Given we've just celebrated Australia Day, it's worth noting that our national anthem works perfectly when sung to the tune of Gilligan's Island.
I remembered this as I was re-reading one of my favourite books - Confessions of a Thirteenth Man - by John Harms. A great read about a bloke who follows the 1998/99 Ashes tour around Australian in his 1982 Holden Camira (incredibly voted car of the year in 1982).
Go on, give it a go......
Australians all let us rejoice, for we are young and free
With golden soil and wealth for toil, our home is girt by sea
Our land abounds in nature's gifts of beauty rich and rare
In history's page let every stage advance Australia fair (Advance Australia fair)
