Can anyone tell me if you have to declare two boxes of cigarettes when entering Australia ?

One person can only bring one bag. If you bring more, you need to declare and pay taxes, and the tax amount is not small.

Now you can only bring one box. If you don't declare it and get caught, the fine is very severe.

Go through the self-service immigration channel. No one checks, but they do check if you go through the declaration channel. No one twenty sticks
