The boyfriend of a woman killed in a horror crash alongside three children on a rural New South Wales road has been arrested.

Tania Murphy along with two of her sons and her nephew – aged between 10 and 12 – were travelling along a remote road when their car hit a pole, flipped and landed upside down in a farming canal in Yanco near Leeton, about 550km inland of Sydney, late last night.

The 36-year-old and the three boys were killed in the crash.

Late this afternoon, two people were arrested and taken into custody

Murphy's boyfriend Dean Ingram, 32, is one of the people being questioned by police.

Police are investigating whether the pair were arguing moments before Murphy and the three children drove off.

The other person in custody is a 50-year-old woman.

The horror crash has left the Leeton community devastated.

Family members told 9News: "We're devastated, we simply can't believe they're all gone".

The family said they were in shock and what had happened still had not hit them.

Leeton Shire Mayor Tony Reneker said a feeling of "disbelief, shock and despair" is resonating throughout the town.

"It is such a tragedy to lose four people in a single-vehicle accident especially when three children are involved," he said.

"It is a ripple effect to the whole community."

Acting Assistant Police Commissioner Tracy Chapman said it was a tragic accident.

"A mother and three children have been involved in a motor vehicle collision. Our thoughts go out to their family, friends and community," she said.

The fatal crash comes as police warn drivers against driving while fatigued or under the influence over the Easter weekend.

"The message is simple: drive to the speed limit, focus on the road, not your phone, and make sure you have a plan B if you are drinking," Chapman said.

"For the last two years, we've seen seven fatalities on the road each Easter long weekend.

"The goal this year is to reduce that number."

The crash takes the road toll in NSW this year to 83.

Jacinda Ardern’s last moments in Parliament sought to reclaim her legacy.

Book Depository, a popular online bookstore that has been owned by Amazon since 2011, will close down later this month.

The UK-based retailer, which has a fulfilment centre in Australia, confirmed the news in the early hours of Wednesday morning (Sydney time), saying it will close on April 26 but that support for orders will last until June.

"We are sorry to let you know that Book Depository will be closing on 26 April 2023," it said.

"You can still place orders until midday (12pm BST) on 26 April and we will continue to deliver your purchases and provide support for any order issues until 23 June 2023.

"From all of us at Book Depository we want to say 'thank you'. Delivering your favourite reads to you since 2007 has been a pleasure."

The store had around 20 million different titles for sale and offered free worldwide shipping on all orders as part of its vision to "improving range, access and affordability of books".

Founded in the UK in 2004 by Andrew Crawford and Stuart Felton, Book Depository was bought by online retail giant Amazon in 2011.

The store's looming closure comes months after Amazon announced it would be cutting thousands of jobs from its devices and books department.

"Between the reductions we made in November and the ones we're sharing today, we plan to eliminate just over 18,000 roles," Amazon CEO Andy Jassy said in January.

"Several teams are impacted; however, the majority of role eliminations are in our Amazon Stores and PXT organizations."

It is not known how many of the 18,000 job losses impacted Book Depository.

It was anyone’s game last Saturday. What’s up this weekend ?

The Liberal Party will oppose the federal government's proposed model for a national Indigenous Voice to parliament in this year's referendum.

Opposition Leader Peter Dutton formally announced the position following a two-hour party room meeting in Canberra, saying his party's stance will improve outcomes for Indigenous communities.

"The Liberal Party resolved today to say yes to constitutional recognition for Indigenous Australians, yes to a local and regional body so we can get practical outcomes for Indigenous people on the ground," he said.

"But there was a resounding no to the prime minister's Canberra Voice."

While Dutton confirmed his party will support constitutional recognition at the same time as opposing the Voice, he said the Liberals will not ask the government to split the two proposals into separate questions in the referendum, meaning Australians will only be given the option of voting on the Voice question.

Dutton also confirmed he will actively campaign for the no vote, saying he doesn't think the Voice "is in our country's best interests".

Rather than supporting the government's proposed model of a constitutionally enshrined Voice, the Liberals will instead argue for a legislated approach for local and regional bodies.

Deputy Liberal leader Susan Ley and Dutton both claimed the government was being divisive with its approach to the referendum.

"The onus is on the government to demonstrate how Anthony Albanese's Voice proposal can improve the lives of Indigenous Australians, without dividing Australians," Ley said.

The Voice was not first proposed by Prime Minister Albanese – it was called for six years ago in the Uluru Statement from the Heart, a petition from Indigenous leaders that argued for the body's establishment to give First Nations peoples better representation.

The statement explicitly calls for the body to be "enshrined in the Constitution", rather than legislated.

In line with its policy, the Liberal position is not binding on backbenchers, who will be able to take their own stance.

However, it differs from the party's approach to both the 1999 referendum and 2016 plebiscite on same-sex marriage, when frontbenchers were also allowed to take their own position.

Dutton said the Liberals will support the legislation for the referendum before the parliament, but criticised Albanese for changing the wording of the question to be asked of Australians, claiming the prime minister had gone against the advice of the attorney-general and solicitor-general.

Albanese had previously called on Dutton and the opposition to support the yes vote for the referendum, which is likely to be held between October and December.

The Nationals, the Liberals' junior Coalition partner, announced last year they will be opposing the Voice.

Thousands of tradies have gathered in Australia's biggest cities to demand wage increases amid Australia's cost-of-living crisis.

Protesters walked off the job in Melbourne, Sydney, Canberra, Adelaide, Perth, Cairns and Brisbane, calling for salaries to increase in line with inflation.

The mass demonstration outside the Trades Hall on Victoria Street in Melbourne this morning came just five days after the collapse of construction giant Porter Davis Homes, but was reportedly organised before the company's downfall.

Union boss John Setka was met with cheers today by members of CFMEU.

"Everything we have fought for is for you to enjoy the 36-hour week," he said.

"We will fight all the way to the end."

The protesting tradies, many of which are wearing trade union CFMEU shirts and carrying CFMEU flags, demanded the Fair Work ombudsman be strengthened and replaced to avoid companies collapsing as Porter Davis has while they march to the Fair Work Commission on Exhibition Street.

"The Fair Work Ombudsman has been a dismal failure on wage theft, sham contracting and corporate insolvencies – three of the biggest issues in the construction industry," CFMEU National Secretary Zach Smith said in a statement about the protest.

"We are in the midst of the most serious cost-of-living crisis in decades while corporate greed pours petrol on an inflationary bonfire."

The action follows a rise in vandalism at construction sites by suspected out-of-pocket tradies after the collapse of Porter Davis.

A family's Porter Davis home was set on fire in Melbourne's south-east on Monday in what has been alleged as an act of vandalism by a disgruntled tradie.

Police attended the protest but there have been no reported issues with the crowd's behaviour.
