They certainly do - the RAAF roundel is a variant on the traditional one of the (British) Royal Air Force.

I had a hunch that they did but I wasn't certain.I know Canadian military aircraft sport the maple leaf,which is basically their national symbol.A few years back I was surprised to see several Canadian fighter jets at a US Air Force air show near me.I asked the pilot why they were there and he laughed and said "oh,we routinely appear at your air shows and your aircraft routinely appears at ours".

Many years ago, a Vulcan bomber, with a Rhodesian crew, flew from SAC at Omaha to an airshow in Des Moines. The pilot overshot the runway and had to go around for a second landing. I watched from our back yard as the big bat wing airplane circled downtown and came in over our house.
Very cool.

Yes - Canada, Australia, and New Zealand, all have roundels based on that of the Royal Air Force, differenced in the middle by a specific national symbol.

Canada came up with the idea first, but a good idea is a good idea - tradition should matter to a good military. Never been quite sure about New Zealand's choice of a flightless bird though - I'd have gone with something based on the silver fern (and they did trial that).
