The State Opposition is forecasting that staff shortages at Fiona Stanley Hospital will cause in further cost blow-outs.

It is still uncertain that how many full-time comparable staff is required to service the $2 billion hospital. However, a 2012 internal report suggested the place will be short of 115 staff members during the early six-month roll-out.

As per an internal report obtained by The Sunday Times, there is a ‘high risk’ that Fiona Stanley Hospital will face widespread staff shortages across a number of specialties. This will include burns, obstetrics and nearly all areas of nursing.

The State Government has said that it is making strategies to fix the gaps by rostering staff members across different sites, during that period.

Labor's Health Spokesman Roger Cook says that it is an indication that the government has failed to prepare its staff.

According to him, “The Department of Treasury and Finance have identified a number of financial and operation risks in relation to Fiona Stanley Hospital”.

It is estimated that the new $2 billion hospital, which reached practical completion this month, will need 3208 full-time health staff when it is fully up and running. These consist of 727 medical appointments, 646 medical support staff and 1835 nurses and midwives.

Doctor Weize declares that the process of employment has already started. The hospital is being constructed in Murdoch in Perth's south and is due to open in 2015.
