That says a lot. How do they define the term "traditional" I wonder? Do they restrict it to Australian Traditional?
If they'll allow "Anon" as traditional -- you've got more scope. (I wouldn't but I wouldn't be running anything under those rules).
I'd say -- act innocent. Sing anything that's not actually written by anyone still alive and smile a lot.
And --- yes -- I'm on a roll here -- if it has to be Australian --sing anything you like from anywhere and say it was collected here. It probably was anyway. Keep singing, Kathryn -- all the songs you love anywhere you can get away with it.
