As has been mentioned engine choice and the cars produced here where not determined by anyone here.
The ford territory/falcon should have had the 2.7tdv6 in 2004-5 the same year the ford owned LR introduced it with Peugeot. Instead it took almost 8 years to get into the territory.

We used to build the corolla and pulsar here. My sisters corolla, last of the oz built ones, is a 1.8 and has done 400,000 km. The pulsar production in Australia was having fewer faults than the parents Japanese line.
Both shut and moved .
The other biggest issue is export. Ford never tried or allowed oz built to export, and it's territory looks just like the next gen disco. It would have sold well in uk/eu/usa with a tdv6 and turbo petrol from 2005. Both the falcon and commodore would have sold in china but not allowed. And ford could have replaced it's crown Victoria(35 year old design with rwd solid axle low power v8, mainly sold to police) in the us anytime over the last decade with a much higher performance falcon turbo 6 or v8 but chose not to.
The difference between us and UK is the uk Govt sat down with the manufacturing sector and said how can we help you build and export more. So are now on the path to building more cars than ever,1972 was their peak, with half being exports.
