are there any friuts native to australia or the south pacific region that are suitable for making wine/brandy?

I'm not planning in making any wine or brandy, but I'm writing a story that needs a suitable native alchohal, not one made from imported friuts.

no

Ohelo berries from Hawaii.

Steve Irwin! Just kidding! :)

My aunt makes a really delicious wine from peaches.

do you have dandelions over there? Not much better than dandelion wine. How bout apples=brandy

There's kava, which some Aborigines use to produce an alternative to alcohol.
