In the last few years, the issue of mobilisation for war has, in Australia at any rate, shifted from the arcane to the highly pertinent. Concerns publicly manifested in the government’s 2020 Defence Strategic Update, which asserted that the long-held notion of up to 10 years’ warning for a possible conventional attack on Australia had – as 10-year rules tend to eventually do – evaporated. Moreover, it alluded to what was thought to be a remote, but nevertheless alarming, possibility of a ‘high-intensity conflict’ in Australia’s region. Suddenly, generating combat power, perhaps more than what was readily to hand, has taken on some urgency.
