Support for the Liberal government has increased slightly while votes for Labor are falling off towards independents, the latest opinion polling shows.
The November EMRS state voting intentions report showed that support for Labor dropped from 32 per cent to 29 per cent, while the Liberal government increased its support by one percentage point, to 39 per cent.
Support for independents jumped by three percentage points, to 19 per cent, according to the survey.
EMRS managing director Paul Jamrozik said the results showed a shift in voter support away from Labor towards independents.
"While support for the Liberal party has remained stable, what's notable is the switch in support from Labor," he said.
"We've been watching the level of support for an independent candidate increase over time, and this poll reflects their strongest position yet."
Independents now have the support of nearly a fifth of voters, making them a bigger political force than the Greens, who polled at 12 per cent, down from 14 per cent in the previous survey.
The result reverses 12 months of steady gains for Labor, whose support increased in each of the past three EMRS polls.
After briefly overtaking Premier Jeremy Rockliff as preferred Premier in the May EMRS poll, Rebecca White's support slipped to 39 per cent in August, and to 35 per cent in the latest result.
Premier Rockliff maintained his lead as preferred Premier, with 42 per cent support.
"The surge in voter support for an independent or other minor party, at the expense of Labor, is reflected in the decline in personal support for Labor Party leader, Rebecca White," Mr Jamrozik said.
He also noted that nearly a quarter of voters remained undecided - the highest proportion since March 2017.
The survey of 1000 registered voters was taken between November 20 and 27.
