To, "Drop A Bear"? I wouldn't know how
So, someone, please do tell me now
Don't think it'd me my of tea, cup
'Cause first I'd have to pick one up!

excerpt from Australian government travel advice for overseas visitors, which may be helpful.
To the tune of My old man's a dustman.
 
 
If you come down under,
and go into the bush.
Stay out in the open,
avoid the parts thats lush
 
 
And always wear a big hat,
it keeps you out of sight
and if its very windy
be sure it fits on tight
 
But, if you hear a rustle,
from high up in a tree
it means that there's a drop bear
about to pounce on thee.
