Canberra's voters are being subjected to a scare campaign on superannuation by both major parties in the federal election.
The Liberals' advertising will say Labor cannot be trusted to leave super alone, while Labor says a Coalition government would not make employers increase their contributions for their workers' superannuation.
Coalition frontbencher Mathias Cormann said on Wednesday the Labor government had promised no changes but later cut concessional contribution caps.
''Labor is at it again, promising no change … Labor's promises on superannuation, like on so many other issues, are hollow, they can't be trusted,'' Senator Cormann said.
The Labor member for Fraser, Andrew Leigh, said: "If the Coalition is elected, superannuation will cease increasing and the tax rate for low-income superannuation contributions will go up.''
