Down Under

Real or imagined, here are some comments I found on the web about the meaning of the song:

A Volkswagen Kombi is a minivan. It's fried-out because of the heat and it's probably overheating. Head full of Zombie refers to him being wasted on a head full of pot. The thunder I imagine is referring to the sound of the storms rolling over the hills, the smell of rain coming and the feeling you get before there's a big Aussie storm.

When he said "lying in a den in Bombay" He's referring to an opium den.

The 'men at work' are on their way to "Tanelorn" which is an annual Australian hippie music festival.

Vegimite is so Australian because it is made from vegetable and yeast residue from Australian Breweries, it tastes vile!

Chunder is also Australian slang, it means 'To vomit'

The Den in Bombay means they are in an Opium den, they have slack jaws because they are so high on opium, the man "trying to tempt him" was trying to sell him something crap and second rate, which he refused because he is Australian and "comes from the land of plenty" which has plenty of top notch stuff coming out of it.

And 'women glow' is also a funny euphemism for women sweating.
