Queensland's Liberal National Party has accused the state government of keeping people in the dark about a probe into alleged malpractice at Mackay Hospital, and broader capacity problems in the health system.
A probe of the north Queensland facility was ordered in October after complaints from women about complications from caesareans, and allegations of patient harm.
Mackay Base Hospital's accreditation to train specialist obstetricians and gynaecologists was recently suspended and at least one doctor was stood down before the investigation began.
LNP leader David Crisafulli says former patients and staff are "in limbo", with the report's release already pushed back from March to June.
"Pick a date and give the commitment that it will be released lock stock and barrel, and that people will be able to get justice and that change can be driven," the opposition leader said on Tuesday.
Mr Crisafulli said if the inquiry needs more time to gather or examine evidence, the government should explain to people what is happening.
"Be honest with people, be open and accountable, take people on the journey, explain what's happening, rather than this clandestine approach where information just isn't flowing," the LNP leader said.
He also raised concerns about the government not releasing any emergency waiting or ambulance ramping data for 2022 yet.
Health Minister Yvette D'Ath released data late last month for the December quarter of 2021 in response to a question on notice from LNP health spokeswoman Ros Bates on March 30.
"It's deeply concerning, and the government has to answer why they wouldn't share it with Queenslanders," Mr Crisafulli said.
"In other states I can see data in real time, I can see data on my phone, as to what's happening in the emergency department of the Tweed Hospital (on the NSW border) and I can't tell you what's happening over our shoulder.
"But to have information withheld for five months - information that belongs to Queenslanders, information that will help us drive change, that will help us properly resource where there is an issue, that tells me that the government is more interested in how things look than how they are."
Comment has been sought from the health minister.
