Cycling Clubs & Groups: Looking for riding partners in Berwick, Victoria, Australia

I am a weekend rider looking for riding partners in my area.  I am an intermediate level rider - I average around 25km and hour.  Not great on big hills but usually get up them eventually!  I normally do between 40-70kms and head out on the quite roads towards Cardinia, Koo Wee Rup and Drouin.
