Just thought that i would let all Taswegian Thermie Lovers know that i have just recently come across a fantastic farm selling meat direct to the public - Conmurra Farm (
https://www.facebook.com/#!/Conmurra.Farm) conmurrafarm@bigpond.com. Although not exactly a co-op, I thought locals may be interested. The farm is on the East Tamar, and they deliver statewide (free for orders over $60). Their prices are very good, and the meat we have tried so far is superb, eg sides of lamb $75 or on special we purchased at $65 for the side, $8.50kg for skinless chicken breasts, around $9kg for premium mince. I love buying local, and cutting out all of the expensive "middle men"! They currently only have a facebook site (above) and the e-mail and phone (03 63 301 695) but are currently building a website.
By the way, I have no affiliation with the farm/business, just a very happy customer spreading the word!
