News.com.au writes about this, citing a statement from the National Capital Authority (NCA), which deals with planning and land management.
The material says that in December 2008, the NCA issued a lease permit to Russia, in 2011 the right to work and build was obtained.
According to the lease agreement, Russia undertook to build the building within three years, but the project was never completed.
The head of the department, Sally Barnes, noted that the work in progress violates the overall aesthetics, importance and dignity of the territory reserved for diplomatic missions.
“Although initial work has already begun, this block has been standing as a construction site with construction in progress for many years,” she said.
Barnes added that the NCA has been discussing this issue with the Russian side "for many years."
As soon as the place is cleared, it will again be offered for diplomatic purposes.
