Ahead of Tuesday's productivity roundtable, the Treasury advice reportedly showed a list of proposals to be reviewed by cabinet after the meeting of business, union and other leaders.
Among them were proposals to speed up approval times for housing and reduce environmental red tape, according to the ABC.
But Prime Minister Anthony Albanese denied the result of the summit had been locked in before it began.
"You'd expect Treasury to be giving advice about a forum that's about the economy," he told reporters in Brisbane on Thursday.
"Next week, though, is an opportunity for people to advance their ideas, to advance policies, and that's a really constructive thing."
The government has already ruled out major changes in some areas, including tax policies, ahead of the three-day summit despite calls for widespread reform to bolster the country's lagging productivity rates.
The prime minister said the government was up for a range of reforms stemming from the summit.
"There'll be some things that are put forward that can be done immediately, some things can be the result of legislation, some things will feed into next year's budget," he said.
Treasurer Jim Chalmers also dismissed concerns the summit's outcomes had been pre-empted.
"Those that have been reported today are just a few of the many ideas which have been put to us and they're all welcome on the table," he said.
Opposition Leader Sussan Ley said the coalition would examine suggestions from the roundtable, but it had concerns about how the event was being handled.
"I wonder whether people who are attending this roundtable are indeed wasting their time," she said.
"What we won't do is accept an agenda that raises taxes on hardworking Australians, particularly because that's exactly what the government promised it would not do."
The leak came as the Productivity Commission released its final report ahead of the summit, calling for sweeping reforms for Australia's care system.
The body called for a national screening system for care workers, greater collaboration between health services and a major shift towards preventive health investment.
Commissioner Alison Roberts said care was a rapidly growing sector and proposed reforms would seek to break through the government's siloed approach to decision-making.
The interim report urges the government to better align quality and safety regulations across the care economy.
That could include a streamlined national clearance process for workers in aged care, the NDIS, veterans' care and the early childhood education sector.
Such a system would make it easier for workers to move between care sectors and cut down on paperwork from providers.Â
"We don't have a joined up system, which means people can move from state to state or within the sector to another (workforce) and avoid detection," Dr Roberts said.
"Greater oversight and joined up systems will reduce this risk of occurring."
The interim report also recommends the establishment of a national framework to support investment in prevention.
