Song by Rolf Harris (I don't know if this was the original, though).

(Spoken) There's an old stockman, lying, dying. He props himself up on one elbow, turns to his mates, who are gathered round, and says:

Watch me wallaby's feed, mate
Watch me wallaby's feed.
They're a dangerous breed, mate,
So watch me wallaby's feed.

Tie me kangaroo down, sport,
Tie me kangaroo down.
Tie me kangaroo down, sport,
Tie me kangaroo down.

Keep me cockatoo cool, Curl,
Keep me cockatoo cool.
Don't go acting the fool, Curl,
Just keep me cockatoo cool.

(refrain)

Take me koala back, Jack,
Take me koala back.
He lives somewhere out on the track, Mac,
so take me koals back

(refrain)

Mind me platypus duck, Bill,
Mind me platypus duck.
Don't let him go running amuck, Bill,
Mind me platypus duck.

(refrain)

Play your didgeridoo, Blue,
Play you didgeridoo.
Keep playing 'til I shoot through, Blue,
Play your didgeridoo.

(refrain)

Tan me hide when I'm dead, Fred.
Tan me hide when I'm dead.
So we tanned his hide when he died, Clyde
And that's it hanging in the shed!

(refrain)
