Pommies (singular = Pommie) comes from Pom or Pome which stands for prisoner of mother england, which is a strange one, considering Pommies are what Australians call Englanders, but Australians were the ones who were prisoners of england (way back when Australia was a penal colony).nother etymology suggests it is short for pompous [citation needed], a quality often attributed by Australians to the British.[citation needed] The use of the word 'Pom' is contentious. Many British people living in Australasia find the term offensive and demeaning.
