Several rescues from bushland around the Hunter region recently have prompted a warning for bushwalkers and park users to be better prepared as temperatures drop.
Yesterday, a man was brought safely out of the Watagans National Park at Cooranbong after spending up to four nights lost in freezing conditions.
Last month, a woman was rescued after going missing in the Yengo National Park while on a bike ride.
Rescue helicopter crewman Glen Ramplin said the man rescued yesterday was suffering from serious hypothermia.
"So, I guess in the cooler months the snakes aren't out and about in the bush, so it's probably a good time to go bushwalking," he said.
"It's not so hot but, then again, it does get cold so people have to pack for the environment they are going in."
