Wonder why a new imported car is far more expensive in Australia than most other countries?
Because, I'm told, the Australian authorities again crash test examples, despite being crash tested and approved/certified in their country of manufacture. And the Australian authorities purportedly test to the same international safety standards.
Bit like the horrific expense around the old DCA "First of Type" aircraft certification of years gone by. It was a junket of incredible proportions, first class air travel, weeks overseas at the aircraft factory, lavish wining and dining, all to reach a similar Australian certification conclusion (plus a few expensive modifications required to justify the junket) as the original aircraft manufacturer and the regulator in the country of manufacture.
Australian Governments repetitiously continues to reinvented the wheel.
