I had to go back into my notes to check but here in New Zealand, I was taught the Whitaker model (Monera, Protista, Fungi, Plantae, Animalia). I've literally never heard of archae-/eubacteria in my life haha. That said my lecturer was basically like "taxonomists are always fighting over everything so don't worry about it too much." I do remember them talking about domains more than kingdoms though.

The definition they gave for protista was unicellular and colonial eukaryotes, giving protozoans and fungi as examples
