Yep, that first letter (way back when I asked) they sent was misleading. I didn't get the impression that treatment was necessary at all. But that's an example of how our quarantine system works. It doesn't. It's Russian roulette for seeds. Depending who you ask you'll get different answers and they will apply the supposed rules differently. They don't check all mail coming in so what's the point of their rules anyway? I think 'they' (holders of the collective official environmental management memories) are still sore over bringing the cane toad in and everything since then is just a performance to try and make themselves (and us) feel like they're fixing their mistakes and being vigilant.
