A third attempt by Labor to move a motion of no-confidence in Health Minister Michael Ferguson has been quashed by the government again.
Opposition leader Rebecca White made the move in Parliament on Tuesday for the third time in the space of a month.
The motion was hinged on a letter to Mr Ferguson from Australian Nurses and Midwifery Federation executive director Andrew Brakey dated May 16 which was only responded to by the minister on Tuesday morning.
The letter raised the pressure felt by hospital psychiatric emergency nurses due to mounting work stresses, overtime, and long waits for a bed on a ward endured by people with mentally illness in emergency departments.
Mr Brakey said the situation for these nurses had gone "beyond crisis point", recent recruitment efforts to fill a PEN vacancy had been unsuccessful, and many of the nurses expressed "feelings akin to post traumatic stress disorder".
The letter sought a review to be undertaken on the PEN model and if new positions needed to be created to meet demand.
It sought a review on the possibility of accessing privately funded mental health beds and for an urgent meeting to be held between Mr Ferguson or a senior member of the Health department to encourage remaining nurses to stay within the state's health system.
Mr Brakey asked Mr Ferguson to confirm whether or not he would be able to attend the meeting by May 27.
Although Speaker Sue Hickey voted with the opposition parties for a no-confidence motion to be debated, the attempt failed due to government numbers.
Ms White said the motion needed to be debated as Mr Ferguson had failed to demonstrate that he understood the problems hampering the state's health system and that he failed to act on them in a timely way.
She said the government was hiding from scrutiny by not allowing the motion to be debated.
Senior government ministers dismissed the motion as a stunt.
