Coalition's primary vote at 36% new poll shows

PRIME Minister Tony Abbott has deflected internal Coalition criticism of his government's first budget, despite poll results on Monday showing voter support for the government has not budged.

The Newspoll published on Monday showed the Coalition's primary vote remained at 36%, while Labor fell from 38% to 37% and independents including the Palmer United Party were steady on 15%.

Despite a series of gaffes on the budget details in recent days, Mr Abbott told ABC Radio on Monday he was confident the public knew "we cannot go on like we did over the last six years".

The poll also follows some disquiet about budget cuts in recent weeks, which has largely been quelled by Mr Abbott urging the government to stay the course on selling the budget.

It also recorded a 3% lift in Mr Abbott's personal approval rating, with a 5% drop in Labor leader Bill Shorten's approval rating.
