Prime Minister Anthony Albanese is warning the nation should prepare for a treacherous wet season as he visits the flooded NSW town of Forbes, where people are dealing with the fifth inundation in 12 years.

Thousands of people in the flood-prone central western town have been impacted, with some evacuated on Friday after the Lachlan River burst its banks, inundating the city centre.

Mr Albanese travelled to the flood zone on Monday, alongside NSW Premier Dominic Perrottet as major flood warnings remain in place for almost a dozen rivers across the state.

"We are living in very dangerous times in the days and weeks ahead," he said.

Relentless rain in western NSW, Victoria and Tasmania is likely to continue to cause flooding in the coming weeks, the prime minister says.

He urged people to follow warnings from emergency services, adding too many were dismissing advice to evacuate.

"(People are) saying 'no, we'll be right'," Mr Albanese said.

That attitude was leading to multiple rescues in flooded regions, putting emergency personnel at risk, he said.

Mr Perrottet said the people of Forbes were resilient, having endured five floods in the past 12 years, and reiterated that danger still loomed.

"We know over the coming week, particularly heading into summer as well, we expect more challenging weather," he said.

"We need to keep vigilant. We need to follow the instructions.

"If it's flooded, forget it. You wouldn't drive through into a bushfire - don't drive through floodwaters."

Major flooding is expected at Echuca in Victoria and Moama, a border town in the NSW Riverina district, with water rises likely to be as bad or worse than the 1993 flood - the area's second-biggest on record.

In Moama, some 200 residents of an Indigenous community are being evacuated, along with residents of the Moama caravan park.

Despite clear skies on the weekend in NSW, the Bureau of Meteorology's Dean Narramore says floodwaters are still rising.

Flood warnings were continuing across inland NSW and northern Victoria, he told the ABC on Monday.

"Today, we're going to see a number of locations peak," he said.

Major flooding at Warren, west of Dubbo, is expected to continue and more rain could cause further rises on the Macquarie River, threatening more severe flooding at Wellington and Narromine in the coming days.

People in South West Narrandera were ordered to evacuate before 6pm on Sunday after the Murrumbidgee River's main flood peak passed through Wagga Wagga last week and headed downstream.

Moderate flooding is expected downstream at Darlington Point from Thursday.

The Murrumbidgee has passed the minor flood level at Balranald while major flooding is not expected to reach the town of Hay until late October, the BOM says.

Another storm system is forecast to develop over central Australia on Tuesday, bringing widespread falls of 25 to 50 millimetres over much of inland NSW and thunderstorms to eastern states by mid-week.

"This is a lot less than what we saw, but with everything now so wet and saturated, this is going to lead to renewed river level rises on many of our already flooded rivers - particularly as we get in towards that Thursday and Friday," Mr Narramore said.

The NSW casino regulator has suspended the gaming licence of Star Entertainment's Sydney casino and slapped the embattled company with a record $100 million fine for compliance failures.

Independent Casino Commission Chief Commissioner Philip Crawford announced the hefty penalty on Monday saying the entertainment venue at Pyrmont could remain open without gaming.

"We've decided to impose a fine of $100 million on The Star, and secondly, to suspend the Star's casino licence," he said.

The suspension is effective from 9am on Friday.

The ICC last month released a scathing report, which found The Star was unfit to hold a casino licence after an inquiry identified a litany of issues - including a notorious gang-linked junket operator running an illicit cage at the casino and that it broke rules on Chinese debit cards.

"The Star Casino will remain open and all staff will remain employed," Mr Crawford said.

"The Star's licence is suspended and the manager will hold a casino licence."

Mr Crawford said he was not satisfied with Star's reform plan.

"The remediation plan contained in the Star's submission did not make much sense without the leadership of a competent and experienced CEO," he said.

"Star's new CEO, Robbie Cooke, commences at Star today. We have met with Mr Cook and he presents to us as someone who is absolutely capable of providing the strong leadership needed at the Star."

Mr Cooke has vowed to rehabilitate the embattled gambling and entertainment company.

