*The Wilderness Society defines 'deforestation' as:
Loss of natural forest as a result of:
i) conversion to a non-forest land use;
ii) conversion to a plantation forest; or
iii) human activity that reduces forest species composition, structure or function so that it is significantly ecologically and structurally different from the primary forest of the site.
Includes conversion for agriculture, resources and mining, infrastructure, urban development and thinning of forests for non-forest uses.
- Calculations are based on 746,677 hectares of deforestation and land clearing in 2018-19 across Australia, 2,045 hectares per day, 85 hectares per hour, 1.42 hectares per minute. 1.42 hectares/60 seconds x 86 seconds = 2.03 hectares = close to the 2.02 hectare area of the MCG.

Proceedings of the National Academy of Sciences, 112(5): 4531-4540. Additionally, as at 4/9/20, the IUCN Red List database contained 84 extinct mammals across the world. Of these, 25 were from Australia plus another 3 were from Christmas Island. This is the highest number of extinct mammals recorded in any country globally.

- According to the Queensland Government's own Species Technical Committee Report into the impact of land clearing on threatened species, “Habitat loss is the most serious threat to koalas in Queensland and New South Wales (Martin and Handasyde 1999).” The report states that clearing leads to many direct deaths whilst also exposing koalas to additional threatening processes through habitat fragmentation.
