The planned explosive demolition of an old Victorian power station turned out to be a bit of a bust.
Aluminium giant Alcoa had planned to completely demolish its Anglesea power station in a controlled explosion - but only part of the structure collapsed.
"The safety of all site personnel and the community is Alcoa's priority," Alcoa site asset manager Warren Sharp said in a statement.
"We are currently working with the principal contractor to assess the site and plan for the remainder of the structure to be demolished."
The company does not know if the remainder of the demolition will be done by explosives.
The power station is on private property and not accessible to the public, with a 110-metre exclusion zone being enforced by security officers.
Preparations for the demolition have been underway for some time and the mostly steel structure will be recycled.
The station and mine closed 2015 before being subject to a 12-month asbestos removal program.
