Sunfish our car industry was killed of for one reason. The cost of labour when unskilled labour was between 70 to 90k a year. The unions priced them self out of work. Once ford pulled the pin the others had no option than to do the same. A couple of great Aussie invention was power steering a small company in Sydney held world wide patents when refuse ing to sell them to TRW they just brought the company and got the lot and the electric fan produced and in vented by Davis Craig now on every car in the world. How ever they never patented it sad it that is. We can produce anything and every thing we just need political will power to do it.
