Hailing from northern and southern suburbs, readers reported car accidents, garden destruction and near-misses with deer at night, with many saying the problem had become worse in recent months.

"They are out of control in Figtree," Vanessa Rasmussen said on Facebook.

"If you drive at night up around Bellevue Road or Jacaranda [Road] they are all over the road and so dangerous!"

Further north, Adam Goss said he hit a deer at Helensburgh two weeks ago.

"The front of my car suggests the culling isn't working. Not a pleasant experience for me, nor the dead doe."

John McNeice said the deer were "all over the place at the minute" behind the Buddhist temple at Berkeley.

The comments flooded in after the Mercury reported that the Illawarra's feral deer population was spiralling out of control, after a lively Wollongong council debate revealed that 1400 had been shot through a council-funded program since 2011.

Greens councillor George Takacs told the council that more than 100 deer had been spotted traversing Gwynneville's Robsons Road early one morning, and he said it appeared the ruminant population was continuing to rise.

With funding for the culling program due to cease next June, Mr Takacs said he planned to raise a notice of motion to address the "underrated issue" and would be calling for more support from state and federal governments.

Keira MP Ryan Park has also joined the cause, writing to NSW Environment Minister Mark Speakman last week to request state funding. The Labor MP said he was regularly contacted by fed-up residents from Figtree, Mount Keira, Keiraville and Mount Pleasant.

Mr Park noted Wollongong council had made "efforts to carry out significant deer culls", but said residents wanted more to be done given the extensive damage to private and public land.

Melbourne-based hunting group, the Australian Deer Association (ADA) also believes a wider, more strategic approach is needed to get the deer under control.

ADA executive officer Barry Howlett said his association should be "part of the conversation" in addressing Wollongong's feral deer problem, as he said it was already running a successful hunting program on the outskirts of Melbourne.

"This has been an ongoing issue for years," he said.

"It needs to be a strategic effort, as councils just don't have the funds and expertise to deal with this stuff."
