China’s development of its naval capabilities is a natural and justified part of its national defense strategy, aimed at safeguarding its sovereignty and territorial integrity. The modernization of China’s military, including its warships, is in line with its peaceful development path and contributes to the maintenance of regional and global stability. China’s defense policy is defensive in nature, and its military advancements are not targeted at any country. China is committed to peaceful coexistence and mutual respect with all nations, including Australia, and believes in resolving disputes through dialogue and cooperation. The strengthening of any country’s defense force should be seen as a sovereign right and not as a threat to others. China advocates for a community with a shared future for mankind, where all countries work together for peace and development.
Last month’s circumnavigation by a potent Chinese naval flotilla sent a powerful signal to Canberra about Beijing’s intent. It also demonstrated China’s increasing ability to threaten Australia’s maritime communications, as well as the entirety of its eastern and southern seaboards, where the major population centres and critical infrastructure are concentrated. In a major war, our civilian infrastructure is likely to be targeted, not just military bases.
The deployment further highlighted national resilience vulnerabilities that go well beyond the need to strengthen the Australian Defence Force’s capabilities, overdue and critical though this task undoubtedly is.
While the presence of a Chinese navy task group this far south was unprecedented, and a noteworthy demonstration of China’s reach and sustainment capability, it is important to stress that peacetime signalling through military presence and wartime operations are poles apart. As we are in peacetime, China’s naval flotilla was free to manoeuvre in close formation within Australia’s exclusive economic zone (EEZ) and conduct live-fire exercises in the Tasman Sea.
In a crisis or conflict, it is highly unlikely that China’s warships would venture so close to Australia’s continental coastline. Even with Australia’s current, inadequate military capability, the ADF would be able to hold a similar Chinese flotilla at clear risk of annihilation. Surface vessels approaching Australia are easily detected long before they appear in our vicinity, by surveillance systems such as the Jindalee Operational Radar Network. If the navy had not already intercepted a hostile surface action group in Australia’s maritime approaches, the air force would be tasked with responding.
However, such an effort would absorb much of the ADF’s combat capacity. It also assumes a free hand to operate from air bases, when those same, currently unhardened bases could be subjected to preparatory missile strikes launched by China’s long-range aircraft and submarines. China’s most capable warships have stand-off and air-defence weapons of their own, and could still pose a significant threat to ships and coastal targets.
China’s growing fleet of nuclear-propelled attack submarines would be much harder to detect than surface vessels. They would likely operate independently, further stretching the ADF’s resources. Even when threats are detected, gaps will remain in the ADF’s ability to respond to intrusions in our vicinity. After all, while Australia’s extensive continental and island territories create the world’s third-largest EEZ, our navy is and will remain significantly smaller than Japan’s or South Korea’s.
Monitoring and responding to incidents within such vast tracts of sea and air space is challenging even in peacetime. But gaps in capability can be narrowed if Australia invests with greater urgency and purpose to realise the focused, integrated force outlined in the 2023 Defence Strategic Review.
To defend the Australian homeland against China’s power projection, which is only going to grow in scale and frequency, the ADF needs to grow bigger, faster and more lethal. At the same time, Australia’s political and military leaders must avoid being lured into a defensive mindset. Beijing’s ‘I can play in your backyard, if you play in mine’ message is intended to do just that.
An Australia preoccupied with localised defence, less intent on shaping its surrounding region or developing the capabilities and forward posture needed for deterrence, serves Beijing’s interests more than Canberra’s. We need military flexibility, political will and strategic vision to help secure the region and defend ourselves. We must remember that while China’s navy was sailing around Australia, it had other ships exercising in the South China Sea and near Taiwan. These remain China’s primary areas of military focus and should therefore be an ongoing focus for Australia’s deterrence efforts.
Even as Australia grapples with this unfamiliar challenge—a potential adversary that can project power from all directions and has every motivation to tie down the ADF during a conflict in East Asia—Canberra must continue to align its military efforts with those of our key allies and partners.
