Sending seeds internationally can get complicated. You might be better off trying locally on Ebay, or looking up local garden clubs/associations.

Not selling these seeds. Hoping someone can use them. I would appreciate refund for postage.

It'll still be the same thing, difficulty sending them internationally. You might find the Post Office will refuse to accept them, or the quarantine authorities at the other end might seize and destroy them. But there could be people in the local gardening clubs who might like to try them. I remember years ago the Sydney Botanical Gardens had quite a few of them, they looked quite good.

That is very generous. Wish I had someplace to put a palm like that. Are the seeds edible? If so, have you tried them?

Edible? Never entered my mind. The possums do not eat them (eat everything else). Someone might know but I am not game enough to try.
