I'm a little suspicious of this claim. Oh, sure, it makes sense that an Aussie figured out a new way to drink Foster's, but if he were really an Australian his name would be Robbo.
Australians don't drink Foster's. Seriously...NOBODY. We send it overseas because it tastes like crap.The generic lagers of choice for Australians are XXXX (literally Four Ex), Toohey's New and VB (short for Victoria Bitter).
