Having taken his proposal for International Australia Day to the United Nations and Donald Trump in New York, reviewed Curtis Stone’s G’day USA menu in LA and encouraged the entire world to become more like Australia, Sam is back in town for his highly anticipated local rant.

In an attempt to remind fellow Australians to throw a lamb chop on the barbie and celebrate International Australia Day on January 26, Sam has named and shamed those guilty of gross acts of local unAustralianism over the last year:

"My fellow Australians, as Lambassador of our great nation, I’ve been urging the rest of the world to follow our example and eat lamb on International Australia Day," Kekovich said.

"But that doesn’t mean us Aussies should rest on our laurels.

"UnAustralian behaviour was still a very real problem in Australia over the last year."

As examples he cited the following:

• "Vegemite, a national icon, was smeared with the name iSnack2.0. iSack would have been more appropriate – the whole marketing department, for starters. (Or maybe iRack, for a bit more of a lamb flavour.)

• "What about shock jock Kyle Sandilands? If he put a lamb cutlet in his mouth now and then, instead of his foot, he might not have been punted so often.

• "Speaking of the Punter, what was Ricky Ponting doing popping Swisse vitamin pills during the Ashes, instead of a few nutritious, juicy Aussie lamb chops? He was doing ads for them as well. No wonder the Poms got the better of us.

• "And while I’m on the Poms, what about Prince William coming over for a visit, but not hanging around for Australia Day? Thank goodness he attended a lamb barbie while he was here, or he shouldn’t have bothered coming at all."

Kekovich says "unAustralianism remains a threat to our way of life".

"Which is why on International Australia Day, every Aussie needs to join the rest of the planet, in throwing lots of nice juicy lamb chops on the barbie," he said.
