I think the cost of infrastructure in Australia is a joke. Was just reading that refurbishing the Queensland gaba stadium for the Olympics would cost something like 3 billion. A billion is a thousand million. How can it cost 3 billion to refurbish (not build!) a stadium? Are they putting in solid gold seats?
I read on the ABC it's because when we outsource work to the private sector, we also outsource the planning. So the private sector gets to decided timelines and the cost of everything as well
