On what special days is it important to fly the Australian flag?

Answer 1

• ANZAC Day (25 April) is arguably the most significant day to fly the Australian flag.
• Australia Day (26 January) is also a patriotic time, commemorating the beginning of European settlement in Australia.
• Remembrance Day (November 11) is another time to fly the flag.

Apart from the above, the Department of the Prime Minister & Cabinet in the Australian Government also advises that there are "days of [national] commemoration on which the flying of the Australian National Flag ... is particularly encouraged", including:

• 1 January - Anniversary of the establishment of the Commonwealth of Australia
• 3 September - Australian National Flag Day
  

Answer 2

Australia's national day would be Australia Day, which is celebrated on 26 January every year. Australia Day celebrates the landing of the First Fleet and the beginning of European occupation of the continent.

Answer 3

Australia does not celebrate a specific flag day. The closest Australia would have to such a thing would be Australia Day, which occurs on 26 January every year. This is a patriotic day when people celebrate what it means to be Australian, so it bears little resemblance to "flag day".
