Voter support for the federal government has risen by three percentage points in three weeks, according to the latest Newspoll.
The poll comes head of parliament sitting on Monday for the final sitting weeks ahead of the budget due on May 9.
It shows Prime Minister Malcolm Turnbull's coalition is sitting on 48 per cent of the two-party preferred vote against Labor's 52 per cent.
That's higher from the February poll, which showed the coalition on 45 per cent and Labor on 55 per cent.
The bump in the government's fortunes is being linked to its announcement last week of a $2 billion expansion of the Snowy Mountains power scheme.

Meanwhile, the coalition's primary vote has grown from 34 per cent to 37 per cent, while Labor's has dropped from 37 per cent to 35 per cent.
On the preferred prime minister measure Mr Turnbull remains more popular than Labor opposition leader Bill Shorten, at 43 per cent to 29 per cent respectively.
The Newspoll of 1819 voters, taken between Thursday and Saturday and published in The Australian, also shows primary voting support for One Nation remains at 10 per cent, despite the fallout from the West Australian election which saw that state's coalition government lose to Labor.
The Australian Greens, in contrast, were down one percentage point to nine per cent.
