23% — the median of 6 frontier models, resolving by 2029-10-17.

Answer

Gemini (Google): 27% — Sustained high immigration and bulk commodity exports typically buffer aggregate GDP even during severe per-capita downturns. Australia has recorded only two technical recessions since 1991, yielding an annual baseline probability below 15%. Net overseas migration adds roughly 1.5% to top-line output annually, requiring a severe domestic demand collapse to turn GDP negative. A sharper-than-expected slump in Chinese steel production cratering iron ore export values would most quickly push this into reality.

Answer

Claude (Anthropic): 17% — Hinges on whether a China/commodity demand shock or household debt stress triggers two straight negative GDP quarters by end-2027. Australia hasn't had a technical recession since 1991 (excluding brief COVID dip), showing strong structural resilience via immigration-driven population growth and… High household debt and reliance on China commodity demand are genuine vulnerabilities, but current trajectory shows moderating inflation, rate cuts, and stable labor… A sharp China slowdown or global recession spillover combined with a housing-debt shock would be the key trigger that could flip this probability materially higher.

Answer

GPT (OpenAI): 24% — It turns chiefly on whether a China/commodity shock or domestic debt squeeze overcomes Australia’s policy buffers. ABS needs to publish adjacent quarterly contractions by Q4 2027; the RBA, Treasury and fiscal policy can respond before that. Australia has avoided technical recessions for long stretches, with 2020 the recent exception, so a two-quarter fall in 14 months is below base rate. A sharp Chinese demand collapse, sustained unemployment rise, or housing-credit stress would materially raise the odds.

Answer

Grok (xAI): 28% — Whether RBA policy or China demand delivers two successive negative ABS GDP prints by Q4 2027. Only five remaining quarters (Q4 2026–Q4 2027) can produce a consecutive pair, last chance Q3–Q4 2027. Post-1991 Australia recorded just one technical recession (COVID); a 15-month window therefore carries a ~12–18 % base rate, lifted here by record household debt. A sharp China commodity slump or RBA overtightening would raise the odds most; otherwise growth stays positive if modest.

Answer

DeepSeek (DeepSeek): 22% — Australia needs a genuine demand shock, not just weak per-capita growth, to print two negative quarters by end-2027. RBA cash rate near 3.5% and a still-tight labour market mean the trigger must come from offshore: a China property slump or US tariff shock hitting iron ore and coal. ABS quarterly GDP has fallen only four times since 1991; the last technical recession was 2020's COVID quarter, so the base rate for any two-quarter run in a three-year… This case sits slightly above base rate because household debt near 190% of income makes consumption fragile, but immigration-driven population growth keeps aggregate…

Answer

Qwen (Alibaba): 14% — Population growth and RBA rate cuts provide a floor; a China-driven commodity shock is the most plausible trigger. Australia has had only two recessions in 35 years; headline GDP is further cushioned by ~2% annual population growth, making consecutive negative quarters rare. The RBA retains room to cut the cash rate from current levels if growth falters, and fiscal policy has historically been deployed quickly to avoid technical recessions. A sharp fall in iron ore or LNG prices driven by a deeper Chinese downturn is the single scenario that would most move this probability upward.
