Frozen/pre-packaged veggies and Quarantine

Hey folks, just a quick question for all you seasoned travellers out there ;)

After a few trips across the centre and around the top it's become a bit of a pain for us not having fresh veggies/salad for meals (we camp self contained at night). Does anyone know what the quarantine regs across the various states are for pre-packaged frozen veggies? I've looked at the "topics" and even tried searching through the various government web sites but can't find an answer.

Do they still count as "fresh" and have to be disposed of, or can we use these to at least feel like we're eating healthy food?

And yes it does occur to me that I should have asked for myself last time I went through ;)

Cheers,

Chris
