Support for the federal opposition has surged ahead of the government, the latest Morgan poll has found.

The coalition has overtaken the government for the first time since the federal election in August, according to the poll, published on Friday.

Support for the coalition is up four per cent since the start of December, with 51.5 per cent on a two-party preferred basis.

Labor Party support is down four per cent at 48.5 per cent, the face-to-face poll conducted last weekend found.

According to the poll, if a federal election was held now the coalition would win government.

The Labor Party primary vote is 38 per cent (down 2.5 per cent) behind the coalition at 43 per cent (up 2.5 per cent).

Support for the Greens and independents remained unchanged.
