If australian songs count here, I know another song. It's called "Botany Bay", one of the many ballads about the australian penal colony. YOu can find tune and text on this site: www.contemplator.com Go to "Songs of the sea". At the bottom of the site is "Other songs related to the sea and life on water". There are two different songs called "Botany Bay". Personally, I prefer the first. Oh, before I forget it: For the first version, there are two verses missing. Here they are:
It was on the 28th of may
From England we did steer
And everything being safe on board
We sail'd down the river clear
And every ship that we pass'd by
We heard the sailor's say:
"There goes a ship of clever hands
And they're boung for Botany Bay"

There is a girl in Manchester
A girl I know full well
And if I ever get my liberty
Along with her I'll dwell
Oh, then I mean to marry her
And no more go astray
I'll shun all evil company
Bid adieu to Botany Bay
