Does anyone remember this niche Indigenous AFL competition from the mid-2000s?

This has been driving me insane trying to find.

I remember watching an Indigenous footy competition on TV sometime around 2006–09. It may have been on NITV or Fox sports. 

The main thing I remember is that it looked like a heavily modified version of Aussie rules. The best way I can describe it is almost like "half-court AFL". I remember the field being much smaller/shorter than a normal AFL ground and I'm pretty sure the games were short as well.

I originally remembered there only being about 3 teams, although I could definitely be wrong about that. I also vaguely remember team names like "Lightning" and possibly "Eagles", but again, that could be my memory mixing things up.

I've come across the Alice Springs/Ngurratjuta Lightning Carnival while searching and it seems like a possibility, especially since NITV used to broadcast it, but I can't find enough old footage to know if that's actually what I'm remembering.

Does this ring a bell for anyone who watched NITV or Indigenous footy around that time?
