Im from Australia and here is the version i know:

Aunty Mary had a canary
she also had a duck
she took them behind the drawers
and taught them how to
fry eggs for breakfast
fry egg for tea
the more you eat
the more you drink
the more you want to
Peter had a boat
the boat began to rock
up jumped jaws and bit him on the
cocktails ginger ale
40 cents a glass
if you dont like it
you can shove it up your
ask no questions
tell no lies
i saw a chinaman
doing up his
flys are bad
mosquitos are worse
that is the end
to my dirty little verse.

Enjoy.
