Turnbull warns MPs on inward focus

Malcolm Turnbull has warned his coalition colleagues not to talk about themselves and focus more on voters.

The prime minister was barely off the plane, returning from the Paris climate summit, when he attended the final joint partyroom meeting for the year in Canberra on Wednesday.

The government was ending the year in good shape, but "the less we talk about ourselves and the more we talk about the people who elect us, the better", Mr Turnbull said.

Next Monday's innovation statement would be "very significant", as would his talks with the premiers at the Council of Australian Governments meeting.

Mr Turnbull said the public accepted the tax system was outdated and needed reform.

But the purpose of any changes would not be to raise revenue only to spend more.

"It would be to encourage Australians to work, save and invest."
