Target Australia has AFL Evolution for $75 on both Xbox One and PS4. All you need to do is head to their eBay store, use the code C5OZ and you can click and collect to pickup the game in-store.
This is the cheapest copy of the game so far, and judging by usual AFL/NRL game pricing, there’s usually a cheap introductory price and then it never really drops below $90-100.
You can find the Xbox One version HERE and PS4 version HERE.
