I don't think there's any benifit of donig this at all! Especially if you live in Australia! The other side of the world!
Why not just buy off a well established Dam seed bank? I completely understand if you wanna do a taste test and then get seeds, but most of the best can easily be bought online or in a headshop..
Dampkring - Kiwiseeds - Cannabis, Marijuana seeds, Amsterdam Seedbank, Buy online - Dampkring coffee shops use these I reccomend Maco or Tasman haze, both absolutely amazing, or ocean's 12.
Untitled Document - These are sold by the coffeeshop brand Greenhouse and have to say they are V. V. good! All colour coded now too, so however many you get, you can always tell them apart even in the one box.
Piwiseeds | Top quality weed marijuana hemp cannabis seeds from Piwiseeds.com - They sold these in Katsu coffeeshop, they have the best bud in the Dam there, but I don't recognise anything they specialised in.. Shame!
Nirvana Seeds Shop Marijuana Seeds Cannabis Seeds Free and Cheap Cannabis Seeds - Another very popular brand, not too many coffeeshops actually sold the bud from these seeds, but some did, and a few Growshops too.
Cannabis & Marihuana - Last but not least, Sensi! The original..
I'm sure you have prolly heard of them all before, but having been to the Dam a total of 4 weeks, doing nothing but smoking, I can tell you you're safe with any of them, with no need to go to the Dam to deliver them to your house personally. And most seed companies are well stealth!
Good luck in your quest!
