For us Auskick is $10 for the season, Junior AFL (8-12) is 60. We don't have enough to play an Auskick game every weekend though & kids are usually on the field with the juniors from about 6 to make up the numbers.
They all get the same amount at training. Do a few drills together, then break up into the 2 groups & do separate drills.

DD even joined in last season for fun at 3. She loves it. Netta (Net Set Go) is a little more strict here though. She was allowed to go to AASC & do all the fun drills, but no games.

Either way both she & DS have been involved in sports from around 4 & they really enjoy it. We've got great people coaching here too, which makes it all what it is. DD1 is showing some talent in netball & plans to continue through high school & I was told that at all of 4 DS was already showing some talent I don't know if they'll go far, but the life skills they're all picking up along the way are well worth it.
