No they dont share the same flag or fall under the queen on england like Aus and NZ..
But yes Dubai is in India and canadians and mexicans are part of North America.
They don't have the same flag. Like i already said, it is similar, but different.
When the queen dies, Australia will become a republic. The queen has no power in Australia as it is anyway.
To say Aus and NZ is the same country is disrespectful. Yes, we are very similar, but we are both established, seperate countires.
