The decision follows a three-day trial on farming properties in South Australia that used thermal-assisted aerial control of fallow and red deer in the Limestone Coast region.
For decades, aerial culling has been used on a variety of species including wild pigs.
Now the thermal technology can be used by marksmen culling deer from the air.
The bulk of feral deer can be found in NSW and Victoria, while populations are also growing in South Australia, Queensland, Tasmania and the ACT.
The animal is known to cause damage to agriculture and the environment.
With estimates the feral population could be as high as as two million deer, Australia last year appointed its first National Deer Management co-ordinator, Annelise Wiebkin, to tackle deer numbers.
Dr Wiebkin said the number and spread of deer was growing in parts of Australia, and the use of thermal cameras would help turn that around.
"We can expect to see deer increasing in new areas every year," she said.
"This trial has shown that it can work at pulling out more deer from dense vegetation than we've been able to before.
"It is an additional tool in the tool kit ... hopefully more people will trial it in new areas on different species of deer.’’
There are six species of feral deer in Australia, with the animal introduced into the country by European settlers in the 19th century.
A 2019 survey undertaken by the Australian Bureau of Agricultural and Resource Economics and Sciences found land managers spent an average of $2627 a year per property on feral deer control activities, up from $2218 in 2016.