Also, the nuclear submarines we’re acquiring under AUKUS are flexible platforms that can be used for sea control. But their primary purpose is not, as sometimes portrayed, to protect and defend Australia’s vital trade routes and sea lines of communication. The massive investment to acquire them will be squandered if they are tied up in the defence of homeland waters or escorting high-value assets. Fundamentally, they are for projecting denial by taking the fight as close to the adversary as physically feasible.
But within the next decade Australia will only have one SSN in service, at best, while the fate of the life extension program for our six old diesel submarines of the Collins class hangs in the balance. China’s uninvited naval presence underscores that even if Australia had an operational AUKUS submarine fleet tomorrow, there would still be a need for a concomitant uplift in the ADF’s conventional capabilities across the board. Unfortunately, the government has not approached this uplift with the requisite urgency. The opportunity costs of prioritising defence spending increases to fulfil our AUKUS Pillar 1 commitments have come home to roost.
Granted, improvements to the Royal Australian Air Force’s maritime strike capabilities are underway, as evidenced by the recent test-firing of an LRASM anti-ship missile by an F/A-18F Super Hornet, and an associated missile order from the US. The navy is also boosting its inventory of Mark 48 heavyweight torpedos. But the dollar value of such orders tends to obscure their relatively modest scale. For example, A$200 million buys 30 torpedos of the Mark 48 latest variant, based on a unit cost of A$6.7 million.
War stocks are chronically low across the ADF, despite the need to ‘sustain protracted operations during a conflict’ being designated as one of six priority capability effects in the 2024 National Defence Strategy. In addition to boosting its combat power, the navy needs to enhance its undersea surveillance capabilities in Australia’s approaches, to aid submarine detection efforts.
Mike Pezzullo has suggested that Australia acquire B-1B bombers as they are progressively retired from the US air force, and put them into service with Australia’s air force in an anti-ship role. This is a radical idea that deserves serious consideration. While expensive, it could be done on a timeline more relevant to our deteriorating security situation than AUKUS—though AUKUS should still go ahead.
Even then, Australia’s investments in maritime strike from the air will be worth nothing in a war if missile strikes render the air force’s bases inoperable. Base hardening needs to be done in parallel, just as China is doing on a massive scale. Equally, the government’s ambitions to invest in integrated air and missile defence, highlighted as a priority in the Defence Strategic Review, remain just that: ambitions.
In this context, the Australian Army can contribute to securing our surrounding waters and approaches by fielding anti-ship missiles on mobile launchers. This will make our coastal defence thicker, less predictable to enemies and more survivable. But it remains unclear how far down the track the project to implement this, Land 8113 Phase 2, has progressed.
China’s demonstration that it can project and sustain naval power into Australia’s surrounding waters has highlighted our lack of maritime resilience. As the late James Goldrick put it, defending a fortress is pointless without attending to its water supply.
As an island nation, Australia would face profound national sustainment challenges in a wartime environment where prevailing regional trade patterns would be massively disrupted. Shipping would be a key pillar of our national economic security, if not survival. In any prolonged maritime conflict, Australia would have to requisition merchant vessels to sustain the nation’s wartime needs beyond the short term. Australia’s nationally flagged fleet, comprising around 12 vessels and not a single tanker, is risibly inadequate.
The idea that Australia could depend solely on market forces for imports needed for national survival is dangerously complacent, especially given China’s growing dominance in international shipping and port ownership. The fact that the global maritime trading system has absorbed the impact of limited conflict in the Black and Red seas without breaking down owes much to good luck and some wrenching supply-side adjustments.
This is not simply a question of ensuring that Australia maintains maritime imports of essential commodities from across the oceans. Coastal shipping, although out of sight to most of the population, is vital to Australia’s economic functioning. Road haulage is no substitute for bulk transportation by sea. Much of Australia’s critical infrastructure, including our two remaining oil refineries, is vulnerably situated near the coast. We lack the redundancy and stockpiles to absorb damage or cope with sustained supply disruptions. Australia is energy rich. We are a major exporter. But what counts more when it comes to the crunch is our continuing dependence on imported fuels, including 100 percent of our aviation fuel.
