You have to declare food which means you go through the Red channel.officer usually asks what we have-"packaged curry paste".is that all."yes".Ok off you go.
With a tribe of sweet-tooths - we run out of space to write down all the different foods/items that we want to declare. The worst (in last 5 years) was around 24 to 25 kg of chocolate/jelly sweets/Xmas Puddings/Xmas cakes/biscuits/Schnaps etc.
No matter how much we warn the scanner people; "That bag is VERY heavy" -they look at our daughters and shrug right before they dislocate their shoulder or near enough.
Declare everything, and if you arrive at the same time as flights originating in Asia - they wave you straight through in Sydney.
I did get stopped years ago with the 4.5kg Toblerone though. The custom's lady was contemplating having to open it to ensure no drugs were hidden inside. She had lots of volunteer customs officers willing to help in the process.
