S.1Abstract
Australia enters 2027 as a high-income, highly urbanised country that is also a large net energy exporter, an arid-continent water system and one of the most fire-exposed populations in the world. Its resident population reached 27.92 million at 31 March 2026, growing 1.4% in a year, about three quarters of it through net overseas migration1. Emissions excluding land use were 591.5 Mt CO₂e in 2024, against 605.2 Mt in 20198. The legislated targets are 43% below 2005 by 2030 and net zero by 2050, and a 2035 target of 62 to 70% below 2005 was set in September 2025181920. Wind and solar supplied 33% of electricity in 2025, and fossil fuels still supplied 61%16. Australia exports more energy than twice what it uses, yet the baseline holds no bound figure for liquid-fuel stock depth11. Agriculture, forestry and fishing used about 68% of the water consumed in 2023–245. The 2019–20 Black Summer fires burnt about 24 million hectares, killed 33 people directly and were linked to an estimated 417 smoke-related deaths2223. This Baseline Edition fixes the reference state for Australia’s water, energy, food, health and biodiversity systems from sources that could be read at evidence close. Where a national dataset could not be read, it shows as a designed empty state that names the source and the blocker. The edition ranks nothing and decides nothing.
S.2Key messages
Six readings that frame the Australia baseline, and the eight questions this edition answers, each with its status and source.
591.5 Mt CO₂e excluding land use in 2024. The position against 2005 is not bound.8
Where do emissions stand?Reported
43% below 2005 by 2030, a 2035 range of 62 to 70%, and net zero by 2050.181920
What are the targets?Reported
Wind and solar 33%, fossil fuels 61% and coal 43% in 2025.16
How is electricity supplied?Reported
17,223 GL consumed in 2023–24, about 68% by agriculture, forestry and fishing.5
How much water is used, and by whom?Reported
About 24 million hectares burnt, 33 direct deaths and an estimated 417 smoke-related deaths.2223
How severe was the last national fire season?Reported
27.92 million, up 1.4% in a year; life expectancy 81.1 and 85.1 years.13
How is the population changing?Reported
Insured and uninsured loss series are not bound in this edition.36
Who carries disaster losses?Not bound
Fire, smoke, heat and grid stress coinciding in the populated south-east. SCN-AUS-FIR-01
What will Q1 2027 test first?Expert input
S.3Headline finding
ReportedEQL 4NRF-COUNTRY-AUS-2026-BASELINE-CLI-005
The 2019–20 Black Summer fires burnt about 24 million hectares, killed 33 people directly and destroyed more than 3,000 buildings; smoke was linked to an estimated 417 further deaths.
| Item | Bar, scaled to the largest value | Value |
|---|---|---|
| Direct deaths | 33 | |
| Smoke-related deaths (estimate) | 417 |
Sources: Royal Commission22; Medical Journal of Australia study23.
The fires harmed people far from the fire front. Smoke reached the large coastal cities, so the exposed population was far larger than the burnt area suggests. Fire is therefore a health, water-quality and service-continuity question as well as a land question2223.
S.4At a glance
S.5What each steward reads in it
GCRI · KEY T
Technical Truth
The evidence supports a coupled reading of Australian risk: fire, heat and dry years act on water, energy and health together.
GRF · KEY M
Public Meaning
For most people risk arrives as a smoke day, a heat warning or a water restriction.
GRA · KEY F
Capital Meaning
Readiness implications only. Insured and uninsured loss series are not bound, and climate-related financial disclosure standards now apply to large entities.
NEXUS
Synthesis
Australia publishes strong statistics on population and water and a clear legal frame for emissions.
S.6What this edition is, and is not
What this edition is
A baseline: the state of Australia’s water, energy, food, health and biodiversity systems in 2026, the dependencies that connect them, the risks that travel through them and the capabilities that hold them. It sets out the questions the operational series will answer.
What it is not
Not a national risk assessment, an official warning or a rating. It decides nothing about any institution or asset. Competent authorities keep every mandate they hold, and national ownership of the series is unaffected.
What comes next
Q1 2027 opens the operational series with a sealed Foundry evidence cut. Each later edition reports what changed against this baseline, new observations, source revisions, method changes, scenario updates and corrections.
Notes
Numbers are the edition’s reference numbers, so a note reads the same in every chapter. The full list, with every source and its licence, is in Annex C. Annex C, references
