New EY modelling shows WA taxpayers face cost blowouts on major projects if Labor abolishes the construction watchdog


Western Australians face major cost blowouts on taxpayer funded health, transport and defence projects from Labor’s plan to abolish the construction industry watchdog the Australian Building and Construction Commission (ABCC).

“A new report by EY modelled the cost impact of Labor’s plan to abolish the ABCC on Western Australian major projects and the results should send a shiver down the spine of Western Australian taxpayers,” Denita Wawn, CEO of Master Builders Australia said.

“Labor’s irresponsible policy is going to drive up costs just when Western Australian households are feeling the pinch from inflation and small builders and tradies are facing a cost and cashflow crunch,” she said.

“The EY modelling commissioned by Master Builders Australia found that taxpayers will face major cost blow outs of abolishing the construction industry watchdog,” she said.

“EY’s modelling shows that abolishing the ABCC could result in a hit of $47.5 billion to the national economy and could reach as high as $80 billion,” Denita Wawn said.

Major projects modelled by EY:

Project Estimated Cost Cost if the ABCC was abolished
Horley-Ellenbrook Railway Line Extension $1.22b 1.33b
HMAS Stirling and Henderson $280m $305.5m
Joondalup Health Campus Upgrade $257m $280.4m
