Native wildlife are facing even more danger on Macarthur's busy roads as ongoing drought conditions continue to worsen.
The drought, among other reasons, has led to an increase in the number of wildlife being killed on the region's roads recently.
Wollondilly Councils sustainability projects officer Damion Stirling said roadkill rates had steadily increased over the past two to three years.
But he said dry, hot conditions weren't the only reason more animals were dying on local roads.
"I think it is a combination of drought, limited food resources and the increasing levels of greenfields development removing the grassland habitats where many native animals graze," Mr Stirling said.
"Native animals are venturing into more urbanised areas due to lack of food availability. We are definitely seeing a decrease in water availability from the drought however evidence is also coming to light that mining within water catchment areas is also diminishing water resources."
Mr Stirling said the animals most in danger of being hit by a car in Macarthur were wombats, kangaroos and wallabies.
Transport for NSW has also received reports of increased numbers of wildlife taking to the roads in search of food and water.
Acting director for operations Jonathon Crocke said feeding areas created from road surface water runoff were drawing kangaroos and wallabies in particular to the roadside.
"The large number of fires throughout the north of NSW has also had a significant impact on the increased movement of wildlife," he said.
"Animals can be highly unpredictable, so drivers need to take care."
Mr Stirling urged motorists to report any roadkill or injured animal sightings.
"Check if the animal is alive and if it has any pouch young if the animal is alive contact Wollondilly WIRES, Sydney Wildlife or Wildlife Rescue South Coast," he said.
"If the animal is dead move the carcass to the side of road if it is safe to do so."
