The black symbolises the first nations peoples, as the land will firstly, and always belong to them. The gold arrow points forward to the future, the golden yellow sands of our coast, and fields, as well as the wealth of our country. The shape is also representative of a boomerang. The background is a deep blue, like the ocean and sky surrounding us, as well as a visual echo to the current flag. The Commonwealth star symbolises our federation and modern nation, striving for unity and progress ever upward.
I wanted my design to echo the current flags but not be too much of a mashup of any of them, retaining simple and strong motifs and values of each.
