I don't think they dropped any really. The government also didn't implement a lot of the reforms and revisions it said it would (or was recommended to) for imported cars (like large scale dealership or company imported) which would have put decent amount of competition in and given Australia access to some really interesting cars, although parts of that were as a result of "industry consultation" under the guise of consumer protection which just means the government is putting car companies (won't say manufacturers for this one) first. I think with the influx of Chinese cars it would make sense to traditional manufacturers to lower their prices here, particularly for commercial vehcles and utes, I think they know this too but it hasn't happened. If it is greed then all it would take is one manufacturer to cut their prices slightly to gain an upper hand for a time and the rest to follow provided all the manufacturers aren't coluding or whatever, but nobody has. I'd be fairly confident that they're well aware they can only rely on the cheap reputation of Chinese cars for a few years which is coming to an end soon, especially when it comes to fleet which will probably pick up for Chinese utes soon. I think there's a decent amount of other contributing reasons as to why there hasn't been a reduction.
