Flags of Australia and Oceania
This continent is combining a mainland, wholly occupied by the country of Australia, with the lot of island nations of Oceania whose names are less known. Some of them are the former and present British territories, that's why on their flags we can see the Union Jack in the up left corner.
The most recognized national flags in this region are the Australian Southern Cross and New Zealand's Southern Cross, called so by the name of constellation represented on them.