"We need to be putting compliance at the top of the list and if you do that, it protects shareholder value," he told AAP last week.

"There's definitely some challenges in the business," he said.

Mr Cooke vowed that "compliance will be put ahead of profits" under his leadership, adding that "cultural change won't happen overnight".

"My big focus to deal with those issues is my commitment to our regulators, to our government partners, to our 75,000 shareholders, 8000 team members and the community at large to rebuild trust."

Treasurer Jim Chalmers has labelled reports the Medicare system is being rorted by up to $8 billion a year as atrocious.

The comments come after a joint ABC and Nine newspapers investigation revealed some practitioners were ripping off the system and charging for services that were never delivered.

According to the report, some doctors have been billing dead people and falsifying patient medical records to lift their incomes. Others were making mistakes on claims.

Dr Chalmers said the government was investigating the allegations.

"If these numbers are true, it's absolutely atrocious. Every dollar rorted, whether it's from Medicare or the NDIS, is a dollar thieved from people who need and deserve good health care," he told reporters in Canberra on Monday.

"If you're stealing from Medicare or the NDIS, you're a grub. It means that money that's not exactly thick on the ground in the budget is not going to people who need it."

Dr Chalmers wants a crackdown on people who rort the Medicare system, describing the report as very troubling.

"(It is) something that we will get to the bottom of because we don't want to see a single dollar rorted or thieved from the system when it could go to helping people who are vulnerable," he said.

Government Services Minister Bill Shorten said while the "vast majority" of general practitioners did the right thing, payment integrity was a problem.

"It drives taxpayers to despair if they think that some people are opportunistically rorting the system," he told Nine's Today show on Monday.

"Crooks do leave footprints ... obviously we have got to make sure there is complete confidence in the system but we need to put the crooks on notice that 'you will get caught'."

Environment Minister Tanya Plibersek, a former health minister, told Seven's Sunrise program the report was shocking.

"We need to come down on these people like a tonne of bricks because Australians feel protective of Medicare and they want to keep Medicare and they love the way our health system works, but it cannot work if you have people ripping it off," she said.

Australia has an "ambitious" new 10-year plan aiming to end violence against women and children within one generation.

The decade-long plan for 2022 to 2032 was unveiled by the federal government on Monday.

It's the second national plan aimed at ending domestic violence after then-prime minister Julia Gillard released the first one in 2010.

The updated plan aims to engage with men and boys and create respectful relationships at all ages, while it will also target sexual violence in all settings.

Women's Safety Minister Amanda Rishworth said the national plan could be broken down into four key planks - prevention, early intervention, response and healing and recovery.

"We know if we don't focus on these areas equally, then we won't see an end to violence against women and children," she told reporters.

"Holding those that choose to use violence against women and children to account is critically important ... it shouldn't be left to the victim-survivors to explain or feel shame when it comes to violence against women and children."

Ms Rishworth said there needed to be a change in conversations surrounding domestic and family violence.

"How often do you hear, for example, people say 'why didn't she leave?' I mean, the more important question is, why does he choose to use violence against her?" she said.

"We do need to promote more respectful relationships. We do need to actually increase gender equality. All of these things play a role in actually addressing violence against women and children."

Statistics show one woman dies at the hands of her former or current partner in Australia every 10 days.

One in three women has experienced physical violence and one in five has suffered sexual violence.

The national plan will also focus on how gender inequality drives violence against women.

The Australian Human Rights Commission welcomed the plan and called for all levels of government to commit the necessary funds.

"It's encouraging all Australian governments have backed the plan and its ambitious target to end gender-based violence within a generation," National Sex Discrimination Commissioner Kate Jenkins said.

"For this to succeed, all governments will need to make significant investments in prevention and recovery strategies."

NT minister for prevention of domestic, family and sexual violence Kate Worden said the plan's focus on protecting Indigenous women was vital.

"In the Northern Territory, Aboriginal and Torres Strait Islander women are 18 times more likely to be the victims of domestic and sexual violence," she told reporters.

"They are also 40 times more likely to end up in hospital as a result of that violence ... we really welcome that new focus."
