SUPPORT for the Coalition has tumbled to another dangerous low following divisive debates on company tax cuts and race-hate laws.
The latest Newspoll, conducted for The Australian, shows the government is trailing Labor by 47 to 53 per cent in two-party terms.
Prime Minister Malcolm Turnbull also lost ground to Opposition Leader Bill Shorten as preferred prime minister to lead by only 41 per cent to 32 per cent on the key leadership measure.
The survey of 1708 voters, taken from Thursday to Sunday, revealed a dip in the Coalition's primary vote from 37 per cent to 36 per cent over the past fortnight to give Labor a clear election-winning lead.
Mr Turnbull's net satisfaction rating has weakened slightly from -27 points to -29 points since the previous poll, taken on March 16-19.
According to the poll, Pauline Hanson's One Nation kept its hold on 10 per cent of voters to match support shown for the Greens.
The Newspoll comes after a tumultuous week for the government, during which the Senate approved some of its company tax cuts but voted down the proposal to scale back the Racial Discrimination Act's section 18C.
