lol, now I doubt you were even in Australia at all. Or you are simply and blatantly lying.
First of all, you claim only the Cabin body was manufactured by Chinese, this is NOT TRUE.
In fact, according to both the Sydney Morning Herald and Manufacturer weekly, only the Driver and Guard Cabin of the train are build and assembled by the Australian in Cardiff Workshop.

Quoting Sydney Morning Herald
The electric fit out and the interior fit-out were the responsibility of Chinese contractor. The Downer and Hitachi only responsible for implementing and design the software and the construction of driver and guard cabin.
Another point is that Sydney Train transport the first two train set back to China for refit due to the first two test train does not have any safety feature and air conditioning suggested that the interior of the train was worked in China instead of Australian, and to a point where refitting them in Cardiff plant would cost more than sending it back to China can be seen as a major fault how these Chinese train was.
Quote Daily telegraph
The Train, being delayed for average 4 months which required the Cardiff plant to fix many of the mistake Chinese contractor made during the fabrication of the train as quote by the same SMH article
The Channel 10 News were supposed to high light how the train project delayed for 17 months and almost bankrupt the Australian Contractor Downer. You asked for proof the Aussie don't like the train when it rolled out, and proof that the train are poorly build, here another article by Daily Telegraph point out how wrong bolt supposed to be bolted to the seat find its way to waratah train.

So, are there enough "Proof" for you to see the Chinese made train were troubled? You can find A LOT More by googling waratah train.
So there, either you are an emu (Which dug your head in the sand) or you are simply lying, END-OF-STORY
Can you read English?
A liar would always call others lying

Construction and delivery)
The joint venture between Downer EDi Rail and Hitachi was established to design, manufacture and commission the trains.[1] The stainless steel bodies are partially constructed by Changchun Railway Vehicles in China before being shipped to Downer EDI’s Cardiff Locomotive Workshops facility for final assembly, testing and commissioning.[1] The manufacturing facility at Cardiff received an upgrade of over $20 million to cater for the needs of the project.[1] Other infrastructure works included the construction of a the Auburn Maintenance Centre and new substations at various locations around the network.[1
