TL;DR: Can I bring dried chillies to Australia?
Dried chillies/capsicum are not permitted and will be destroyed, unless they meet the exclusions listed on the Department of Agriculture, Fisheries and Forestry's urgent actions to protect against khapra beetle webpage.
The Department of Agriculture page above (under "Spices") is seemingly unambiguous, but clicking on that webpage to find out what exactly "meets the exclusions" leads to a maze of twisty regulations, all alike. Chillies from khapra beetle target risk countries are clearly completely banned, but can I bring them in for personal use from other countries not on the list, like Malaysia or Mexico?
