Someone suggested eucalyptus to give a beer an Australian flavor, but rightly pointed out that it probably would end in tears.
Well, how about a quandong beer? Quandong, also known as the native peach and bush plum, is an Australian native with a taste described variously as "tart apricot and peach" and "red wine". They are available dried and fresh.
A Google search will reveal more.
Because quandongs are quite tart, due to their high amount of vitamin C, I reckon they would be good to try it in a lager, perhaps to replace the raspberries or cherries in a fruit beer.
Has anyone ever tried this, or is anyone willing

Cheers,
Oliver
