From a reddit comment..

The guy seriously knows his Australian ecology.

I'll list out some of the amazing detail on flora and fauna he's put in there starting from the Allocasuarina littoralis tree the Black Cockatoos are sitting on. It's one of their favourite foods.

The frogs are probably Peron's tree frogs (Litoria peronii) based on the eyes and calls

Then the Angophora tree has the leaves in the right place

The spider orchid (Caladenia sp) in the grass

The waratah and sickle fern (maybe) in the possums hat

The old man banksia (Banksia serrata) as you stated

There's a lot more, but that's what stuck out to me. The guy's really done his homework while making that.

Some amazing details in this short vid.

Amazing detail. I don't know much about creating CG, but I can't imagine how tedious and time consuming it was to model and texture this, let alone animate it. By mostly one guy? wow

I know what you mean, the smooth flow and detailed movements in this era cartoon are amazingly detailed IMO.

Cartoons back then sure had a level of quality today's piles of animated trash can't even approach.
