Expat Moms or Australians who have lived overseas in Brisbane with primary school kids ?

I have two kids in primary school with a husband who works longs hours and travels sometime. I do work part time but would love to meet new people and hopeful to make new friends. We moved here to Brisbane a few years ago.... Any expat partners/wives? Any Australians who used to live overseas or interstate? Any moms who have no family support... Cheers Dee
