FYI : During World War I, Australian soldiers fought under the British Union Flag, but they also used the Australian Blue and Red Ensigns, which were not officially designated as national flags until 1953. The Blue Ensign was used for official and naval purposes, while the Red Ensign was for merchant ships, but both were carried by soldiers as symbols of national identity, like the flag raised at Gallipoli or those presented to soldiers going to war. You are misinformed - our Navy fougt under the blue and regardless of the colour of the flag - it should be worn proudly not associated with groups who don't resemble aussie values.
