Labor frontbencher Sam Dastyari will be surprised if Malcolm Turnbull lasts longer than 18 months, let alone a three-year parliamentary term.

In particular, the Labor senator says former Liberal leader Tony Abbott is out and about running his own campaign.

"You don't suddenly start going around the country giving speeches on the economy as a backbencher from Waringah," Senator Dastyari told Sky News on Sunday.
