Three people have sustained facial injuries from fireworks during celebrations in Darwin and the surrounding area last night.

Fireworks lit up much of the region as the NT celebrated the annual Territory Day, which marks the transition to self-government.

But a 34-year-old woman was burnt in the neck and face by fireworks at Nightcliff foreshore, a 47-year-old man was hit in the face at Humpty Doo and a 33-year-old man was burnt on the neck and arm at Dundee Beach.

All three were treated by St John Ambulance.

A woman working at the Palmerston McDonald's escaped injury after a firework was thrown through the window of the fast food outlet's drive-through and exploded in her face.

The Northern Territory is now the only Australian jurisdiction where the general public is allowed to let off fireworks without a special licence. Fireworks went on sale on Friday and can only be used between 6.00pm and 11.00pm on Friday.

But police say many people flouted the law on Territory Day, with 147 reported disturbances in Darwin and eight in Alice Springs.

Police were called to put out more than 207 blazes during celebrations last night - 158 of the fires were directly caused by crackers.

Senior Sergeant Michael Potts says in Alice Springs some people set off crackers outside the police station after the 11pm curfew.

"We had probably several fireworks discharged probably even outside the police station last night," he said.

'Idiot element'

District officer Dave Pettit says sky rockets caused the most problems.

"The idiot element with sky rockets really excelled last night. We had reports from people firing them from high-rise buildings down on to cars and passers-by and that's a real concern," he said.

The Darwin City Council is calling for firework zones to be introduced on Territory Day.

Lord Mayor Graham Sawyer says council crews have had a busy weekend cleaning up the rubbish left behind from fireworks and it would be easier if people where limited to letting them off only in defined places.

Councillor Sawyer says the council will review cracker night and look at ways of reducing the burden on fire crews.

"It's something that needs to be considered," he said.

"I mean we've looked at the factors around trying to restrict zones where people can let off fireworks but I think it's certainly something we should be having a look at; whether or not it's possible or feasible, I don't know."
