Romilly Madew, of the Green Buildings Council of Australia, welcomes the government's Smart Cities Plan, but calls for greater emphasis on sustainability.
"While other industries continue to debate the business case for sustainability, the property and construction industry in Australia has shown real leadership," said Madew.
"The Sydney Opera House has laid down the gauntlet for the property industry with a pragmatic, practical approach which shows even the most iconic, historic and challenging buildings can be high-performing, energy efficient and sustainable."
