What is the meaning of the Australian flag?

Answer 1

The parts of the Australian National Flag mean the following:

The Union Jack in the upper left corner (or canton) acknowledges Australia's origin as a British settlement.

The Southern Cross, positioned on the right hand side of the flag, is a constellation visible from all of Australia's states and territories, and which was vital to early ships' navigation, and which represents Australia's position in the Southern Hemisphere.

In the bottom left hand corner is the Federation Star, also known as the Commonwealth Star, a seven pointed star which represents the union of the six colonies at federation. There is a seventh point to represent Australia's many territories (mainland and offshore).

These symbols are on a British blue ensign.

Answer 2

The Union Jack is on the Australian flag because it reflects our major heritage. The big star is the Commonwealth star which has seven points, one for each state and one for the territories. The Southern Cross is a constellation that is visible from anywhere in Australia.
