Warning Time — 14 August 2026

Two stories dominated the week, and they point in opposite directions. Washington told us AUKUS is fine while sailing through the Taiwan Strait 56 per cent less often. Canberra told us AUKUS is "full steam ahead" while refusing to hold an inquiry into it. Meanwhile Indonesian warships drilled with the PLA Navy east of Taiwan, and our six Collins-class boats kept leaking. Pick your reassurance carefully.

The Big Movements

The Taiwan Strait transits collapsed 56 per cent. Nobody in Canberra mentioned it.

Breaking Defense reports US Navy Taiwan Strait transits have fallen 56 per cent under Trump 2.0. In the same week, the Pentagon's policy chief toured Asia praising AUKUS and warning "middle powers" to do more, US Marines certified their first Darwin-based SPMAGTF in fifteen years, and Trump told Albanese he'd consider a tariff reprieve.

Read those together. The rhetoric of commitment is intact. The routine, visible, physical act of contesting the water is down by more than half. Presence is the cheapest form of deterrence available to a superpower, and it's the one being quietly rationed. If the cheap thing is being cut, ask what happens to the expensive things.

Australia's response should not be another round of alliance reassurance-seeking. It should be capability we own. Every reassurance we accept in place of a hull, an interceptor or a missile line is a deferred payment on a debt that comes due in a crisis.

Six leaking submarines and another decade to go

19FortyFive has laid out the Collins-class problem plainly: leaks, overheating, excessive noise across all six boats, and they have to last another decade. That is Australia's entire submarine force. There is no reserve, no second fleet, no bridging option that exists today.

The AUKUS discourse this week was about politics, not steel. Peter Garrett publicly questioning whether AUKUS is a rip-off. Michael West reporting on the inquiry Canberra refused to hold. The Australian arguing that honesty from Canberra is the key to AUKUS's social licence. news.com.au flagging trouble. That last point is the serious one: a programme this long, this expensive and this politically exposed cannot survive on assertion alone.

Hold the inquiry. Not because AUKUS is wrong, but because a programme that runs to the 2050s needs bipartisan foundations that survive three or four changes of government. Refusing scrutiny doesn't protect the submarines. It hands the argument to the people who want them cancelled.

Indonesia drilled with the PLA Navy east of Taiwan

USNI News confirms Chinese and Indonesian warships exercised east of Taiwan. Taiwan has asked Jakarta why. It's a fair question, and one Canberra should be asking louder. Indonesia sits directly across every approach to Australia's north.

The same week, China's fourth Type 075 amphibious assault ship achieved combat qualification in the South China Sea, and ASPI warned that Russia's Pacific submarine fleet could tip the regional balance toward Beijing. The picture is not a single threat. It's a thickening of Chinese military options in exactly the waters our trade and our defence both depend on.

Indonesia is not lost, and treating it as lost would be the fastest way to lose it. But our northern diplomacy is under-resourced relative to its strategic weight. The Vietnam visit this week, three joint statements and a deepened Comprehensive Strategic Partnership, shows what serious Southeast Asian engagement looks like. Do that with Jakarta, at scale, now.

We're planning for the invasion. China would prefer a blockade.

ASPI's Strategist argues Australia is not ready for an economic blockade of Taiwan, and that our thinking remains fixed on kinetic invasion scenarios while Beijing's preferred instrument is maritime economic pressure. No shots fired, no clean casus belli, and our trade, LNG flows and resource exports disrupted anyway.

The supporting evidence arrived on schedule. Japan is struggling to secure rare earths for EVs and chip tools under Chinese pressure. Niche critical minerals are caught in a China supply squeeze. And Chinese EVs, led by BYD, are eating the Japanese automakers' Australian stronghold. Coercion doesn't need a war. It needs a chokepoint and a phone call.

The prescription is unglamorous: stockpiles, sovereign supply for the inputs that matter, and an economic-resilience plan that names the specific commodities and specific days of cover. Foreign Minister Wong's edict to universities to axe China research links is real decoupling in one narrow sector. Now apply the same seriousness to fuel, minerals and shipping.
