Maps of Australian temperature variables are available at the Bureau of Meteorology – Maps and gridded spatial data.
Site-specific measurements or model outputs
Data on Australian climate variables from 1889 to the present in point and grid form are available at Long Paddock – SILO (Scientific Information for Land Owners)
Notes
The relevant target and time period for high/low temperature stress will depend on the production system, target productivity level and climate, e.g. sheep production is particularly vulnerable to cold stress at lambing and immediately after shearing, and heat stress at joining and during pregnancy. Furthermore, heat and cold stress can be affected by numerous variables in addition to air temperature, therefore a heat or cold stress index may be more appropriate than a simple temperature threshold.

Maps of Australian bushfire activity showing area burnt this year, last year and two years ago are available at MyFireWatch.
Maps of northern Australian fire histories since the year 2000 are available at North Australia & Rangelands Fire Information (NAFI) Maps showing historical burnt areas across Australia from the early 1900s through to 2023 are available at the Digital Atlas of Australia – Historical Bushfire Boundaries.
Site-specific measurements or model outputs
Data on northern Australian fire history since the year 2000 are available at North Australia & Rangelands Fire Information (NAFI) Data on Victorian fire history are available at DataVic – Fire History showing the number of times areas have been burnt, based on mapped fire history (scars).
Data on global monthly burnt areas are available at the Land Processes Distributed Active Archive Center (LP DAAC) – MODIS/Terra+Aqua Burned Area Monthly L3 Global 500m SIN Grid V061.
Notes
As bushfire events are likely to be relatively infrequent, it may be appropriate to express this metric as the rolling average for a representative period, e.g. the last 30 years. Note that this measure is not simply the inverse of the related impact metric, as the impact metric may include areas burned outside the relevant ecosystem area, whereas the dependency metric only includes areas burned within the relevant ecosystem area.
