Two of the government's biggest calls of the last two months have found favour with voters, polling from Essential Research shows, while there is surprising scepticism about the Coalition's commitment to fiscal rigour.

Almost half -- 48% -- of voters approve of the Prime Minister identifying the September election date so far in advance, including 15% who "strongly approve", with 34% disapproving. Responses split along partisan lines, with Labor voters overwhelmingly approving and Liberal voters least likely to approve; but even 35% of Liberal voters approved compared to 50% who did not.
