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.
Australia's shock is an import and use shock. The Australian electrical-machinery import total was 32,236,249.17. That figure is thousands of U.S. dollars. WITS prints China at 15,779,700.50 in the same units. China's calculated share of Australian electrical-machinery imports is 48.95 percent. There is no Australian leading-edge wafer line in the sources used here.
Lanes that keep shipping finished electrical goods are the United States, Vietnam, Malaysia, Germany, Korea, Thailand, and Japan. The calculated United States share of Australian electrical-machinery imports is 11.86 percent. Other Asia, nes on this chapter is 866,831.82 thousand dollars, a small direct line beside China, and it carries the code-490 caveat.
Bare chips are a thin bill next to finished goods. WITS prints Australian integrated-circuit imports at 539,259.35 thousand dollars. Calculated from that total and the electrical-machinery total, bare chips are 1.67 percent of the electrical-machinery bill. The calculated Other Asia, nes share of Australian integrated-circuit imports is 19.95 percent. The Taiwan hit is the silicon inside everyone else's boxes, plus that residual, not a domestic foundry.
The retailer cash figure is a user of electronics, not a fab. Group sales were 10,554.8 million dollars. Inventories were 1,298.5 million dollars. The retailer operated 348 stores. Inventory turnover printed at 6.71 times. The presentation labels the group sales total in Australian dollars.
Local import prices were still falling in the last observed quarter. Telecommunications equipment import prices fell 5.5 percent. The import price index fell 1.9 percent through the year. The war analog for memory is global, not that quarterly decline. Memory contract prices rose over 20 percent in a month.
Taiwan exposure is still four different global numbers, because the chips are made elsewhere. TrendForce prints TSMC at 67 percent foundry share. TSMC's Foundry 2.0 share is 34 percent. Advanced wafer revenue was 69 percent. HPC was 51 percent of net revenue. Equipment trade is a separate customs line. None of these is an Australian content census.
The 0–3 month operational analog is the same global lead time Australian buyers would face. The May print was 18 weeks. That is not the full-year memory sales peak.
Wave 1 for Australia is ports, air freight's gateways, customs systems, and data centres and network operators. Wave 2 is importers, distributors, contract assemblers, and the finance that rides on cargo. Wave 3 is installers, repair benches, and niche design firms. ACSC is a co-author of the CISA alert used as the threat baseline.
China trade stops the largest finished-goods origin. China's calculated share of Australian electrical-machinery imports is 48.95 percent. The printed China line is 15,779,700.50 thousand dollars against a world total of 32,236,249.17.
What keeps shipping is not a domestic fab. The United States is 3,823,654.86 thousand dollars, Vietnam 2,684,244.23, Malaysia 907,628.57, Germany 900,918.83, Korea 612,825.44, Thailand 522,115.62, and Japan 424,933.93. The calculated United States share of Australian electrical-machinery imports is 11.86 percent.
Taiwan exports slow on a small direct chip bill and on the chips inside third-country goods. Other Asia, nes is 107,592.22 thousand dollars of integrated circuits, the largest chip partner. The calculated Other Asia, nes share of Australian integrated-circuit imports is 19.95 percent. UN Comtrade says Taiwan, Province of China is code 490, Other Asia, not elsewhere specified, and that other unspecified Asian territories can also fall in that code.
China is also a large direct chip partner, at 96,473.31 thousand dollars, and Malaysia is 82,526.50. Malaysia keeps shipping. China does not. Direct chip dollars remain small beside the 32,236,249.17 thousand dollar electrical-machinery bill.
The wafer those imports depend on is concentrated even though Australia does not buy it as a wafer. TSMC was 67 percent of foundry market share in the TrendForce quarter. Advanced technologies were 69 percent of TSMC wafer revenue. Taiwan capacity in the SEMI reprint is 5.8 million wafers per month. Those are global manufacturing facts, not Australian factory output.
Retail stock is the buffer that is actually printed. Inventories were 1,298.5 million dollars. The slide text says inventory was 1.30 billion dollars, up 18.7 percent or 204.8 million dollars. Inventory turnover printed at 6.71 times, down 27 basis points. A days-of-supply conversion is not printed, and this report does not invent one.
Cyber risk reaches Australian critical infrastructure through the same advisory. ACSC is listed as a co-author. The alert says actors are pre-positioning for disruptive or destructive activity against critical infrastructure in a major crisis or conflict with the United States. Australia is aligned in this scenario, so ports and network operators are treated as Wave 1.
Short-horizon price analog, global contract and not Australian CPI: DDR4 contract prices rose over 20 percent in a month. The local baseline in the same window is the opposite direction. Telecommunications equipment import prices fell 5.5 percent.
Short-horizon time analog: chip lead times increased by seven days to 18 weeks in May. The May print was 18 weeks. Power-management lead times hit 25.6 weeks. The full-year memory sales peak is not this band.
Half-year materials analog faced by devices Australia imports: China's primary low-purity gallium price rose 17 percent, from 325 dollars per kilogram in January to 380 in June. By October the price was 420 dollars per kilogram.
The Australian full-year price baseline is a decline. The import price index fell 1.9 percent through the year. The global full-year product analog is separate. Memory product sales rose 79.3 percent. Global sales reached 791.7 billion dollars, up 25.6 percent. Those global figures are not Australian import-price index points.
Wave 1 is critical infrastructure and the border: container ports, the gateways air freight depends on, customs systems, and data centres and network operators. ACSC co-authored the CISA alert on PRC pre-positioning against critical infrastructure in a crisis or conflict.
Wave 2 is the enterprise import chain: finished-goods importers, component distributors, contract assemblers, the national retailer, industrial users indirectly, and trade finance indirectly.
Wave 3 is smaller firms: field installers, warranty benches, and niche device designers.

Decision-changing limits. Australia's electronics exposure is the import bill and the retailer stock. Bare chips are 1.67 percent of the electrical-machinery bill, calculated from the two WITS world totals. Other Asia, nes is code 490 and is not pure Taiwan. The 67 percent, 34 percent, 69 percent, over 60 percent, and more than 90 percent figures are different Taiwan statistics. The 100 percent gallium reliance and the December 2024 ban are U.S. facts. Australian gallium reliance, contract-manufacturer headcount, distributor days of inventory, port TEU, data-centre capex, and cargo-premium rates are unpublished here. JB Hi-Fi New Zealand sales are shown in New Zealand dollars and are not added to the Australian column. Days of cover are not derived from the 6.71 times turnover.

Calculated shares, rounded to two decimal places, are 48.95, 11.86, 19.95, 17.89, 15.30, 1.67, and 18.77 percent. Each uses a pair printed on the cited pages. The 18.77 percent is Taiwan equipment imports from the United States divided by Taiwan equipment imports, and it is not an Australian share.
Cyber tags are a planning model. Ports and data centres are Wave 1 direct. Air freight and customs holds are Wave 1 indirect. Importers, distributors, contract manufacturers, and the national retailer are Wave 2 direct. Industrial users and trade finance are Wave 2 indirect. Installers, repair benches, and niche designers are Wave 3 direct.
The SIA sentence on the second product category says memory increased by 34.8 percent in 2024 to 223.1 billion dollars, inside a 2025 release. That year clause is not used. The factbook's 79.3 percent memory increase is the full-year product analog that is used, and it is not an Australian price index. The 20 percent DDR4 figure is a floor because the page says over 20 percent.
