Another well-known antipodean (probably only well-known in New Zealand actually) contribution that has to be mentioned is "Fast Pair of Skis" by Harold Gretton:

I like to go tramping around Dawson Falls
The climate's superb and the scenery enthralls
There's pungas and fushias and mamaku trees
It's a swell place to go with a fast pair of skis.

When it's cold, and you freeze,
You can always keep warm with a fast pair of skis

King David lay dying and couldn't get warm
So they brought a fair virgin to take him by storm
Said David, To hell with prescriptions like these
Tell the eunuchs to bring me a fast pair of skis

etc. etc. (circa 1940s - I remember my parents still singing this in the 70s)
