In 2005 the West Australian Football Commission released a $235 million plan (excluding transport infrastructure or land acquisitions) to increase the stadium to a 60,000 seat venue in a staged project.
However, this proposal became a matter of significant debate in Western Australia.
Although the demand for a larger stadium was undeniable (in 2005 the West Coast Eagles had 42,000 season ticket holders in a 43,500 seat stadium), the option of developing and expanding Subiaco in order to meet this higher demand was called into question.
An alternative plan was tabled for the construction of a new stadium which would seat 70,000 and have retractable seating to cater for rectangular field codes, and appeared to be the lead candidate.
Others argued that it may be more cost effective to re-develop Subiaco to 60,000 seats, and redevelop Perth Oval, a small rectangular stadium in Perth, to 35,000 seats to cater for rectangular field sports.

The Government of Western Australia had already commenced development of a major stadia review project in late 2003 which led to much interest in the future of major sporting venues in Western Australia.
A major stadia taskforce was appointed in early 2005 and released the Perth major stadium interim report in June 2006.
The taskforce delivered its final report in May 2007, which recommended the construction of a new 60,000 seat stadium at either Kitchener Park (which adjoins Subiaco Oval) or in East Perth, suitable for Australian rules football, cricket and also rectangular-field sports such as rugby.
It recommended against the further development of Subiaco Oval, which would be demolished.

In July 2007 the Government of Western Australia announced its preference to build a new 60,000-seat stadium rather than re-develop Subiaco Oval.
Early the following year, the Government confirmed that Subiaco Oval would be demolished for the new Perth super-stadium to be built at the adjacent Kitchener Park.
The new 60,000 seat stadium would be built between 2011 and 2016, with the majority of the stadium being completed in 2014.
Subiaco Oval was set to be demolished between 2014–2016 to allow the end of construction on the new stadium.

Following the election of a new state Liberal party government, Premier Colin Barnett, announced in February 2009 that, in light of the state's deteriorating finances, his government had scrapped plans for a new outdoor stadium.
He stated that a new stadium, including an alternative proposal to redevelop Subiaco Oval, would not be considered for at least two years.
However, in December 2009 he announced that he wanted to demolish Subiaco Oval and build a new stadium so Perth can host soccer World Cup games in 2018 or 2022.
He stated that this would involve a complete demolition of the old stadium and the building of an entirely new stadium on the site, and suggested this would likely cost well in excess of $450 million.
