Liberal rising star Tim Wilson is set to come under attack from the Victorian union movement, which is buoyed by internal research indicating Labor could snatch his inner Melbourne seat.

The Victorian Trades Hall Council is now set to widen its campaign to include the Goldstein electorate in addition to a slew of other Liberal-held seats.

Mr Wilson holds Goldstein by a comfortable 12.7 per cent but research commissioned by Trades Hall has Labor ahead.

Victorian Trades Hall Council secretary Luke Hilakari said voters in Goldstein did not like Scott Morrison as prime minister.
