tayser2,
I was following the progress on the station from the local Melbourne newspapers.
From what I read it was suppose to be opened two years ago, and as you mentioned the delay was caused by the fact the station remained opened during construction.
Also, I've read the Premier is under fire recently about the value of P3 partnerships including this project.
All that aside, I believe it's a fantastic project for Melbourne, something to be truly proud of. I'm glad your government officials resisted calls for building "a normal roof" for far less money, and instead invested in a beautiful piece of urban infrastructure.
