The survey comes as the body representing Queensland's senior medical officers prepares to challenge the contracts in the state's industrial relations commission.
Of the 780 senior medical officers surveyed by the Australian Medical Association (AMA) of Queensland, 84 per cent said they would resign, move interstate or reduce their hours if the contracts were introduced.
"Losing so many senior doctors would cripple our hospitals," AMA Queensland President Dr Christian Rowan said.
Retaining medical professionals and the reduction of patient research was also a concern for 90 per cent.
Legislation introduced to parliament in October will enable doctors earning over $130,000 to be put on individual contracts.
Health Minister Lawrence Springborg says something has to be done control overtime, with one doctor clocking up $600,000 in extra pay.
But doctors aren't backing down, with the Australian Salaried Medical Officers' Federation of Queensland (ASMOFQ) lodging a dispute on their behalf with the Queensland Industrial Relations Commission.
"This Government has an 11th hour opportunity to right an enormous wrong," ASMOFQ president Dr Nick Buckmaster said.
