Finally, the Anzacs in the RAF carried a lot more than their weight. 35% of the Australians were killed, one of the highest rates of any nationality. Fighter Command's loss rate overall was 18% and the high Aussie losses are attributed to their frontline placements and extended tours.
"The Australian aces, Hughes, Millington, Mayers, Curchin, Cock and Hilary accounted for 60% of Australian claims and were characterised by their aggressive willingness to engage, marksmanship and a superior sense of their three-dimensional combat environment" (Adam Claasen in Dogfight:The Battle of Britain). Only Hughes and Hilary flew Spits, the others Hurricanes.
"Although Anzacs made up only approximTely 5% of Fighter Comman, they supplied nearly one-third of the top ten aces...between them, Hughes (Aust) and Carbury and Gray (NZ) took out 50 enemy machines in just 4 months."
