A 2027 U.S.–China conflict with Australia aligned to the U.S. China trade stops immediately, Taiwan exports are slowed/limited, and China launches large‑scale cyber disruption in waves. Planning scenario, not a forecast. No end date is set.

What happens

Australia is structurally import-dependent for vehicles. FCAI-reported 2025 sales totalled 1,209,808 units, and China supplied about 18 percent of that series. CarExpert's 2025 origin count, on a 1,241,037-unit market, puts Japan at 28.9 percent (358,981), China at 20.4 percent (252,928), Thailand at 20.1 percent (249,958), and Korea at 12.1 percent (149,966). Japan, Thailand, and Korea keep shipping when China stops. The two China shares use different denominators and are not averaged. Some brands do not report sales to VFACTS.
fcai.com.au carexpert.com.au
China is the second‑largest country of origin for new vehicles and accounts for 77.5% of BEV sales YTD 2025, so the EV supply chain is especially exposed.
goauto.com.au
Australia’s vehicle parc is large and ageing: 22.3M registered motor vehicles and average age ~11.54 years in 2025, increasing dependence on parts and repair when new supply tightens.
bitre.gov.au
Downstream impact is broad: dealer networks (3,700+ dealerships), aftermarket repair, fleets, and used‑vehicle markets absorb supply shocks quickly.
aada.asn.au aaaa.com.au
Port Kembla handles 100 percent of New South Wales motor vehicle imports. Those vehicles leave the port on a site NSW Ports serves with 3.5 kilometres of road and 29 kilometres of rail, on high-productivity vehicle routes. Port of Melbourne handled 386,402 new motor vehicles in FY2024-25. A truck-versus-rail split for the vehicles themselves is not published.
nswports.com.au nswports.com.au portofmelbourne.com
Repairs stop when parts stop, not only when finished vehicles stop. AAAA-commissioned research put automotive parts imports at $4.05 billion in 2023-24, with China the largest source at $915 million. UN Comtrade via World Bank WITS puts 2024 HS 8708 parts imports at $3,125.7 million, of which China was $678.7 million, the United States $752.7 million, Thailand $284.2 million, and Japan $261.6 million. The two parts series cover different years and scopes.

Financing and insurance are meaningful shock channels: ABS shows $4.9B in new loan commitments for road vehicles in Sep Qtr 2025; average comprehensive motor premium reached $1,052 in 2024 with average claim size $5,202 (up 42.2% since 2019).

Why Australian Automotive Gets Hit in a War

A China trade stop removes finished vehicles sourced from China, about 18 percent of FCAI-reported 2025 sales (1,209,808 units) and 20.4 percent (252,928 units) of CarExpert's 1,241,037-unit origin count. It does not remove Japan at 28.9 percent (358,981), Thailand at 20.1 percent (249,958), or Korea at 12.1 percent (149,966). Australia has no mass-market plant to fall back on.
fcai.com.au carexpert.com.au toyota.com.au
The repair channel fails on parts, not only on missing new cars. Parts imports were $4.05 billion in 2023-24, and China was the largest source at $915 million. In the 2024 HS 8708 series China was $678.7 million of $3,125.7 million, behind the United States at $752.7 million, with Thailand at $284.2 million and Japan at $261.6 million still shipping.
paintandpanel.com.au wits.worldbank.org
China and Taiwan disruptions hit battery-electric supply hardest. China supplied 77.5 percent of BEV sales year to date in 2025. The Taiwan piece is indirect: chips arrive inside the imported vehicle. TSMC's 2024 net revenue was 5 percent automotive by platform. Dealer waits of 3 to 12 months in 2022 are the observed propagation, not a foundry-revenue share.
goauto.com.au investor.tsmc.com abc.net.au
Port Kembla handles 100 percent of New South Wales motor vehicle imports. Vehicles leave that site on 3.5 kilometres of road and 29 kilometres of rail that NSW Ports manages. Port of Melbourne handled 386,402 new motor vehicles in FY2024-25. A truck-versus-rail split for the vehicles is not published.

How hard, how soon

0–3 months

Short-horizon analog: dealers were already quoting waits of 3 months in 2022, the front of a reported 3-to-12-month range. Biosecurity holds at the vehicle port run on a weeks scale. The accumulated new-car rise of about 25 percent and the used-car rise of about 50 percent are not this 90-day band.
abc.net.au abc.net.au
Same-month price print: dealer used car prices declined by a further 0.6 percent in November 2024, and market days' supply moved to 62 days, under the 70-day benchmark. That monthly move is the current 0–3 month price analog. The accumulated price rises are not this band.
coxautoinc.com.au

1–6 months

Accumulated shortage analog, not a 90-day print: new vehicles rose about 25 percent and used vehicles about 50 percent while waits ran from 3 to 12 months. The Cox used-price index was still 134 in May 2024, about 34 percent above December 2019.
abc.net.au coxautoinc.com.au

12+ months

Long-tail analog: Insurance Council data show new vehicle prices in some segments up to 39 percent and used vehicles around 32 percent from 2019 to 2024. Average claim size reached $5,202, up 42.2 percent since 2019. Keys-to-keys repair time reached 61.25 days in 2024, from 38.57 days in 2019. The paper also states an increase of 58.06 percent. Those day counts are used as printed. The 58.06 percent is the paper's stated increase and is not treated as the result of subtracting the two day counts. Passenger-car rental prices were 69.81 percent higher in 2024 than in 2019, and rental cars are about 5 percent of insurers' claims costs.

