A "very concerning" increase in eating disorders among young people is among the issues expected to be investigated by an inquiry into Queensland's mental health services.

The parliamentary review will look at how the health system is coping with increased demand from the pandemic, as well as a general assessment amid reportedly high presentations.

"We are seeing an increase in eating disorders, particularly around our young people that is very, very concerning, and we're seeing this nationally," Health Minister Yvette D'Ath told state parliament on Tuesday.

Heath ministers nationwide have written to the federal government regarding the need for "urgent investment" in the mental health space, she says.

"We need to shine a light on mental health and better understand the needs and demand pressures arising from COVID, but also more generally across the mental health system in Queensland," Ms D'Ath said.

"We are confident that our parliament can play an important role in shaping the future of our mental health services in Queensland."

The health and environment committee will conduct the inquiry, which also comes amid reports the health system is being overwhelmed by mental health patients.

Ms D'Ath said 70 per cent of GP presentations in 2021 had been related to mental health, up from 61 per cent in 2017.

The health minister also said 10 per cent of the state's population had received Medicare-supported mental health care in 2019/20, almost twice the rate as any of the previous 10 years,

Queensland Health also provided specialist clinical mental health care to 2.2 per cent of the state's population in 2019/20.

The state opposition says the inquiry "must be genuine" and deliver solutions to what it is calling a crisis.

"On this Government's watch, our mental health services are crumbling despite the dedication of overworked frontline staff," opposition health spokeswoman Ros Bates said on Tuesday.

Federal parliament has been asked to acknowledge publicly the harm caused by bullying and sexual misconduct at the apex of Australian politics.

One-third of people working in Canberra's parliamentary precinct and electoral offices report being sexually harassed on the job.

"It is a man's world and you are reminded of it every day," one person told Sex Discrimination Commissioner Kate Jenkins' review of parliament's workplace culture.

"Thanks to the looks up and down you get, to the representation in the parliamentary chambers, to the preferential treatment politicians give senior male journalists."

Ms Jenkins made 28 recommendations including a public acknowledgement by parliamentary leaders and department heads of the harm caused by bullying, and sexual harassment and assault.

It also calls for targets for gender diversity among parliamentarians, codes of conduct for MPs, senators and their staff members as well as an independent standards commission.

"I'm deeply grateful to each of the people who engaged with us. It is a privilege to have been trusted by you," Ms Jenkins told reporters in Sydney on Tuesday.

"Many people shared distressing experiences of bullying, sexual harassment and sexual assault, sometimes for the first time. They said these things could never be shared with anyone else."

Former Liberal staffer Brittany Higgins was a catalyst for the review when she went public in February about her alleged 2019 rape in a minister's office by a colleague.

"I do thank her for standing up and speaking up. Her voice has been listened to," Prime Minister Scott Morrison said.

Current and former politicians and staffers were among 1723 people, mostly women, who contributed to the review that involved nearly 500 interviews.

One person spoke about aspiring male politicians who thought nothing of "picking you up, kissing you on the lips, lifting you up, touching you".

"Pats on the bottom, comments about appearance, you know, the usual ... the culture allowed it," they said.

Another detailed how an MP sitting beside them leaned over "grabbed me and stuck his tongue down my throat"

"The others all laughed. It was revolting and humiliating."

Three-in-four people in commonwealth parliamentary workplaces have experienced, witnessed or heard about bullying, sexual harassment or assault.

About half of the recent sexual harassment incidents canvassed by the review occurred at Parliament House itself.

Mr Morrison said workplace stress was "no excuse whatsoever to normalise inappropriate, unhealthy and unprofessional behaviour".

A man's world. The most sexist workplace. Somewhere women felt lucky if they were not sexually harassed.

That's the damning picture painted of federal parliament.

One-third of people working in Parliament House and federal politicians' offices reported being sexually harassed on the job. But only 11 per cent reported it.

About a quarter of people said they were harassed by a parliamentarian.

"It is a man's world and you are reminded of it every day," one person told Sex Discrimination Commissioner Kate Jenkins' review of parliament's workplace culture.

"Thanks to the looks up and down you get, to the representation in the parliamentary chambers, to the preferential treatment politicians give senior male journalists."

Federal parliament has been asked to provide a public statement acknowledging the harm caused by bullying, sexual harassment and assault as well as the lack of action taken in the past to stop it.

"I do often describe Parliament House as the most sexist place I've worked," someone else told the report, titled Set the Standard.

"There is a workplace culture of drinking. There's not a lot of accountability. The boys are lads. And that behaviour is celebrated."

Ms Jenkins' report made 28 recommendations including for gender targets among politicians and an independent commission to oversee parliamentary standards.

"Women we spoke to told us they felt lucky when they had not directly experienced sexual harassment or sexual assault," the commissioner said in Sydney on Tuesday.

