In October 2026 a report card produced by the National Vertebrate Pest Coordinators found every state and territory failing or floundering in its efforts to control feral deer, with one notable exception. South Australia, which launched an ambitious statewide eradication plan in 2022, received a green in all four categories assessed. According to the report, the state had decreased the abundance, distribution and environmental and agricultural impacts of deer (The Guardian, 30 October 2026).
SA is the benchmark
South Australia’s results are impressive. Its decisive, statewide programs show how to deliver large-scale, rapid outcomes. We are keen to see how other states learn from SA’s leadership and its proactive approach to acting quickly on feral deer and pigs.
What we are seeing in Queensland and NSW
Deer numbers are increasing across the eastern states, and populations are expanding quickly throughout NSW and Queensland.
We usually find deer with our thermal drones, but not always. In February 2026, driving into town near Goondiwindi at about 7:45 pm, we passed a pair standing by the road, and they were still there an hour later on the way back out. Feral deer are increasing in numbers across Queensland.
Act before it’s a pig-sized problem
Feral pigs show what happens when populations are left to build. With deer, there is still time to act, but the window is closing. Thermal drone surveys can show where deer are and how many, and aerial programs can then deliver results at landscape scale.
Have you seen deer on your property? Let us know.
