A dirt rider says he feels lucky he was not decapitated after being clotheslined off his motorbike by a high-tensile wire strung up across a forestry road at neck height.

Ben Bird was riding on a forestry track at Amamoor, near Gympie in southeast Queensland, surveying fencing around the property he cares for, when "an invisible force" hit him, knocking him off the bike on Tuesday afternoon.

He got up to find a high-tensile wire strung up across the track between two trees about seven metres apart.

"I was pretty shocked, wondering what the hell it was," Mr Bird said.

"I thought maybe it was a branch at first … I wasn't too sure. It was like an invisible force took me off.

"I looked up and I could see the wire dangling from where I hit it.

"I took one of my gloves off instantly and there was no blood. I could move my neck and I stood up straight away. That was a relief."

Mr Bird said he was wearing his neck guard at the time, but the wire slid up underneath and got him across the neck.

The 25-year-old had just come onto the forestry track and estimated he was travelling at only 15 kilometres per hour at the time of impact.

Any faster and he fears what would have happened.

"Normally in that spot of the track it's a flat straight. I could be going up to 60-70 kph there," he said.

"The wire had been tied in a slip knot so when you hit it pulls tighter."

Mr Bird said the area was very popular on weekends for people with dirt bikes and 4WDs.

"I won't be going fast out there again, not unless I check the track first," he said.

"It puts a bit of fear in you … big time.

"Why would you want to decapitate someone? It's a bit out there.

"The way they did it too, there'd be no way to find out who did it. You wouldn't see it from any spot and you could get there easily without being seen."

'The same thing happened to me'

Mr Bird shared his story on his Facebook page on Tuesday evening as a warning for locals and was met with an overwhelming response.

In just under 24 hours a photo of the wire across the track had been shared more than 8,000 times, and attracted comments from people who have had encounters with similar traps.

"Cousin of mine ran into a single strand of barbed wire that was strung across his dirt-bike trail. He did survive and is back to riding," one person wrote.

Another said: "Same happened to me, hit me on my neck. Luckily I wasn't going too fast, and they did a shit job with the wire so it came loose on one end."



A spokeswoman for the Department of Environment and Science said they were liaising with police to investigate further.

"Rangers work closely with QPS to patrol national parks and any instances of dangerous and illegal behaviour will be dealt with," the spokeswoman said.

"It is an offence under the Forestry Regulations to do something that interferes with the health and safety of a person.

"Queensland Parks and Wildlife Service takes matters of public safety within national parks and state forests extremely seriously."
