A 91-year-old woman has died and four other people injured in a dog attack in the Shoalhaven on Sunday.
The attack happened on Collingwood Beach, off Elizabeth Drive at Vincentia about 7am.
It is understood the five people were walking on the popular Jervis Bay beach when they were attacked by three dogs.
On arrival, NSW Ambulance paramedics found five people - one man and four women - suffering lacerations and bite marks.
A 91-year-old woman suffered serious injuries and died at the scene.
NSW Ambulance District Inspector Faye Stockman said the woman who died had been bitten on "both limbs and both legs", while the other victims were bitten on similar parts of the body.
Speaking on Sunday, South Coast Police District Commander Detective Superintendent Greg Moore said the other four victims were transferred to Shoalhaven Hospital.
He said they were in a serious, but stable condition.
"I take this opportunity to acknowledge the bravery and the good work by the witnesses and the emergency services at the scene that worked to contain the dogs and support the injured," he said.
Superintendent Moore said one of the other victims, aged 71, is the daughter of the woman who died.
The ages of the other victims are not yet known.
The three dogs have been seized by Shoalhaven City Council rangers.
Superintendent Moore said police had been advised that the animals involved were of cross bull mastiff breed.
He said arrangements were being made to have the animals euthanized.
Superintendent Moore also said police had begun a coronial investigation into the matter.
"In broad terms, there are criminal offences associated with offending dangerous animals or not securing dangerous animals, so that will be certainly one aspect of the investigation," he said.
He said police would be investigating how the dogs happened to be out of their owner's premises.
Superintendent Moore also reminded all dog owners that they should ensure their animals are properly secured, especially dogs of a "more vicious breed".
