The North West region has spent almost $11.9 million on locum health staff in the 2018 - 19 financial year, budget estimates have revealed.
Health Minister Michael Ferguson said fly-in medical staff have cost the state a total of $25.2 million in the last financial year to the end of March.
Medical locums are specialists or other staff who are temporarily engaged to fill gaps in health services due to illness, holiday leave or other shortages, such as a lack of specialist skills.
The North spent almost $8.2 million on locum stuff and the South spent $4.9 million.
Mr Ferguson said, based on projection figures, the Tasmanian Health Service were expecting to spent $1 million to $2 million less in the 2018-2019 financial year than the previous year.
