, side by side
| Game | Numbers drawn | Second pool | Jackpot odds |
|---|---|---|---|
| Australian Powerball | 7 of 1–35 | 1 of 1–20 (Powerball) | 1 in 134,490,400 |

| Saturday Lotto | 6 of 1–45 | — | 1 in 8,145,060 |
Australian Powerball
Seven main numbers from 35 plus a Powerball from 20, a different game from the American Powerball despite the name, and drawn from a much smaller pool. There are 6,724,520 ways to fill the 7 main numbers, and each must also land the right Powerball, one of 20 possibilities, from a separate pool, which multiplies out to the 1 in 134,490,400.
Oz Lotto
Seven from 47. The pool grew from 45 to 47 in May 2022, which roughly doubled the odds against a jackpot. There are 62,891,499 ways to choose 7 numbers from 47, and a line covers exactly one of them, which is the whole arithmetic behind the 1 in 62,891,499.
Saturday Lotto
Six from 45, the long-running Saturday draw. Sold as Tattslotto, Gold Lotto or X Lotto depending on the state; the game is the same. There are 8,145,060 ways to choose 6 numbers from 45, and a line covers exactly one of them, which is the whole arithmetic behind the 1 in 8,145,060.

Other draws you can read this way
Same birth data, a different pool to fit it to. There is also every lucky-number calculator.
Picking above 31
This is not a system and it will not shorten your odds by any amount. It is about crowding. Some numbers are held by far more tickets than others, and that decides what a jackpot is divided by rather than who wins it.
Australian Powerball
4 of the 35 numbers on a Australian Powerball form are above 31, which puts them outside every birthday, anniversary and door number in play. Dates cannot reach past 31, so every line built from one crowds into the same stretch of the board. Lines built entirely from calendar numbers make up 39.1 per cent of the possible lines, and a far larger share of the tickets people fill in by hand. A line reaching above 31 wins no more often. It is held by fewer people when it does. The Powerball pool stops at 20, so that one sits inside calendar range whatever you do with the main numbers.
Oz Lotto
Only 66 per cent of the Oz Lotto pool falls inside calendar range: 31 numbers a date could give you, 16 it cannot. Hand-picked lines lean on that smaller half, because birthdays, anniversaries and house numbers all stop at 31. Lines built entirely from calendar numbers make up 4.2 per cent of the possible lines, and a far larger share of the tickets people fill in by hand. Nothing up there is more likely to be drawn. Rather less of the country is waiting on it.
Saturday Lotto
Of the 45 main numbers in Saturday Lotto, 31 could be a day of the month and 14 could not. Birthdays, anniversaries and door numbers all run out at 31, and hand-filled slips cluster there accordingly. Lines built entirely from calendar numbers make up 9.0 per cent of the possible lines, and a far larger share of the tickets people fill in by hand. Going above 31 buys you no extra chance at all. It buys you fewer people to share with.
Figures computed from each game's own format. The calculator above weights your pool by your chart rather than by this, and neither approach makes a draw more predictable than it is.
Syndicates and the Saturday habit
Australian Powerball draws seven main numbers from a pool of only 35, which reads like generous odds until the Powerball from 20 is multiplied in. Oz Lotto also takes seven, from 47. Saturday Lotto is the old 6/45, and it is the one with the weekly-ritual attached rather than the jackpot-chasing.
Syndicate play is more normal here than in most markets, through workplaces and pubs and the operators' own share systems. It is the only strategy on this page with an arithmetic case behind it: a syndicate does not change any single line's odds, it just buys more lines for your money and cuts the payout by the same factor. What it buys is a better chance of a small return and no chance at all of a whole jackpot.
