I've been playing Friday Night six-pack at the Morphett Vale ICA with mates for about 12 years.
We pay $10 each per game, and registration is approx. $7 or $8 each per season. Not too shabby at all. The way it works is that the highest scoring partnership of the match (match...not for each side) wins for their team a six-pack upstairs in the bar...if you're underage, soft drinks...etc.
We're playing our 1st game of the "new" season tomorrow night, having just played in the Grand Final last Friday...hence she's a pretty full on schedule...unless you have BYES, you'll be playing practically EVERY Friday, bar finals.
ICA's are reasonably flexible with hours of play...so if a mate can't get there until 8.30, you can nominate to play 8.30 or 9.45 games every week. Simple.
