@MLClark feijoa sounds like a MΔori word, too
I looked up, and it's apparently named after a Portuguese botanist, J. da Silva FeijΓ³, from 1760-1824. That explains why it's most commonly called "guayabo del Brasil"! Thanks for the excuse to go deep-diving into etymology!

Yesss! Apparently Colombia and New Zealand are the world's major producers. :) Makes sense Australia would have access too!
