OK so did he not know who his father was or that his father had a foreign nationality ???

I thought the father was going to be from a third world country like Obama’s was...well New Zealand is like an extreme foreign country to the Aussies ...the jealousy, etc

There’s been a long time feud between Aussies and New Zealanders...

The latter.

Barnaby Joyce's father, James Joyce, migrated to Australia from New Zealand in 1947. The concept of New Zealand citizenship did not exist until 1949 - at the time of his migration to Australia, James Joyce was simply a British subject, not a New Zealand citizen.
