A man has been arrested after his mother was found decapitated in a remote Northern Tablelands community in one of three alleged domestic violence-related incidents across New South Wales. 

About 9.35pm on Saturday, police were called to a property on Ironbark Road in Mole River, about 40 minutes west of Tenterfield, following reports of a domestic violence incident.

Officers were told a 37-year-old man had entered a property and attempted to steal a vehicle before assaulting the homeowner, a 74-year-old man.

They then arrested the 37-year-old before visiting a neighbouring property, where they found the body of a 70-year-old woman.

It is alleged the woman was decapitated. The man in custody is understood to be her son. 

A house on the property had also been partially damaged by fire, police said.

The case is one of three separate incidents in which women died during a 12-hour period across the state. 

In eastern Sydney, a man was charged with murder on Saturday evening after an elderly woman was allegedly stabbed to death at Bondi Beach.

NSW Police were called to a unit on Chambers Avenue in Bondi, in Sydney’s eastern suburbs, at 5.15pm on Saturday.

A woman, aged in her 90s, was found with significant injuries. She was treated at the scene, but died.

A 47-year-old man, who was known to the woman, was arrested at the home and taken to Surry Hills Police Station.

Police have set up a crime scene and launched an investigation.

Following inquiries, police charged the 47-year-old man with murder (domestic violence). 

He was refused bail and was scheduled to appear before Bail Court on Sunday.

In a third incident, a 23-year-old woman was unable to be saved on Saturday at about 11.45am.

She had been found with fatal stab wounds inside a home in Wagga Wagga, in southwest NSW.

At a unit in Bondi Beach on Saturday, just after 5pm, a 47-year-old man was arrested after an elderly woman died from significant injuries. He was charged with murder (domestic violence)

Opposition Leader Kellie Sloane said the deaths were not isolated and cited data showing a woman is killed every 11 days by an intimate partner

Officers arrested an 18-year-old man at the home and he was taken into custody for questioning before later being released without charges.

A 31-year-old man was arrested almost nine hours later at another home in the regional city and was later charged with murder, police confirmed on Sunday.

The pair were in a relationship, investigators said.

Detective Inspector Brent Falkiner added that ‘all three parties are known to each other’.

He confirmed an alleged murder weapon was located by officers.

‘We’re not looking for any other items. We believe that everything was located at the scene, inside the home,’ he said.

NSW and federal political figures responded to the incidents with horror on Sunday.

‘Three women have lost their lives in the space of one day,’ Premier Chris Minns said.

‘These are shocking crimes and families are today dealing with unimaginable grief. My thoughts are with the families and loved ones of the women who have died, and the communities affected by these events.’

Opposition Leader Kellie Sloane told reporters the deaths weren’t isolated and cited data that found a woman is killed every 11 days by an intimate partner.

‘Women of every age, from a 23-year-old to a woman in her 90s, are still not safe in their own homes,’ she said on Sunday morning, according to The Daily Telegraph.

‘I am horrified by the alleged stabbing deaths of three women in NSW on Saturday, in Wagga Wagga, Bondi, and Mole River. 

‘Police are treating these incidents as domestic and family violence related. My thoughts are with their families, friends and communities, and with the police, paramedics and neighbours who responded.’

Sloane said Australia is ‘failing women’ and demanded all levels of government take action.

Federal Social Services Minister Tanya Plibersek also stated that the women are owed ‘more than our sorrow’.

‘My thoughts are with their families and loved ones,’ she said. 

‘Every level of government, every community organisation, our schools and workplaces, every family – all of us need to work together to keep women and children safe.’

She said the Albanese government has invested $4.4billion in services to support Australians ‘but we know there is more to do’.

‘We’re finalising the Second Action Plan to redouble our efforts,’ she added. 

‘While there is one woman or child afraid in their home at night we won’t rest.’
