The latest Newspoll gives the Coalition an 18-point lead over Labor on a two-party preferred basis.

The 59-41 result puts the Opposition at its strongest point in more than a decade and is up three points on the previous Newspoll in mid-April.

The poll of 1,150 voters taken over the weekend has a margin for error of 3 per cent.

Labor's primary vote fell two points to 27 per cent while the Coalition's primary vote is 51 per cent.
