Docomomo Au have started a petition to oppose the demolition of this highly significant modernist building. 

Please consider supporting the petition to help save the MLC. 

Below from their description of the building:

The MLC Building (by Bates Smart McCutcheon, 1954-57) is proposed for demolition.  The MLC Building, 105-153 Miller Street, North Sydney, is the most significant large office building dating from the 1950s in Australia. It is an important component in the development of North Sydney, makes a significant contribution to the streetscape and played a seminal role in the development of the Modern high-rise office building in Australia.

The MLC Building, North Sydney, is one of the most important mid century modernist buildings in Australia.
