Hi, mount martha, mornington, mt eliza or frankston south all nice areas. some have roads you would want to avoid living near just like in uk. but great areas for schools, shops, commuting, beach and making friends. we came out a year ago with 3 children similar ages, have settled in mount martha they love it, near the beach lots of parks, and lots going on.
good luck with your decision, i know its a hard one as it makes such a difference where you go to start with!
