The Queensland premier admits there is a "blurring" in lobbyist rules after a firm was granted a government contract without a tender weeks after making a donation to the Labor party.
Labor-aligned Anacta Strategies made a $35,000 donation to party on February 15 and a day later its representative Denise Spinks had a private meeting with Energy Minister Mick de Brenni.
Government renewable energy firm CleanCo last month awarded Anacta a contract worth up to $75,000 to train staff in government and stakeholder relations.
Under a government policy, political staffers can't hold business meetings with state representatives on matters related to their former roles for 18 months after they depart.
Premier Annastacia Palaszczuk said she had been advised that Mr de Brenni's meeting with Ms Spinks "was not a business meeting".
She then told journalists to put questions to the minister if they wanted more detail.
When asked if she thought it was appropriate for lobbyists to donate to Labor, the premier said a parliamentary committee was probing former bureaucrat Kevin Yearbury's report into reforming integrity.
"There were recommendations around lobbyists, and you know if we want to, if we need to, tighten our rules, we will do so," Ms Palaszczuk told reporters on Thursday.
"There is a blurring at the moment of people who are either ... working for in-house legal firms, for people who are (in) government relations.
"And these are issues that will be looked at in the context of that review, and the committee.
Liberal National Party leader David Crisafulli said a $75,000 contract for a government-owned firm to get advice form a known Labor lobbying firm on how to deal with the government was "pretty good deal if you can get it".
"So $75,000 - $40,000 goes to the Labor lobbyists, $35,000 goes to the Labor Party, and the only person who loses is the Queensland taxpayer," he told reporters.
"Which is what happens when governments give up on integrity over and over and over again."
Mr Crisafulli accused the government of using Anacta to "quite frankly wash money" for Labor.
When asked if he was alleging money laundering, he said, "Well, it smells".
Anacta director David Nelson rejected the allegations, saying his company had complied will all donations and lobbyist laws.
"Mr Crisafulli's comments today are defamatory and political muckraking at its absolute worst," he told AAP.
"If the LNP had any shred of evidence of wrongdoing on our behalf they would've referred it to the ECQ, but they haven't.
"We already wrote to the ECQ to look into the LNP's cooked claims and they found no issues with our donations."
When asked if he would refer Mr de Brenni and Anacta to the ECQ, Mr Crisafulli said he would "reflect on it".
However, LNP leader insisted the only way to deal with issues was a commission of inquiry into state government integrity.
Ms Palaszczuk has been facing a string of integrity questions this year, mostly related to Integrity Commission Nikola Stepanov, who will finish in her role in July.
The Crime and Corruption Commission (CCC) is investigating a series of complaints made by Dr Stepanov about senior public servants.
Her most serious claim is that Public Service Commission (PSC) staff seized a laptop from her office and wiped it in March 2021 without her knowledge or permission.
