I SELL plants and seeds online and I do send to west aus.
My seed is heirloom. I hAVe posted plants to WA without going through quarantine and there hasn't been a problem.
Gardeners are different. We been ignoring these restriction for eva. I live in Tassie nd the quarantine is the same, but I still get plants in the mail.
Haven't got caught yet. Can they catch you????????
