Where do you put a 20-tonne bird standing seven storeys high?

Bunjil, the 25-metre eagle sculpture that has towered over Docklands for a decade, needs a new home.

A $1.5 billion development is to push it out of its existing spot in the median strip on Wurundjeri Way.

The developer Lend Lease has the green light for a development on a 2.5-hectare plot at Batman's Hill, off Collins Street. The plans include 100,000 square metres of office space and 600 apartments in seven towers, with a public plaza in the middle. It also means Bunjil needs to be moved - no easy task. The cement slab supporting the structure is thought to weigh 90 tonnes.
