Hi ,my son goes to cubs ,its $6
pr night( every monday ) plus insurance which i think is a couple of hundred dollars for the year.He loves it especially the camps that average around$50 a time,all in all pretty cheap for the enjoyment and education they get.
My daughter attends kindy-gymnastics which is an hour week at $10 per lesson ,at 4 she is climbing the flexi ladder and walking the beam she really enjoys it and it keeps her fit too,lol(as well as tires her out,lol).
Theres also ,football,soccer,singing,dancing,rugby,brownies,ar my cadets,tennis,netball,swimming and karate type classes ,pony clubs,the list is endless ,all in our susburb and you should find most suburbs offer similar classes,,i wouldnt worry about activities too much ,theres more available than the kids could possibly participate in!!lol
