Firstly, colours from a landscape perspective. Seventy five percent of Australia is arid and flat, with large areas of red earth. The sky on a cloudless night looks spectacular in the red centre, as there is no light pollution. The beaches are pristine with golden sands, eucalyptus and to a lesser extent wattle trees are ubiquitous in most costal parts of Australia

The horizontal line displayed on the national flags is a metaphor for infrastructure. Roads, rail, electrical grids, water, gas, sewerage and optical fibre are all linier.

Secondly, from a historically perspective.

The history of flags and colours are displayed below
