One person has been injured after a light aircraft crashed on a beach in central Broome, police say.

The plane crashed into shallow waters at Roebuck Bay, at about 11:25am, according to witnesses. 

Police said one person sustained non-life-threatening injuries.

The ABC understands there were four people on board, and the plane had taken off from Broome Airport shortly before it crashed.

Emergency services are at the scene, including marine rescue, police and St John ambulance, police said. 

Plane was ‘dipping quite low’

Witness Alex MacNamara was on the town jetty and described seeing the plane flying low, shortly before it disappeared into the mangroves.

“I saw it flying and then dipping quite low, and then I just assumed it had passed over the horizon … it was just a bit past the mangroves,” she said.

“It looked like it was doing a sort of turn on an angle and then it was just dipping quite low.

“It just looked like they [emergency services] were coordinating things from the shore; they had their walkie-talkies and some sort of satellite thing.”

Erica Gunyan also saw the plane go down while she was at Town Beach.

She said she felt nervous watching the aircraft.

Roebuck Bay is a long curve of coast fringed by thick mangroves, popular among locals and tourists for fishing and boating.
