With a Second Division kicking off next year, I believe the time is ripe for Football to embrace the concept of an Inter State/Territory Cup based on the existing Federations.

This year it could be run in the later half of the year, with two knockout phases.

Phase 1 - two games (Game A and B) drawn from a hat, first out gets home advantage, winners progress. Losers play off for final spot

Northern NSW
Northern Territory
Tasmania
Western Australia

Phase 2: Knock out, two rounds and final

Australian Capital Territory
New South Wales
Queensland
South Australia
Victoria
Winner Game A
Winner Game B
Best Loser

In 2024 this could become a whole of year series, both Mens and Womens. It may even be worthwhile from a developmental perspective to have younger age groups participate. There are enough International windows to have a full series.

The 2024 draw would be an "event" made for TV/streaming, with the first team drawn being the home team. In later parts of the draw, this may not work out as the idea would be to have 4 home and 4 away games each year. In 2025 the home team would reverse and so on.
