Hi Jane/Bella,
I go to a mothers group all the way over in port stephens. We met through parenting classes that were being run through our child and family health nurse. It might be worth checking with them if there is anything happening in your area. Another thing I can suggest is maybe Gymbaroo or they run Parents as Teachers at Hamilton school (they should be resuming in february). I'm pretty sure they both have websites if you want to look them up.
Mel.
