Fish kills are defined by the NSW Department of Primary Industries as a sudden mass mortality of wild fish.

"Fish kills can occur at any time although data indicates fish kills are more likely to occur in summer or following sudden changes in temperature," the department said on its website.

It's not yet known what has caused the fish kill but expert Joy Becker, an associate head of research at the School of Life and Environmental Sciences at the University of Sydney, said there were several possible factors.

"We need to let the fish kill investigation get underway to determine the cause," she said.

"This will help prevent and manage future scenarios that have a high likelihood of a fish kill occurring.

"Ultimately, fish kill events happen because the quality of the environment cannot sustain fish life.

"Causes of fish kills can be environmental, chemical, or possibly related to infectious disease agents including opportunistic pathogens or a combination of all these factors.

"When the water quality drops as is the case in blackwater events, it compromises fish physiology and if the drop is too sudden, too severe and/or too prolonged, this will lead to death.

"Complicating factors in blackwater events like disease can exacerbate situations of poor environmental conditions to cause major fish kills.

"It is important to remember that fish kill events impact not only the large body fish like the Murray cod and bony bream but also the small body fish like the gudgeons that are essential to maintaining a healthy aquatic ecosystem."

The Public Service Commissioner says the offence was at the low end of offences.

The Department of Environment, Parks and Water Security said the girl was "extremely lucky" to have escaped.

"A crocodile of that size has the potential to cause major, life-threatening injuries," the department said in a statement.

"This is a timely reminder to always Be Crocwise.

"High water levels during the wet season make it easy for crocodiles to move into areas undetected.

"Crocodiles can inhabit any body of water in the Top End."

More economists believe the Reserve Bank of Australia (RBA) will hit pause on its record-breaking run of interest rate hikes in April before resuming once more in May amid financial industry instability.

Yesterday Australia's unemployment rate fell to 3.5 per cent in the wake of a falling monthly inflation indicator, generally showing a stronger economy.

But news of Credit Suisse being forced to borrow billions to keep the doors open, along with the collapse of the Silicon Valley Bank and Signature Bank has some economists tipping that Australia's central bank will hold on its course of rate hiking.

Senior economist at AMP Australia Diana Mousina said there was "some chance" that Governor Philip Lowe and the board would hike rates in April, but they were not expecting it.

"Panic in markets over the past week around the risks to bank liquidity after the collapse of three regional US lenders and current worries around Europe's Credit Suisse bank shows that impacts of central banks rate hikes are increasing financial stability risks given the fast upward moves in rates over the past year and contagion risks remain high for now," Mousina wrote.

"Additionally, we think the February retail and inflation data in two week's time will also disappoint expectations.

"Our base case is that the RBA will keep the cash rate unchanged in April at 3.6 per cent and see the central bank maintaining the cash rate at this level before the risk of rate cuts in late 2023/early 2024."

Westpac Chief Economist Bill Evans reiterated that there would likely be a pause in rate hikes in April followed by a final increase in May.

"We now expect a pause in April to be followed by a final increase of 0.25 per cent at the May meeting," he said.

"Prior to the Governor's surprisingly hawkish response to the December quarter Inflation Report where he effectively signalled consecutive rate hikes in both March and April, Westpac had expected that there would be a pause in April with a final hike in May."

Evans said Governor Philip Lowe has previously been confident about rate hikes but in March was more tentative.

In a speech following the March rate hike, Lowe noted a pause in April would be considered depending on business surveys, the February unemployment data, the February inflation data and retail sales.

Evans believes rates will tighten to 3.85 per cent by May after previously forecasting a 4.1 per cent cash rate.

Currently the cash rate target of 3.6 per cent is the highest since May 2012, after the RBA hiked interest rates for 10 consecutive meetings.

Governor Lowe cited persistent inflation – currently sitting above 7 per cent – as the primary driver of the bank's decision to continue lifting rates.

The RBA has consistently said it intends to return inflation to between 2 and 3 per cent.

More than 40 years ago, Roxlyn Bowie disappeared, leaving behind only a letter to the family she purportedly abandoned.

But on Friday, her now 72-year-old husband John Douglas Bowie was told he would likely spend the rest of his life behind bars for killing the 31-year-old after manipulating her into writing the callous message.

Bowie was sentenced to a maximum of 24 years in prison with the possibility of parole in 2037.

In October, a jury found Bowie guilty of murdering his then 31-year-old wife in the northern NSW town of Walgett on or around June 5, 1982.

Bowie has always denied his involvement in the disappearance, but Justice Dina Yehia was satisfied he killed his wife in order to seek a sexual relationship with a younger woman.

"He is now 72 and he will not be eligible for release for some time," she told the NSW Supreme Court on Friday.

"He may die in custody."

As Yehia handed down the sentence, Bowie sat in the courtroom, red-faced and with a hand over his mouth.

Meanwhile, Bowie's sister Christine Maddocks and daughter Brenda Boyd burst into tears.

"I'd prefer to have 24 years of Roxlyn than 24 years of John being locked up," Ms Maddocks told AAP.

"This kind of thing just consumes your whole life and it's no closure for Brenda."

Boyd has spent most her life looking for her mother after the devoted carer disappeared when her daughter was six, leaving behind only a letter.

The "Dear John" letter, which was in Mrs Bowie's handwriting, said she was leaving her husband and her kids and told them expressly not to contact her.

In a subsequent letter addressed to her parents, she stated: "Please don't be hard on John, it wasn't his fault".

Her body has never been found.

Yehia was satisfied Bowie coerced his victim to write those letters before he killed her so he could "lay the claim that she simply abandoned him and the children" and move closer to his mistress in Sydney.

Prior to her death, Mrs Bowie was a loving mother who was doing the best she could in a relationship with a man who was a self-admitted womaniser and heavy drinker.

Yehia said this meant it was unlikely she had abandoned her children just because she'd had enough of her relationship with her husband.

She could not determine exactly when Bowie manipulated his wife into writing the letters or whether she had been murdered in their Walgett home, but the judge was satisfied he planned the killing and disposed of her body.

The court heard Bowie had grown up in an unstable household, often witnessing physical violence between his mother and father, and had a history of violent acts against women.

He spent most of his life plagued by alcohol dependency and suffered from several mental and physical ailments.

Bowie was arrested for his wife's murder in 2019 and will not be eligible for parole until October 2037.

A rare and giant species of spider only found in a regional part of Queensland has been discovered.

The Euoplos dignitas is a large trapdoor spider that lives in open woodland habitats and builds burrows in the black soils of the Brigalow Belt in Central Queensland.

Scientists at the Queensland Museum have given the new species a name to pay tribute to its large size.

"The name Euoplos dignitas is derived from the Latin dignitas meaning dignity or greatness and is reflected by the impressive size and nature of the spider," Dr Michael Rix said.

"This species is known from only a very few locations around Eidsvold and Monto in Central Queensland and has lost much of its habitat to land clearing, which makes it likely to be an endangered species."

The discovery comes after work by Queensland Museum scientists as part of Project DIG to find and document new species in the state.

"This new spider species is a great example of Queensland Museum's ground-breaking research," the state's arts minister Leeanne Enoch said.

The new species has now been published in the Journal of Arachnology.
