The thing with customs is to be honest. If you have food with you of any kind just check food. I had chocolate, biscuits and some rolls with me on the trip over here from Norway. I marked food and the inspector asked me about what kind of food and I told him, he just said okey have a nice day and pointed me to the exit. In Australia everything is xrayed anyway so you have to decleare it otherwise you will get a 220 AUD fine even if the food you bring is allowed.
