Gold Coast coach Justin Holbrook has dismissed the suggestion his struggling NRL club has a poor off-field culture but admits Kevin Proctor's halftime vape was a bad look.

The Titans immediately cut all ties with Proctor on Monday after a now-deleted Instagram story on the forward's own page showed the veteran vaping during his team's loss to Canterbury at CommBank Stadium.

The video was uploaded with the caption "not the halftime vape", with Proctor inhaling and then shaking his head with the Titans down 26-10 at the time.

It's a sad end to Proctor's troubled stint at the Titans, whom he joined in 2017 as a big-name signing after a successful spell with Melbourne.

Proctor was axed as the club co-captain less than a year later after a cocaine scandal while in a New Zealand Test camp in Canberra, and received a four-game ban in 2020 for biting former Kiwis teammate Shaun Johnson.

Off-contract at season's end, the 33-year-old was already set to depart the Titans but that decision was brought forward in the wake of the video emerging.

"Poor KP, he's not the world's worst person. He's a decent guy but it's just a really dumb thing and gave us no choice but to obviously finish him up," Holbrook said.

Last weekend's loss to the Bulldogs was the Titans' eighth in a row, with only for-and-against keeping the club ahead of Wests Tigers and off the bottom of the ladder.

Holbrook said that situation only exacerbated the unacceptable aspect of Proctor's actions.

"It's a terrible look given where we sit the table," Holbrook said.

"People at every club are going to make poor decisions but it highlights the fact when you're not having a good year, that's for sure. It's not good."

Proctor's indiscretion, given his status as a senior player within the squad, has raised concerns about the club's culture but Holbrook was adamant this was an isolated incident and not reflective of a wider issue.

"You've got to react as quick as you can to a bad situation and put a stop to it and that's what we've done but as an overall club ... the nucleus of this side is really committed to the club doing well," he said.

"No-one's happy where we're sitting and an unfortunate action like that, as I said, highlights it and doesn't do us any favours, that's for sure."

Holbrook said he hadn't spoken to Proctor yet but would be remind players of their off-field responsibilities.

"I didn't have everyone here at once today, but yeah, everyone knows what's expected of them," he said.

"You're going to get more scrutinised ... a good example, if you're seen laughing and that where we sit, we look disrespectful.

"If Penrith do it, it's funny because they're winning and that's fact.

"So we're going to accept that and be a little more careful on how we conduct ourselves."

The Queensland government isn't necessarily being held to account by the parliament, an inquiry has heard.

The state has no upper house, so parliamentary committees act as a quasi-senate by reviewing laws and grilling the government over spending.

Clerk of Parliament Neil Laurie says reforms in 2011 improved the way proposed laws are probed but committees are falling short on scrutinising the government.

"We have a long way to go," Mr Laurie told a budget estimates hearing on Tuesday.

"I think the parliamentary committees have not necessarily been discharged in some of the things that were envisaged in the 2011 review.

"In particular, around things like public works and public accounts, and reviewing the auditor-general's reports in proper and adequate way.

"I think we have a long way to go in regards to that accountability aspect in the work of committees."

Mr Laurie said there was no magic bullet for improving scrutiny of the government but the estimates wasn't working as well as what was envisaged in 2011.

"The system that was in place prior to 2011 may, in fact, be better in some respects, because you know, things may have gotten even worse in terms of overall estimates process," he said.

"But I don't have a magic bullet and I think it's a subject to review."

Premier Annastacia Palaszczuk was being grilled on Tuesday morning, with Treasurer Cameron Dick due to face the committee later in the day.

Queensland's lobbyist watchdog has only two staff making it "quite difficult" for it to do its job properly, its acting boss says.

Tony Keyes is running the Office of the Integrity Commissioner while the government is trying to recruit a permanent successor to Dr Nikola Stepanov, who controversially left the role earlier this month.

Mr Keyes is not convinced the two staff can regulate and record lobbying, advise politicians and bureaucrats on conflicts of interest and raise public awareness on integrity.

"I have only been in the role for eight days, so it is early days," he told a budget estimates hearing on Tuesday.

"Members would be aware that the commissioner has three broad areas of functions .... My impression is two FTEs (full-time equivalents) to discharge most those functions would be quite difficult."

Meanwhile, director-general of the Department of the Premier and Cabinet Rachel Hunter revealed she hadn't heard from Professor Peter Coaldrake about an allegation he reported about a unnamed director-general.

The academic's recent accountability probe heard evidence the official prevented a report from "reaching a minister's ears" so the politician could deny knowledge of the matter.

"The premier invited Prof Coaldrake to make any representations to me (that) he would wish to make in relation to that allegation," Ms Hunter said.

"He has not done so."

Premier Annastacia Palaszczuk defended her record on integrity, saying she was planning to implement Prof Coaldrake's recommendations "lock, stock and barrel".

She said the academic will also address her entire cabinet about accountability on Monday.

"If the Leader of the Opposition would like Peter Coaldrake to come and speak to his shadow ministers, I'll be more than happy to ask him whether he'd be available to do that as well," Ms Palaszczuk told the hearing.

"The more people that are briefed by him, I think the better."

Earlier, Clerk of the Parliament Neil Laurie said the government wasn't necessarily being held to account properly during budget estimates hearings.

Queensland has no upper house, so estimates is the only opportunity for government spending to be probed.

"We have a long way to go," Mr Laurie told the hearing.

"I think the parliamentary committees have not necessarily been discharged in some of the things that were envisaged in the 2011 review.

"In particular, around things like public works and public accounts, and reviewing the auditor-general's reports in a proper and adequate way.

"I think we have a long way to go in regards to that accountability aspect in the work of committees."

A mother has been charged with the murder of her three children after they perished in a house fire in the West Australian town of Port Hedland.

A 10-year-old girl and two boys, aged seven and five months, were found dead inside the Anderson St property by firefighters who responded to the blaze on July 19.

Their mother, Margaret Dale Hawke, 36, has been charged with three counts of murder and one count of criminal damage by fire.

She has been refused bail by police and will face Perth Magistrates Court on Tuesday.

Hawke was hospitalised at Hedland Health Campus after the fire before being flown to Perth for further specialist treatment.

The blaze has sent shockwaves through the community of Port Hedland, in WA's Pilbara region.

Support services are being provided in the town by government agencies.

In a statement on Friday evening, the Hawke family said it was going through a "very traumatic grief process" and asked for their privacy to be respected.

"We are quietly paying tribute to our 3 little angels, and just supporting each other at this time," they said.

"Please let us do this without adding to our grief."
