I'm noticing in the above video and also in two of the new MX's recently delivered in Perth with the tow package, that all have the one piece European tow hitch.
However, if you select the towing package, as I have done for our 100D, it currently says, "Compatible with hitch mount bike and ski carriers". To me this means it has the 2" square receiver which is common in Australia and accepts different tongues and more importantly, my bike carrier. This isn't what's supplied on the most recently delivered Australian 90D's I have seen or the 75D in the above tow test.
I'll be contacting my DS soon for clarification. Here's an article on Teslarati showing the 2" receiver

Anybody had theirs delivered in Australia with the 2" square receiver?
