Readiness and combat sustainment are crucial in war as @RobertClark87 points out. The ADF, like the UK Armed Forces, can 'fight tonight' but Australia must develop the means to stay in a high intensity major power protracted war that lasts months or even years. I suspect at the moment, we'd run out of critical munitions within weeks at best, and our vital fuel supplies are largely undefended. A good start would be to expand and accelerate GWEO, beyond GMLRS assembly and PrSM to other munitions, and start investing heavily into mass manufacture of low-cost armed drones, and also invest in sustainable logistics, and resilient and defended infrastructure. C2 must be also defended from both kinetic attack and cyber / counterspace threats. And we need to spend much more on EW and electromagnetic warfare capabilities. And its not just about military readiness, resilience and sustainability - its about building national readiness and resilience too. Not just in anticipation of natural disasters such as bushfires and floods - but in anticipation of protracted high intensity major power war happening in the Indo-Pacific region that would see Australia a combatant alongside our allies and partners. This has to be a whole of nation effort. And we need to do this fast - not in a decade's time - but to be ready for a real threat of such a war emerging within this decade.
