The Northern Territory has recorded its first road fatality for the New Year, after a woman was run over by a motorbike at Alice Springs this morning.
Police say the woman was lying on the Sturt Terrace roadway at Eastside when the motorbike ran over her at about 2.30am.
She was taken to Alice Springs Hospital but died a short time later.
It was also the first road fatality of the Christmas and New Year holiday period in the Territory.
The bike rider suffered minor injuries from falling off the bike.
Police say it was a busy night in the central Australian town.
A man who asked his neighbours to keep the noise down during New Year's Eve festivities was bashed with a baseball bat.
The 48-year-old man suffered severe facial injuries and broken bones in the attack.

Two men have been arrested in relation to the assault and two women who allegedly tried to interfere with the arrests also face charges.
In an unrelated incident, two juveniles are in custody after a large group of youths set fire to a car at Yarabah Court.

On New Year's Eve, a grass fire near the Crowne Plaza in the centre of town caused the cancellation of a planned children's fireworks display.
In Darwin, police say they believe social media was to blame for a large party in the rural area that got out of control overnight.
Police were called to a property at Humpty Doo, in Darwin's rural area, where about 300 people had gathered.
Watch Commander Bob Harrison says it took police about two hours to disperse the partygoers, who threw rocks and bottles at officers and their cars.
"What we find is social media is a very useful tool for partygoers," he said.
"Once it gets on to social media, it spreads like wildfire.
"What you think is going to be a small party suddenly turns into a big party and, unfortunately, when you have got alcohol involved, young people and things, it can get out of hand really fast, as this one did in Humpty Doo."
Police say that, generally, people in the Top End capital were well-behaved in their New Year celebrations.
Paramedics say they had an uneventful New Year's Eve in Darwin and have commended revellers on their good behaviour.
St John Ambulance officer Craig Garraway says one of the most serious incidents involved a man who had to be rescued after falling from a cliff at Bynoe Harbour.
The man sustained a fractured leg but is in a stable condition in hospital.
Mr Garraway says he isn't sure why this New Year's Eve was much quieter than previous years.
"We were all standing in Mitchell Street with the police and we were all wondering why Mitchell Street was so quiet," he said.
"There were a lot of people at the casino and other areas but I'm unsure why Mitchell Street was as quiet as it was.
"But it was great for our guys because everyone was really well behaved and enjoying the night, and there were no real dramas."
