Rip up the contracts? Why public-private infrastructure deals need to change

Written by Graeme Hodge, Monash University / Published by The Conversation.

Victoria's public-private partnerships (PPPs) are a mess. Their democratic standing has never been lower. They have always trumpeted better value for money and more timely delivery, but with the contract for the estimated $17.8 billion East West Link about to be "ripped up" it now looks more like a circus.

Few winners will emerge from the coming fight. Though incoming Labor Premier Daniel Andrews should be applauded for planning to release the East West contract, the deadline for doing so has long past.

The East-West Link is dead – a victory for 21st-century thinking

Written by Peter Newman, Curtin University / Published by The Conversation.

Labor's state election victory in Victoria has fatally undermined Melbourne's most controversial tunnel, the now-doomed East-West Link, with new Premier Daniel Andrews pledging to rip up the contracts for the project.

His decision is a victory for anyone who values 21st-century urban thinking over the outdated car-first mentality.

Complacency rules as Queensland makes risky edict on sea-level rise

Written by Justine Bell, The University of Queensland / Published by The Conversation.

Queensland Deputy Premier Jeff Seeney's decision, revealed this week, to order a Brisbane council to remove future sea-level rise from its planning regulations seems a rather short-sighted thing to do.

His directive, issued to Moreton Bay Regional Council in the city's north, flies in the face of the overwhelming scientific consensus that average global sea levels will rise by 2100.

Dave Troy: Social maps that reveal a city's intersections - and separations

"Every city has its neighborhoods, cliques and clubs, the hidden lines that join and divide people in the same town. What can we learn about cities by looking at what people share online? Starting with his own home town of Baltimore, Dave Troy has been visualizing what the tweets of city dwellers reveal about who lives there, who they talk to — and who they don't."

This talk was presented at an official TED conference and filmed in October 2014. It is available from the TED website at <>.
