Global Events Driving the Cost Rise
🦠
COVID-19 Global PandemicMar 2020
Construction sites shut across Australia. Import supply chains disrupted. Cost pressures initially muted — then exploded as demand rebounded.
Cost impact: +0.4% in 2020, followed by +18% over 2021
🏠
HomeBuilder Scheme LaunchedJun 2020
Government stimulus offering $25,000 grants for new homes. Created an immediate demand surge — builders booked out 12–18 months. Trades prices rose sharply as capacity was overwhelmed.
Cost impact: Added estimated $15,000–$25,000 to average build cost due to trades premium
🪵
Global Timber CrisisJan 2021
Framing lumber prices rose 130% globally in 12 months. North American sawmill shutdowns during COVID combined with surging US housing demand created a worldwide shortage.
Cost impact: Framing and structural timber: +40–60% vs 2019
🚢
Suez Canal BlockageMar 2021
Ever Given grounded for 6 days — halted $9.6B/day in global trade. Compounded an already strained shipping container shortage.
Cost impact: Imported materials: +15–25% freight premiums through to mid-2022
⚔️
Russia Invades UkraineFeb 2022
Russia and Ukraine supply ~30% of global steel and significant shares of nickel, aluminium, and neon gas. Energy prices spiked and fed through to Australian LNG prices.
Cost impact: Structural steel: +22–30%. Reinforcing bar: +35%. Energy-intensive materials: +15–20%
📈
RBA Begins Rate HikesMay 2022
Cash rate rose from 0.1% to 4.35% in 13 months. Builder financing costs rose sharply. Fixed-price contracts signed in 2021 became loss-making.
Cost impact: Financing costs: +200–300bps. Triggered wave of builder insolvencies.
👷
Labour Shortage Crisis2022–2023
Closure of international borders during COVID eliminated 45,000 working holiday visa workers from the construction labour pool. Trades were booked 12–18 months in advance.
Cost impact: Labour cost per dwelling: up 20–30% vs 2019 baseline
📊
Elevated Plateau2023–2025
Cost growth has slowed but costs remain 55–60% above 2019. The structural factors (labour shortages, tight trades capacity, elevated materials) have not unwound.
Cost impact: Current build cost: $3,800–$5,500/m² for social housing — vs $2,200–$3,100/m² in 2019

NEW BUILD COST RISE SINCE 2019
New home builds are now $250,000–$280,000 more expensive than 2019. With 13 RBA rate hikes, mortgage serviceability dropped sharply — more buyers pushed into rentals.
Public Sector Capacity
−44%
HOMES PER $1B VS 2019
