the stadium was redeveloped after the Olympics to enclose the ends and put a roof on it. it's since been used for club rugby league (virtually empty), rugby test matches, international football matches and they did try afl and 20/20 there as each bottom tier can retract to make the playing surface bigger, but i can't remember the last time any afl was played there. there's been a few concerts there as well.
if you can believe it a couple of years ago there was a plan to flatten it completely and rebuild a 'rectangular' stadium (so only for football/rugby etc) to get fans closer to the action costing around $1.6 billion, this wasn't well received so they then said they'd spend $800 million renovating it instead, which has also been shelved (for now).
i'm heading out there today as there's a massive vaccination centre just down the road from it.
