Cheer up and take heart in the fact that even in these tough times of austerity they did at least commit to buying 58 more Joint Strike Fighters for $12.4 billion. Cut down on sicence and buy more flying lemons, at least they have a sound strategy.
That $12.4 billion buys them the continued good will of the world's strongest military power. It's not really about the Australian air force, it's simply cheap insurance.
My country does the same but only half heartedly tries to claim it's all about strengthening the air force. Hell, if we're really lucky there might actually be some decent jet fighters in it for us in the end. That's not the main point though.
