Perth's $440 million Elizabeth Quay project should be open to the public in nine weeks, the WA government insists, despite the area still resembling a construction zone.
West Australian planning Minister John Day said he expected the waterfront development - linking Perth's CBD to the Swan River - to be open by 2016, but conceded he was at the mercy of contractors.
"We're in the hands of the contractors and it is due to be completed before the end of this year," Mr Day said.
He announced on Monday that Elizabeth Quay would host concerts for the Perth International Arts Festival for four years.
Mr Day said although the Quay should be open to the public by New Year, construction at the site looked set to continue for years to come.
Oil and gas giant Chevron, the first corporate buyer of office space at Elizabeth Quay, last month requested a two-year extension to its deadline to start building its headquarters.
Mr Day said the Chevron site would remain turfed for up to three years until the work began.
The planning minister said strong private interest had been received for zones two and three, with residential, hospitality and hotel developments expected to be given the go-ahead in coming months.
