Julie Bishop and Tanya Plibersek are now the preferred leaders for their respective parties, according to new polling.

A survey by Roy Morgan of 552 voters, shows Ms Bishop overtaking Malcolm Turnbull as the coalition's preferred leader - leading 34 per cent to 25 per cent.

Tanya Plibersek remains well ahead of Bill Shorten as favoured Labor leader, sitting on 25 per cent ahead of Anthony Albanese on 24 per cent - with Mr Shorten unchanged on 14 per cent.

Ms Plibersek has been the preferred Labor leader in the last four polls.

Both Ms Bishop and Mr Turnbull have a sizeable lead over Tony Abbott, on 14 per cent.

But support for the former prime minister is at its highest since he lost the top job last year.

Among coalition voters Mr Turnbull is still the favourite, and Mr Shorten holds a one per cent lead over his deputy when only Labor voters are considered.
