Concentrations at the same moment as the index above, for the pollutants both places report. Lower is better. The dark marks on the PM2.5 and PM10 rows show the WHO's 24-hour guidelines (15 and 45 µg/m³).
The past week
Which had cleaner air over the past 7 days?
Over the past 7 days, on modeled daily averages, Canberra averaged AQI 20 against 48, and it was the cleaner of the two on 7 of those days. A single reading can catch a city on a bad afternoon; the week says whether it was the weather or the place.

Deforestation · 2001–2025
Which has lost more forest, Brisbane or Canberra?
Canberra has lost more: about 1,290 ha of forest within 10 km of its center from 2001 to 2025, against 178 ha around Brisbane. 1,000 ha of that was cleared for good, for farms, mines or towns.
Measured within 10 km of each center, from the yearly satellite maps of forest loss: a wider circle than the one for tree cover, because forest is usually lost at a city's edges.
Worst year: 2007, with 33 ha lost.
Worst year: 2003, with 599 ha lost.

Trees
Which has more trees, Brisbane or Canberra?
Canberra has more tree cover: 42.2% of the land within 2 km of its center against 20.0% around Brisbane, or about 106,988 trees against 53,658.
The dark mark is each place's canopy target: 30% of the land, raised where air quality is poor.

Reading these numbers
How this comparison is made
Air quality index
The US EPA index, computed from current pollutant concentrations: ground stations where a place has them nearby, and the CAMS atmospheric model everywhere else. It moves hour to hour, so it is a snapshot rather than a verdict on either place. The guideline marks are from the WHO's 2021 air quality guidelines.
Trees and forest
Tree cover is the share of ground under canopy within 2 km of each center, read from Sentinel-2 satellite imagery at 10 m detail. It measures that circle, not the whole municipality, which is what makes the two comparable. Forest loss comes from the University of Maryland's Global Forest Change maps.
More on the method on the About Airleaf page.
Frequently asked
Brisbane vs Canberra: your questions answered
Is Canberra cleaner than Brisbane?
On air quality, yes, right now: Canberra reads AQI 8 against 11, a gap of 3 points on the US EPA index. This is a live reading rather than an annual average, so it can reverse within a day. Over the past 7 days, on modeled daily averages, Canberra averaged AQI 20 against 48, and it was the cleaner of the two on 7 of those days.
Is it safe to exercise outdoors in Brisbane and Canberra today?
The advice is the same for both today. Air quality is satisfactory for everyone. Brisbane reads AQI 11 and Canberra reads AQI 8.
Which has lost more forest, Brisbane or Canberra?
Canberra has lost more: about 1,290 ha of forest within 10 km of its center from 2001 to 2025, against 178 ha around Brisbane. 1,000 ha of that was cleared for good, for farms, mines or towns.
Which has more trees, Brisbane or Canberra?
Canberra has more tree cover: 42.2% of the land within 2 km of its center against 20.0% around Brisbane, or about 106,988 trees against 53,658. Both figures describe the same-sized circle of ground around each center, not the whole municipality.
How many more trees do Brisbane and Canberra need?
Brisbane needs about 26,829 more to reach its canopy target of 30%, and Canberra about 0 to reach 30%. The target starts at 30% of the land and rises where air quality is poor.
Are Brisbane and Canberra measured the same way?
The method is the same: the US EPA index for air, and Sentinel-2 satellite imagery at 10 m detail over an identical radius for trees. Both readings come from nearby ground stations. Nothing is adjusted for population, city limits or climate.
How often does the Brisbane vs Canberra comparison update?
The air readings refresh about once an hour, and each reading's local time is shown at the top of the page. Tree cover comes from the latest clear satellite image of each area (Sep 26, 2026 and Mar 14, 2026), and the forest figures are published yearly.
