Some of Prime Minister Malcolm Turnbull's closest advisers have been drawn into a heated shouting match with a local Greens protester during a campaign stop on the Sunshine Coast.

Senior Turnbull confidantes Senator James McGrath and principal private secretary Sally Cray asked, respectively, who paid for the activist's unemployment benefits and how she would fund hospitals when challenged on the Adani coal mine and healthcare cuts.

"Don't want to answer the hard questions!" the protester yelled out as the Prime Minister walked ahead.

"The Adani coal mine…If it was a country, it would be the seventh highest polluter in the world. What are you going to do about that, Mr Turnbull?"
