A new poll says most Queenslanders support the state government’s bikie gang laws, but shows support for Premier Campbell Newman has dropped.

Support for Queensland Premier Campbell Newman has slumped but most residents back the state’s controversial bikie gang laws, a poll says.

The Courier-Mail Galaxy survey shows support for Mr Newman as preferred premier has dropped from 54 per cent to 46 per cent over the past three months.

However, the Liberal National Party still leads in the primary vote with 45 per cent support compared to Labor’s 33.

The LNP leads Labor 57 per cent to 43 per cent on a two-party-preferred basis.

Of the 800 Queenslanders who took part in the poll late last week, 56 per cent said they backed the crackdown against outlaw motorcycle gangs.

About a third opposed the laws.

Queensland’s anti-bikie gang legislation, which imposes longer prison sentences on gang members and restricts their ability to meet in public, were introduced last month.
