Tom Derrick is another Australianwho could have been awarded two.
James Cowey is worth looking up, not a VC recipient but he fought as an enlisted man at both gallipoli and kokoda.
for the non australians out there, gollipoli and kokoda and THE two battles most tied up in the mythology of australians at war, for my generation someone having served at either equals instant respect. having fought at both is just mind boggling.
