???Lord of the Rings??? star Cate Blanchett has put her luxury apartment in Sydney, Australia up for sale for ?L6.7million. The flat in the historic Astor building is currently listed as ???Price Upon Request??? but there???s apparently a guide price of 12 million Australian dollars. The huge apartment is the largest apartment in the building and was originally three separate apartments in 1923. ???Dame Edna Everage??? funnyman Barry Humphries reportedly illegally turned two apartments into one flat when he lived there 35 years ago. The building???s board had no idea of the dramatic ??simprovement??? until Humphries invited them all to a party at which he greeted them as he descended the new circular staircase. The last owner bought another three-bedroom apartment in 2006 and combined that to create an even bigger apartment with five bedrooms, four bathrooms, separate living areas and study with panoramic views over the Domain to the Opera House. Cate and her husband Andrew Upton have sold most of their Australian real estate and bought an English manor in East Sussex in 2015. There???s no hiding the apartment???s celebrity ownership as it is being mark?Zeted as Cate???s home. And on one table, there???s a host of awards including an Oscar and a BAFTA.
