Personally, I don't like it and I can just see Uber using it as an excuse to (eventually) pay less to drivers in Australia.
I don't see it as a plan to reduce wages. However, it gives corporate the ability to improve driver satisfaction at no cost to themselves, and also indicate they support their "driver partners" so gives them a positive story to sell.
Of course, if it becomes accepted practice, drivers will rate lower if not tipped as they do in the US.
