Interesting observations Jack and Norm,
Self sufficiency? We gave that away a long time ago.
AVB, while I love the internal combustion engine, there is nothing necessarily non repairable about electric motors, nor circuit boards. I have been farting around with them and repairing electrical components for years. Does that mean I want to replace my mower/car/etc with an electric type? not particularly, but that is the way things are heading.
For example, there have been a few attempted start ups for Australian electric vehicles here, all of which have been squashed by the current government. 
And when push comes to shove, I actually think that is one area Australia could definately compete in and become 'self sufficient'. We won't though, because the powers that be will be too busy selling any advantage away for a few dollars more. See the natural gas debacle for an example, where it is cheaper for Australia to buy its own gas from Japan. 
Words fail me.
