Would anyone have any information re these three RAAF personnel buried in Gilgil CWGC Cemetery

Three RAAF Sergeants date of death 23 April 1942 - an assumption would be a 'crew', but I have no further info, just noticed their names whilst checking out other info re Gilgil GWGC, they are the only Australians buried there
