A spate of dangerous interactions between tourists and feral horses in Kosciuszko National Park has prompted the NSW Government to consider closing a popular camping ground.

A National Parks and Wildlife Services risk assessment seen by the ABC shows in the lead-up to the peak summer season, park staff considered it likely a wild horse would cause an injury that needed medical attention or hospitalisation and it was also possible such an incident could be fatal.

It came after a 16-year-old boy was treated for shock and taken to hospital when he was struck in the shoulder by a feral horse as a mob galloped through a camping ground at the north side of the park in December.

According to a list of incidents seen by the ABC, that same month a family cut short their Kosciuszko holiday after their 10-year-old boy was kicked in the shoulder by a horse.

An increase in reports of horses causing havoc at the Blue Waterholes camping grounds prompted the risk assessment.

"Consideration has been given to a range of 'treatments' for managing the risk, including the closure of the campground," the risk assessment obtained through a Freedom of Information request said.

It recommended not closing the camping area immediately, given that "closure of the campground during the busy school holiday period would be very contentious. As the closure of the camp ground would be associated with the presence of wild horses it is likely to be particularly contentious".

Failing to take visitor safety seriously

An Office of Environment and Heritage spokesperson said park staff remained vigilant to the risk.

"Steps taken to date include ongoing monitoring, increased signage for visitors and increased staff patrols," the spokesperson said.

But Invasive Species Council CEO Andrew Cox, whose organisation made the FoI request, called the response inadequate and said it failed to take visitor safety seriously.

"If there's a high chance of a serious injury, then the park service should be acting, they shouldn't just simply be putting up signs," Mr Cox said.

The council has been calling on the NSW Government to end a moratorium on culling wild horses in the park since the NSW Government rejected a draft plan to reduce the brumby population by 90 per cent over 20 years last year.

In its risk assessment NPWS noted the number of wild horses was increasing with more than 250 brumbies spotted within five kilometres of the Blue Waterholes camping area in September — compared with 124 in 2010.

Mr Cox said the only thing stopping park management from taking action "seems to be current NSW government putting a moratorium on the removal of horses".

"Visitor safety should come first, but in this case it looks like government is protecting horses rather than visitors to the park."

Mr Cox said further inaction would put campers in danger during the Easter hiking season.

The Office of Environment and Heritage spokesperson said no injuries had been reported since the risk assessment.

"The safety of our visitors is a priority for NPWS," the spokesperson said.
