While I'm not really one for celebrating religion based holidays amd the like, Indo have a couple of "traditions" among our circle of friends which revolve around sporting events.
The main one is AFL Grand Final day where we all go around to @dahmsy79's house for a BBQ and to watch the game. I run a sweep on a couple of different match-based outcomes and we all generally have a great day. The evolution of this day has been interesting over the past decade, from a get together with a heavy focus on drinking and partying, to what is now very much a family day as we have nearly all settled down and have children.
Haha... definitely am Australian (well... in some states...) tradition! For us (well, more my wife's side), it was more the rugby... and more the NSW vs QLD matchup which was the big game day. ... but it is great that you've continued the tradition through having kids, so that all the different generations of family friends get to meet up on a BBQ!
