Yeah, I don't disagree at all. Australia keeps running almost exclusively on trucking transportation. I didn't realise the lack of oil refining capacity... I can see how it would be an easy function to offshore, but it's obviously not very resilient.
As oil gets more expensive to extract (ie, drills have to go deeper, etc) and both shipping and trucking transportation gets more expensive as a result, Australia is definitely going to feel the pain of that lack of oil refining capabilities.
