Overdue Numbers
The table below presents key metrics for analyzing overdue numbers. It includes columns for Maximum Interval, Average Interval, and Last Draw Interval, which indicate the longest gap, the average gap, and the number of draws since a number last appeared, respectively. The chart covers 75 draws, from Jul. 2, 2024 to Dec. 2, 2025 .
Two additional columns, Average Rating and Maximum Rating, offer deeper insights into recent trends. The Average Rating is calculated by dividing the last draw interval by the average interval, showing how the most recent gap compares to typical spacing. Similarly, the Maximum Rating is obtained by dividing the last draw interval by the maximum interval, providing a measure of how close the current interval is to the longest ever recorded. Together, these statistics help identify numbers that may be overdue or performing unusually based on historical patterns.
To identify lottery numbers that may be overdue, attention should be given to the column Last Draw Interval, Average Rating, and Maximum Rating. A higher Last Draw Interval value indicates that the number hasn’t been drawn in a while and could be considered overdue. If the Average Rating is greater than 1, especially significantly so, it suggests the number has gone longer than usual without being drawn. Meanwhile, a Maximum Rating value close to 1 implies that the number is nearing or exceeding its historical maximum gap, reinforcing the idea that it may be overdue. Therefore, numbers with a high last draw interval, an average rating well above 1, and a maximum rating nearing 1 are likely candidates for being considered overdue.

Format Changes in Australia's Oz Lotto
Oz Lotto, Australia’s first national lottery, has undergone several format changes since its launch in 1994. Below is the timeline of the Australia's Oz lotto format changes:
| Period | Format | Supplementary Nos. |
|---|---|---|
| 1994 - Oct. 11, 2005 | 6 numbers from a pool of 45 (6/45) | 2 numbers from the same pool. |
| Oct. 18, 2005 - May 10, 2022 | 7 numbers from a pool of 45 (7/45) | 2 number from the same pool. |
| May 17, 2022 - Present | 7 numbers from a pool of 47 (7/47) | 3 number from the same pool |
Initially, the game required players to select six numbers from a pool of 45, and two supplementary numbers were drawn to help determine secondary prizes. In October 2005, the format was modified to increase the number of main numbers drawn from six to seven, still from a pool of 45, while retaining two supplementary numbers. This change made the jackpot more difficult to win but allowed for larger prize pools. In May 2022, Oz Lotto underwent another significant update. The number pool was increased from 45 to 47, while the game continued to draw seven main numbers. Additionally, the number of supplementary numbers increased from two to three. Along with this change, the minimum jackpot prize was raised from $2 million to $3 million, and the overall odds of winning any prize improved, creating more opportunities for players to win across additional prize divisions. These changes reflect Oz Lotto's ongoing efforts to remain engaging and competitive within Australia’s lottery landscape.
How Australia's Oz Lotto Format Changes Affect Your Number Strategy.
These format changes have a direct impact on statistical analysis. Mixing frequency data across different formats is not advisable because each version of the game has a different number pool and probability structure.
For example, a number that appeared frequently in the 6/45 format may have done so due to higher individual draw probability, but that same frequency can be misleading in the 7/45 or 7/47 formats. Furthermore, changes to the number pool also significantly affect how often a specific supplementary numbers appear.
Therefore, for meaningful analysis, it’s essential to treat each format as its own distinct dataset. Analyzing trends or frequencies should be restricted to results from within the same format period, especially if the goal is to inform number selection in the current game structure.
