❓ Mr. Zempilas questions the Premier about the cost estimates for Perth Park, citing Infrastructure WA's concerns. The Premier defends the project, highlighting its economic benefits and contrasting it with past projects by the opposition.

Perth Park—Business case81.Mr Basil Zempilasto the Premier:I refer to Infrastructure WA's summary assessment report for Perth Park, which states:… the business case and supplementary information did not provide sufficient detail to ascertain the veracity of these cost estimates.(1) Why should the public believe the Premier's claim that the project will cost only $217.5 million?(2) Does he promise that this project will be delivered for $217.5 million?

Mr Roger Cook replied:(1)–(2) I thank the member for the question. The release of Infrastructure WA's assessment is an important milestone for delivering on this exciting project, which was an election commitment to the people of Western Australia. Their feedback has been incorporated into the project team's ongoing work as the design is finalised before we move into major construction. The business case was completed independently and in accordance with the requirements of Treasury and Infrastructure WA and the strategic assessment management framework. As required, the business case was reviewed by Infrastructure WA, and we released a summary of the business case, as promised. It returned a 1.84 benefit–cost ratio undiscounted analysis and, as a result, WA will generate $61 million in economic activity each year because of this project.We make no apologies for going through the correct process to make sure that this project has a business case and can be managed properly. This stands in sharp contrast to those on the other side when they were in government, whether it was on the Forrestfield–Airport Link or the Perth Freight Link. They did not even do a business case for Optus Stadium—an important piece of economic infrastructure. We will continue to make sure that we do what we need to do to drive value for money for WA taxpayers, and we will continue to do what we need to do to make sure that we keep our election commitments.