"Many people shared distressing experiences of bullying, sexual harassment and sexual assault, sometimes for the first time. They said these things could never be shared with anyone else."

The review was sparked by former Liberal staffer Brittany Higgins going public in February about her alleged 2019 rape by a colleague in a minister's office.

"I want to thank the many brave people who shared their stories which contributed to this review," she said, calling for its findings to be implemented in full.

Prime Minister Scott Morrison thanked Ms Higgins for speaking up.

He believed Parliament House was safer now than it had been at the start of the year.

The prime minister also stressed there was "no excuse whatsoever to normalise inappropriate, unhealthy and unprofessional behaviour".

Current and former politicians and staffers were among 1723 people, the majority of them women, who contributed to the review that conducted nearly 500 interviews.

Three-quarters of people in commonwealth parliamentary workplaces have experienced, witnessed or heard about bullying, and actual or attempted sexual harassment and assault.

"It was just a pride to be able to work there because to me, that's the ultimate place of public service," one person said.

"And can I tell you, when I left there ... I would never, ever set foot in the place again."

Thirty-seven per cent of people have been bullied. About one per cent have been sexually assaulted or had someone try and assault them.

Someone detailed how women took fake binders to committee meetings so male MPs wouldn't try and kiss them.

"I've had colleagues caressed by senators in committee meetings in front of lots of people," they said.

Another person explained how an MP sitting beside them "grabbed me and stuck his tongue down my throat".

"The others all laughed. It was revolting and humiliating."

Ms Jenkins is confident things will change at the apex of Australian politics because community demands it.

"There's no question that the Australian community is saying: 'Actually, you should be the model and the example'," she said.

It's likely a woman who has been circulating in Sydney and on the NSW Central Coast is the fifth person in NSW to have contracted the Omicron variant of COVID-19.

Initial testing strongly indicates one more overseas traveller, who arrived in Sydney on Thursday and is isolating at home on the Central Coast, has been infected with the Omicron variant, NSW Health said on Tuesday.

If confirmed, if will bring the total number of confirmed cases of Omicron in NSW to five.

The fully vaccinated woman in her 30s arrived in Sydney on flight QR908 from Doha before the 14 days compulsory quarantine was introduced for travellers from southern Africa, and travelled by private car to the Central Coast.

NSW Health is contacting all passengers and crew on her flight to advise them they are close contacts and will need to get tested and isolate for 14 days, regardless of their vaccination status.

NSW Health has listed numerous shops in Parramatta and Top Ryde, as well as shops and two fast-food outlets on the Central Coast, that were visited by the woman before travellers from southern Africa were directed to go into isolation.

Anyone who attended those venues at the times and dates listed is a casual contact and must immediately get tested and isolate until a negative result is received.

They should continue to monitor for symptoms and if any symptoms occur, get tested again.

NSW Health says initial testing on a second person who arrived on the same flight and is now in Broken Hill indicates they are unlikely to have been infected with the Omicron variant.

The person, who is fully vaccinated and asymptomatic, is isolating at home.

Health Minister Brad Hazzard said the woman "came in before the new arrangements ... so she has been out in the community and (NSW) Health is now investigating that".

"She has essentially been out in the Central Coast area," he told Seven News.

Two overseas travellers were diagnosed on Monday with the Omicron COVID-19 variant after they arrived in Sydney on Sunday from southern Africa on Singapore Airlines flight SQ211.

They are fully vaccinated and isolating in the Special Health Accommodation.

NSW Health is contacting all the passengers on that flight to advise they are close contacts and will need to get tested immediately and isolate for 14 days, regardless of their vaccination status.

Another international traveller, who is isolating at home in Sydney after arriving on a flight from southern Africa last Tuesday, has tested positive for the Delta variant.

This person also travelled to Melbourne on flight VA800, departing at 6am on Thursday and returned to Sydney on flight QF486, which left Melbourne at 7pm that evening.

Passengers in the surrounding seats on flight VA800 from Melbourne to Sydney have been deemed close contacts and all other passengers and air crew are casual contacts.

NSW recorded 179 new cases of COVID-19 and there were three COVID deaths recorded in the 24 hours until 8pm on Monday, ending a four-day run of zero deaths.

The latest COVID deaths include a western Sydney man in his 40s with underlying health conditions who died at Nepean Hospital.

A man in his 50s died at Tamworth Base Hospital and a woman in her 60s died at St Vincent's Hospital.

NSW Health said 62,166 tests were conducted in the past day.

Some 94.5 per cent of people aged 16 and older have had one dose of a COVID-19 vaccine, while 92.4 per cent are fully jabbed.

More than 81 per cent of teens aged 12-15 have had one dose of a vaccine, while 76.5 per cent of them have had two doses.

There are 160 people in hospital with COVID-19, 26 are in ICU and 11 are ventilated.
