A NSW Ambulance spokeswoman said five ambulance crews were called the scene about 8.30am on Tuesday. Police, NSW Fire and Rescue and Port Stephens SES also responded to the scene of the incident.
Officers from Port Stephens-Hunter Police District established a crime scene along Mount Hall Road.
An SES spokesperson said the unit, based in Raymond Terrace, assisted police at the scene with tarpaulins.

Speaking outside Links Drive, just off Mount Hall Road where police were stationed on Tuesday morning to direct traffic away from the crime scene, long-time Raymond Terrace resident Peter McMahon said the tragedy had "shaken everyone".
"In a small town, it's a bit of a shock for everyone. Particularly the locals," he said.
"There's a lot of nice young kids around here going to the high school.
"I've been living in this area for 20 years... You get things that happen but this is pretty much a one-off as far a fatal accident is concerned. I don't remember the last one.
"You get a lot of kids in a confined area going to school, some walking, some getting off buses. At that hour in the morning, there's bumper-to-bumper buses.
"It's very unfortunate that something like this has happened."
Port Stephens MP Kate Washington wrote on social media on Tuesday afternoon that news of the incident was devastating.
"Raymond Terrace's heart is breaking right now. My deepest condolences to family, friends, loved ones and the entire school community," she said.
