You are very unlikely to find another Australian who has applied for a WP to Canada. They usually come on IEC visas which are approved almost instantly for Australians, or Australians who become PRs via Express Entry under FSW.
What is your brother's nationality? Is he actually Australian or an Australian PR? That would be the more determining factor than his residency.
And if he is an Australian legal resident, why does he want a WP for Canada? I bet he's taking a pay cut.
