Chevron weighs anchor at Perth's Elizabeth Quay site THE Australian branch of US oil giant Chevron is planning one of Perth's largest skyscrapers at the Elizabeth Quay development, with market pundits predicting it could develop a tower worth up to $1 billion. The company has been in talks with the city's Metropolitan Redevelopment Authority for months to buy a site and its purchase of a 6795sq m lot for $64 million last Friday will have far-reaching ramifications for the city's office market.
