Darwin resident David Ciaravolo said his partner was hit when a group of teenagers were shooting fireworks at people celebrating Territory Day at Dripstone Cliffs.

"It's a bit of a tradition for us to head down there … we really love Territory Day, but unfortunately the vibe down there was absolutely terrible this year," he told ABC Radio Darwin.

"This was people hiding in bushes and attacking people with fireworks and running away and setting up and doing it again. And you honestly had no idea where they were.

"My partner copped a direct hit. Luckily she turned just in time and copped it in the back. If that was in the front, or in the face, it would have been the loss of an eye.

"She was bleeding … it's quite a nasty wound."

Mr Ciaravolo said he saw people putting fireworks under cars and lighting them towards cars, including a ute with people in the back.

NT Police Watch Commander Clinton Stewart said emergency services responded to multiple spot fires across the territory.

"The behaviour overnight has been good … We've had less fires than we've had in previous years … and people have been abiding by regulations better this year than we've had in previous years."

The NT is a bit special, isn't it?
