I live on the gold coast and i can tell you nothing has started. Nothing is council approved. To my knowledge, the land hasnt even been purchased yet.
The whole thing is an idea, and not yet reality. We all wish that something would happen sooner, but land is expensive, buildings cost many many hundreds of thousands of dollars, and council to date has not yet approved anything. I wish Allan the very best with this project, but it still could be many many years away.
A museum in the heartland of Pinball, being Melbourne would also be a great idea oneday.
