A report to the council indicated measures available were high-cost with low success rates, but mayor Reg Kidd said the bats had travelled to Orange prior to 2010 and every year since and had not necessarily roosted in the park, which does not have native trees.

"One of the colonies was on Dairy Creek Road where it goes off the Mitchell Highway and in Ploughmans Lane," he said.

Councillor Kevin Duffy said the council should be doing something, whether it be high-frequency noise or lights in the park "to see if it'll work".

"The bats in Ploughmans Lane were moved by cracking a stock whip and they moved somewhere else, I don't care where they go," he said.

"We're responsible for that park and the people of Orange are asking us to move them along - we could finish up simply where we start to lose the trees."

Councillor Tony Mileto asked whether signage could be added to the park during the months the bats roosted.

"Just a warning to keep an eye on the bats so they don't get surprised when they're sitting in a seat and a bat decides to [relieve itself] on it - it's not a pleasant experience," he said.

Community services director Scott Maunder said signs were possible.

Councillor Joanne McRae was wary about the cost of trialling measures and also supported signage, saying Tamworth Regional Council had gained funding from Local Government NSW for the project.

"In fact [there's] potential tourism impacts of people coming to look at them, rather than spending money to move them," she said.
