Top Liberals including the PM, senior Labor politicians, as well as Nationals, Greens, Pauline Hanson and Clive Palmer have all been caught stretching the truth during the federal election campaign, according to investigations by AAP's new FactCheck team.

Prime Minister Scott Morrison's claim that the government hadn't "changed anything for those earning on the top tax rate" was not true. AAP FactCheck found there would be benefits for highest-income earners with fewer people paying less tax.

"Based on the government's planned changes, the top tax rate remains at 45 per cent but the number of people in that bracket will change and the amount of tax they pay will change," AAP FactCheck found in its analysis.

Labor's shadow Minister for Finance Jim Chalmers also erred when he claimed "more than one-third of people who present to emergency departments are waiting longer than is clinically recommended".
