If you look at the content of the report, it all sounds marvellous, but I lost concentration when this grabbed me, even though I think an tunnel might be a great thing. I do like an nice tunnel.
The Museum also wants to extend an tunnel — dug in 2000 when the car
park was built — underneath the Exhibition Building to connect with a
lift, which would whisk visitors up to the first floor - where there
would be a permanent exhibition on democracy in Australia - and then
upwards to the roof.