What to watch

China-sourced new-vehicle deliveries, year over year. Act when China-sourced deliveries fall more than 30 percent year over year. China was about 18 percent of FCAI-reported 2025 sales (1,209,808 units) and 20.4 percent (252,928 units) of the 1,241,037-unit origin count. Thirty percent is a planning tripwire against that baseline, not an FCAI rule.
fcai.com.au carexpert.com.au
Used-vehicle days' supply. Act when used days' supply prints below 50. Cox reported 64 days in May 2024 and 62 days in November 2024, both under a 70-day benchmark. Fifty days is a planning tripwire below those prints, not a Cox rule.
coxautoinc.com.au coxautoinc.com.au
Port Kembla vehicle throughput or biosecurity hold. Act when Port Kembla vehicle throughput falls more than 25 percent for two consecutive weeks, or when a biosecurity hold runs longer than 14 days. Port Kembla handles 100 percent of New South Wales motor vehicle imports. The agriculture department requires a full external and internal inspection of used vehicles on arrival unless a recognised offshore treatment provider has processed them, and that page does not state a standard number of days. The 14-day line is a planning tripwire. The retained ABC quarantine page did not yield a measured hold length.
nswports.com.au portauthoritynsw.com.au portofmelbourne.com abc.net.au agriculture.gov.au
Average comprehensive claim size, year over year. Act when average claim size rises more than 10 percent year over year, or when keys-to-keys repair time prints above 61.25 days. The observed average claim size was $5,202 in 2024, up 42.2 percent since 2019, and the observed repair time was 61.25 days in 2024 against 38.57 days in 2019. Ten percent is a planning tripwire against the claim-size path, not an Insurance Council rule. The 61.25-day line is the latest printed average.

What is not known

Cyber wave order is a planning model. It is not a count of attacks on each auto sub-industry. Ports are Wave 1 direct. Inland car-carrier road and rail is Wave 1 indirect, because the week-1 failure is the port. Parts importers are Wave 2 direct. Dealer rooftops and collision workshops are Wave 3 direct. Dealer management systems are Wave 2 direct. Those are different nodes.
cyber.gov.au cyber.gov.au
Decision-changing limits. The FCAI series (about 18 percent of 1,209,808 sales) and CarExpert's origin count (a 1,241,037-unit market; China 20.4 percent and 252,928 units; Japan 28.9 percent; Thailand 20.1 percent; Korea 12.1 percent) use different denominators and are not averaged. CarExpert notes that some brands do not report sales to VFACTS. Parts imports of $4.05 billion in 2023-24, with China at $915 million, are not the same series as 2024 HS 8708 imports of $3,125.7 million, with China at $678.7 million, the United States at $752.7 million, Thailand at $284.2 million, and Japan at $261.6 million. The 3.5 kilometres of road and 29 kilometres of rail are the on-port network NSW Ports describes for agriculture, construction, and mining. A truck-versus-rail split for the vehicles is not published. TSMC automotive revenue at 5 percent of 2024 net revenue is not the chip content of an imported vehicle. The 69 percent advanced-node share and the 68.8 percent foundry-revenue share are not that content either. Waits of 3 months are the front of a 3-to-12-month COVID range. The 25 percent and 50 percent price rises are the accumulated shortage, not a 90-day print. The 39 percent and 32 percent figures run from 2019 to 2024. Tripwires at a 30 percent drop in China-sourced deliveries, used days' supply below 50, a 25 percent Port Kembla drop, a biosecurity hold longer than 14 days, and a 10 percent rise in claim size are planning lines set against those baselines.

The Ukraine wiring-harness stoppages of 2022 show that one component can halt a line. They are the wrong geography for a China stop. Australian harness supply is not claimed to be Chinese on the basis of that incident. https://www.prismark.com/what-s-new does not publish a printed-circuit-board production share, so no China PCB share is stated. https://www.abc.net.au/news/2023-08-29/port-kembla-vehicle-ship-quarantine/102784988 is retained and is not used as a measured day count.

COVID and insurance-cost analogs are severity baselines. A war-driven China trade stop, plus a Taiwan export restriction and a cyber campaign, can diverge from that path in timing and in which substitutes exist.
abc.net.au insurancecouncil.com.au
Later primaries and their limits. The 2019 freight report says 98 percent of vehicles arrive on roll-on/roll-off ships and that the vast majority of the inland task moves by road. It does not publish a truck-versus-rail percentage. The per-car costs of about AUD 240 and about AUD 540 are marked circa. Keys-to-keys days are used as printed, 61.25 in 2024 and 38.57 in 2019. The paper's stated increase of 58.06 percent is not treated as the result of subtracting those day counts. The panelbeater count is 11,400 on an ANZSCO profile the page says will not be updated again. Cox's November 2024 print is a further decline of 0.6 percent in dealer used prices and a move to 62 days of supply. The May 2021 MIC comment is a contract-manufacturing share for microcontrollers, not the chip content of an imported vehicle. The agriculture department page requires a full external and internal inspection of used vehicles unless a recognised offshore treatment provider has processed them, and it states no standard number of days. Ten percent of the $5,202 average claim is $520.20, calculated here. The Insurance Council does not publish that increment.
