4 May 2011 – Planning expert John Mant and veteran of the 1970s Green Bans Jack Mundey will take part in a debate on urban development after showing of a documentary, State of Siege, about the conflict between development and urban conservation by Sydney resident, Dennis Grosvenor at Macquarie University this Friday, 6 May.

The film’s publicity describes how Mr Grosvenor, on return from holidays, found his once verdant Ku Ring Gai neighbourhood, scattered with bulldozers; workers demolishing heritage buildings, ripping up fertile soils and gardens and chopping down remnants of the age-old surrounding bushland.

Previously declining developer requests to purchase his property, he had no control over this destruction in his neighbourhood: the NSW government had enacted laws accelerating the approval process for large urban developments, stripping the rights of local councils, and resident consultation.

Marco Amati of the Graduate School of the Environment will also take part in the debate after the film which will show at 5.10pm to 7pm at Building Y3A, Theatre 1 on the university campus.
