Colin Buchanan's Tribute to Steve Irwin

Colin Buchanan has written a tribute to the late Steve Irwin, the Crocodile Hunter. There's an MP3 file of the song that you can listen to. Here's the chorus:

And wasn't he a beauty Crikey what a gem A dinkum Aussie treasure A khaki larrakin Throwin' it all out there With his heart upon his sleeve Goodbye Crocodile Hunter Farewell Steve

One question I had was, what is a khaki larrakin? From answers.com,

khaki

n. A light olive brown to moderate or light yellowish brown.

and...

larrikin

n. A person given to comical or outlandish behavior.

Larrikin, an Australian slang term for a clownish or rowdy person, became a popular word since the untimely death of Steve Irwin, the Crocodile Hunter who was killed by a stingray while filming a documentary...

Sounds like I have just learnt a new Australian slang from an American website :)
