Australia is famous for being strict on what you bring into the country. Early settlers once imported rabbits, which unsettled the local fauna and flora. Authorities are very wary of the risks of new products.
Obviously I want to bring some delicatessen to my hosts. So I have to inform what I can bring. It seems okay to import processed food as biscuits and chocolate. But I will make sure to declare it. I want to avoid fines and prosecution.
Luckily, Aussie government documents the do’s and don’ts of importing goods extensively. There is the Australian Quarantine and Inspection Service website, this brochure and also this smaller brochure which I found via the Australian Embassy in Brussels website. There is also a FAQ page.