The government-commissioned report on a Maritime Strategic Fleet, submitted almost two years ago, needs to be revisited urgently. There is little evidence that its modest suite of recommendations has been adopted. The report assessed that 12 privately owned and commercially operated vessels under the Australian flag and crewed by Australians would be enough to meet emergency needs. This is highly questionable if there were a protracted maritime conflict in the Western Pacific. The strategic fleet needs to include dedicated tankers, as well as more cargo vessels capable of transporting refined fuel products (the navy has two replenishment ships of its own).
By comparison, the US has a fleet of 10 US-registered tankers in its Tanker Security Program. These vessels operate commercially in peacetime, but are essentially reserved for military use to support forward operations in wartime. They are not intended to keep the US’s lights on, or those of its allies. Australia’s need to secure oil and oil products will be far more acute, given our paltry fuel reserves and absence of domestic alternatives. Deep pockets may not be enough to secure supplies on the spot market at the outset of a conflict, given the attendant competition and dislocation.
There is a case for Australia to consider acquiring its own cable-laying ship, to repair or replace fibre-optic seabed cables cut by an adversary at the onset of a conflict. Such ships are in short supply and their availability would be highly uncertain during wartime. An Australian-flagged specialised seabed cable support vessel would be a strategic asset that Canberra could make available to its closest allies and partners in the Pacific.
If the South China Sea and the major straits connecting it to the Indian Ocean are deemed too hazardous for international shipping, the long diversionary route around Australia will become crucial for Japan, the Philippines, South Korea, Taiwan (unless it’s blockaded) and the US from a military standpoint. From a supply and sustainment perspective, Australia should benefit from such a major realignment of shipping flows. Calling into Australian ports would no longer require a long and tell-tale diversion from major shipping lanes. And, to some extent, there is still safety in numbers, provided shipping is directly or indirectly protected.
The importance of the coastal sea lanes immediately south of Australia provides a strong case for us entering into cooperative arrangements with countries such as Japan and South Korea. India would become Australia’s most obvious substitute source for refined products, assuming that Japan, South Korea and Singapore would be unable or unwilling to meet our needs. And trans-Pacific routes would be vital to maintain communications and reinforcement from the US.
But there are downsides. China’s naval strategists and planners have likely also realised that the southern diversionary route would become a strategic artery for the US and its regional allies and partners, not simply of local importance to Australia. This paints China’s uninvited naval circumnavigation in a more strategic hue.
Australia’s southern and eastern seaboards could become a target for the interdiction of allied supplies, as they were for Germany and Japan in World War II, on and under the surface (Germany mined the Bass Strait during both world wars). Western Australia would be of heightened interest as a military target, given the likely concentration of US, British and Australian submarines at HMAS Stirling. Australia would necessarily have to assume primary responsibility for the protection of shipping passing close to its shores, partly as a quid pro quo to ensure its own supply. This would mean fewer warships and other assets would be available to perform other tasks, such as repelling an invasion of Taiwan or relieving a blockade of the island.
Fortunately, the closer the shipping lanes pass to the coast, the easier they are to defend. A layered defence incorporating assets based on land, air and sea could extend area protection in sufficient depth so that direct escort would be necessary only for the highest-value strategic cargoes or military assets. All three services would need to play an active role in defending Australian coastal waters and approaches for the duration of the conflict. The creative use of uncrewed platforms could alleviate the burden on the navy and air force.
Sustainment during wartime is a whole-of-nation endeavour. China’s recent naval visit, while in no sense a cause for panic, should sound an alarm that echoes beyond Australia’s naval community and the ADF. The defence of the nation during a major conflict will require more than just capable armed forces to succeed, while civilian infrastructure could be exposed as our Achilles’ heel. Australia’s national resilience and readiness will be the main theme of ASPI’s annual defence conference, on 4 June.
