The troubled Melbourne Star observation wheel at Docklands is expected to reopen within weeks.

The tourist attraction had to be rebuilt after developing cracks soon after opening in late in 2008.

The operator has announced it is on track to recommence operations by the end of December but says final work is “weather dependent.”

However, construction is now complete and the final commissioning process is under way.

Spokesman Chris Kelly says they are working to the earliest possible opening date, possibly late this month.

“We are now well into the commissioning process, which is the final stage before opening but some activities do remain weather-dependent,” he said.

“The message at the moment is watch this space.”

The wheel is 120 metres high which is the equivalent of a 40-storey building.

The 30-minute ride offers 360 degree views, including the CBD, Port Phillip Bay, Mount Macedon and the Dandenong Ranges.
