i second the playgroup idea - my MG has just joined up with the MG before ours who have started a session at a local playgroup.

you can check on the playgroup victoria website & it has details of registered playgroups or i guess you could approach a local one? i went to our centre's open day on saturday & it's awesome - heaps of outdoor area with a cubby house, sandpits, slides & inside lots of different toys & art/craft activity. and they had a petting zoo for open day - i think i had more fun than DS i can't wait to get started! you need to pay a fee to playgroup vic (i think it's $25) and that's your insurance then your centre will have it's own fees.
