After a boost yesterday with better than expected economic growth, the government was now facing problems with its proposed changes to superannuation, opposed by many in the community and some members of the coalition.
There were questions over the fairness and retrospective nature of some parts of the changes outlined in the Budget last month.
Some coalition MPs said they were receiving concerns from voters and had not been properly consulted.
Cabinet secretary Arthur Sinodinos said the coalition's plan had been to get a mandate for the policy at the July 2 election, then issue an exposure draft of legislation for consultation.
He conceded "not all individual measures" were discussed in the coalition party room as part of the briefing before the budget was handed down last month.
"I'm just leaving it open," he told Sky News when asked about the prospects of further changes being made.
Labor has yet to make its position on superannuation clear, but said parts of the policy were retrospective and could hit middle income earners rather than just the rich.
Turnbull and Opposition Leader Bill Shorten are in Sydney tomorrow.
Turnbull would continue with innovation as a central theme. Mr Shorten would also be announcing Labor's policy to drive investment in renewable energy to reduce household power costs and creating jobs.
Labor wants 50% of all energy to be renewable by 2030.
