$2.50 is the going rate for Qld honey buyers, unless you supply in an IBC Tank.
I would love $15-20 a kg, but obtaining certification to sell organic is; not worth the hassle or money.
My local Farmers Market got raided a few weeks back, (which I think was great) as there are many people there selling honey, competition is fine I have no problem with that, But I have the problem with all beekeepers who put Organic Honey on all their labels, and sell all their honey at a premium price without the supporting documentation. I looked in to obtaining Organic certification & it would be over $30k initially to obtain certification & over $7k per year to keep it current in Qld. (That being said, they nailed anyone who had an Organic sign up, without a current certificate of Organic Compliance displayed)
Unless you are in virgin land 10km's away from the nearest anything is you honey truly Organic & free of any pesticide residues? I am all for true organic, and because on your 30 acres you don't use chemicals at all, what is to say your neighbor is not selective spraying, this won't affect your bees, but it will leave a residue in your honey or nectar.
