Brown Turkey is the only one standing our possible winter frost, down to -15 degrees Celsius, but I have some varieties that have a small root development, so they can be kept in a pot, and put in a frostfree place in winter: white ishia, everbearing, blanche d'argenteuil, petite negri and pingo de mel. They give me a crop each summer.
Fig trees can stan d frosts, but the very tiny fruit formed before the winter doesn't stand much frost, so this crop freezes mostly , but I get a late 'brown turkey' crop if the summer hasn't been to bad.
I don' know what part of Australia you are living in, if you live in the drier parts, drainage wouldn't be necessary, I think, but there are some wet parts , and combined with the sometimes heavy and red clay ground, I suspect the roots would rot away, as mine did,
