Historic preservation exists in Sydney and is overseen by the New South Wales State Heritage Register, established in 1999. Some of Sydney's grandest edifices have been replaced with contemporary architecture, a trend which began in the 1960s and has continued throughout to the present day. Lax heritage conservation in Sydney has attracted the ire of Sydneysiders, who are often in opposition to what government or local authorities want for the city, something seen recently with government contesting the heritage-status of the Sirius building at The Rocks. The demolition of the Regent Theatre on George Street in 1988, which had been slowly falling into disrepair, is a reflection of the shoddy heritage attitudes that persisted in the 20th-century, despite protests from Sydneysiders and pleas for green bans: the ornate Free Classical-style theatre was purchased cheaply by property developer Leon Fink, who subsequently demolished the building days after purchasing it. Sydney Mayor Clover Moore, then the MP for Bligh, addressed a crowd in Martin Place in 1988 to help save the building.
