Premier Annastacia Palaszczuk has faced questions about accountability for weeks after Integrity Commissioner Nikola Stepanov announced her resignation last month.
During question time on Thursday, Liberal National Party MPs probed the government about lobbyists and donations to the Labor Party.
They focused on donations from Anacta Strategies, which is run by former Labor MP Evan Moorhead.
The treasurer rose to scold the opposition, saying they should be asking relevant questions about things like the cost of living.
"Every day the LNP comes in here and talks about things like lobbyists is another day when they demonstrate their irrelevancy," Mr Dick told parliament.
Dr Stepanov, who finishes in her role in July, has complained of interference in her office and has called for a formal Commission of Inquiry into government integrity.
The Crime and Corruption Commission is also probing her allegation that a laptop was taken from her office and wiped without permission.
The LNP claim Dr Stepanov had been probing Labor lobbyists when the laptop's contents were deleted.
Ms Palaszczuk denied lobbyists played any role in government decision-making and said they were subject to strict disclosure rules.
"As the leader of the opposition would know, our public servants provide advice to ministers, and ministers make their decisions," she told parliament.
"The leader of the opposition will also know that there are lobbyists on all different sides of politics and they must adhere to a lobbyists' code of conduct ... and they actually have to register their details."
LNP integrity spokeswoman Fiona Simpson said Anacta had donated $164,000 to Labor since 2019 and asked the premier to guarantee that it was not funnelling illegal donations on behalf of third parties.
"Those opposite know that if they have any evidence or any allegations, they can refer that to the ECQ (Electoral Commission of Queensland)," Ms Palaszczuk said.
Meanwhile, the Economics and Governance Committee remained silent about the status of the premier's referral of bullying and misconduct allegations against the integrity commissioner.
Ms Palaszczuk referred the claims against Dr Stepanov to the committee two weeks after she complained about the laptop.
The LNP has called for the committee to comment and Dr Stepanov has no objections, but the premier says there are legal restrictions.
The Economics and Governance Committee is holding a private meeting on Thursday afternoon.
