Aussie wanting to follow Aus teams in HSC, where can I find fixtures/details?

Hello, I’m struggling to find many details or fixtures of the Halo Championship. I’m a bit new to Halo e-Sports. Is there a national Aus team? Or is it made up of a bunch of different teams representing Australia? And is it a global competition, or just the different regions battling it out? When is the next AUS fixture?
Thanks.

Have a look around here (on the Halo Waypoint website. Don’t know whether anything on there will help though.
