Opposition leader Mark McGowan launched a campaign in the Mirrabooka electorate, claiming constituents were �hoodwinked, misled and lied to� by the Barnett State Government.
The State Government project envisioned a 22-km system that would extend from Mirrabooka through to the Perth CBD, with stops along Dianella Road, Alexander Drive and at Edith Cowan University Mt Lawley campus.
Mr Nalder said the public was already aware of the delay in the light rail project.
He said in 2013, former Treasurer and Transport Minister Troy Buswell announced a three-year delay in the project in response to the financial climate.
Mr Nalder said he used this delay to ask the Department of Transport to consider interim or alternate proposals to ensure best use of the available funds, including a light rail or bus option.
Mr McGowan said Perth�s congestion would be worse than Sydney�s.
�It is extraordinary and disturbing that Perth is going to be the congestion capital of Australia within a few decades,� he said.
�We are launching a campaign around the electorates of the northern suburbs to make sure everyone here understands that Mr Barnett and the Liberal Party got people�s votes on a false pretence.�
According to the MAX Light Rail project website, the State Government is committed to delivering the project in full.
