The Western Australian state government has announced a new museum for the Perth Cultural Centre, in a project expected to be worth $428.3 million.
The new attraction – which will also house a scientific research institution – will sit among the state's flagship cultural icons on Francis Street.
According to culture and the arts minister John Day, the development comes as the state government strives to transform Perth into a vibrant and modern capital city.
"Our current museum has served the state well for 120 years, however this new museum will provide contemporary spaces and better public access with state-of-the art facilities and strong links to the regions," he said.
"A well designed and operated museum adds enormously to the civic, cultural and educational life of a city and state which the WA Museum will be able to do so much more effectively following the redevelopment."
Mr Day explained that significant preparation had already been carried out to ensure the sustainable development of the site, including a new strategic and business plan, financial modelling and master planning.
Forward work is expected to begin in 2015 following the release and awarding of tenders, while construction will commence the following year.
The state museum is set to be completed in 2019-20.
