Here are some niche ideas with Facebook targeting parameters called 'Receipts' http://blog.dropwow.com/receipts/
Concerning suppliers in Australia, I may offer China-based vendors (not from Australia) that can dropship to Australia as I represent Dropwow dropshipping marketplace (https://apps.shopify.com/dropwow).
Hope niche ideas will be helpful.
