Queensland Premier Campbell Newman is being urged to sideline his health minister as doctors at public hospitals threaten to resign en masse over individual contracts.

Mr Newman returns to Queensland this weekend after a 10-day trade mission to the US.

Public hospital senior medical officers are set to be placed on individual contracts.

But with senior medical officers continuing to resist plans for individual contracts, Opposition Leader Annastacia Palaszczuk says the premier needs to intervene.

"The premier today needs to sideline his health minister and take action, take control of the health crisis and fix it," she told reporters in Brisbane.
