Regardless of debates over Australian cultural identity, the flag and a potential republic, the ‘Green and Gold’ colours of our national sporting teams are recognised worldwide. The Golden Wattle (Acacia pycnantha), from which these colours are derived, was first proposed as a national flower in the 1880s during the prelude to Federation. However, it was not until the 1988 Bicentenary Celebrations that it was formally declared as Australia’s floral emblem. Why was the wattle chosen for this honour over its main competitor, the spectacular red waratah? And what was the significance of using wattle as a symbol of national unity and mourning in the wake of the 2002 Bali bombings?
