Rocks and sand dredged from Port Phillip Bay during channel deepening works should be used to create an archipelago of man-made islands for visitors and wildlife, some tourism operators say.
One operator has even suggested calling the new destination Brumby Island, in honour of Victorian Premier John Brumby.
Sorrento sailing operator Kerry Murphy, a member of the Eco Island Taskforce, says his group's long-standing push for the islands has been renewed with the Port of Melbourne Corporation (PoMC) preparing to start dredging in the bay next month.
The archipelago could be created from non-toxic material to be dredged up, dumped on existing spoil sites, Mr Murphy told AAP.
It would be located equal distance from Werribee, Sandringham and Melbourne's Docklands, he said.
"On a day like today, it would be packed," he said.
Mr Murphy said the plan was more environmentally friendly than dumping millions of tonnes of rock and sand on the seabed and would create new land the size of Melbourne's CBD.
Ill fish discovered in Port Phillip Bay

The health of Melbourne's Port Phillip Bay is under scrutiny just weeks before dredging is due to start, with the discovery of sickly fish, a Fairfax newspaper reports.
The Environment Protection Authority is investigating evidence that at least seven species of fish are ill or carry lesions, The Age newspaper said.
Laboratory test are being carried out on flathead, blowfish and cobbler following anecdotal reports of lesions on four other species, trevally, whiting, ludrick and bream.
The fish all come from the north-west part of Port Phillip Bay between Port Melbourne and Werribee South.
Reports indicate the problem might have started in December.
Health authorities have warned people not to eat or touch the fish.
"As a precautionary measure, people should avoid touching or eating any fish that have lesions, or are lethargic and looking generally unwell," a Department of Human Services spokesman told the newspaper.
The news has prompted renewed calls to reconsider the controversial bay dredging project, which could release new toxins and contaminants into the bay.
Scientists question Yarra toxic sediment

Testing of the possible effects of dredging toxic silt from the mouth of the Yarra River as part of the controversial $1 billion channel deepening project is inadequate, scientists say.
While the CSIRO was approved the project, senior scientists have told The Age newspaper the Port of Melbourne Corporation had not answered key questions about what might happen when the silt, which contains 150 years of heavy metal and pesticide pollution, is dredged and dumped in the middle of Port Phillip Bay.
Former CSIRO environmental projects office chief Dr Graha Harris said the port's last report on the project's environmental impact was not a true ecological risk assessment that may not give a full indication of contamination levels.
"My best judgement is that this document tends to downplay key risks associated with human and environmental impacts and assumes more rapid recovery of the bay after the project than may be the case," he said.
lets hope they don't start trying to ram this ship and throw acid on it:
Protesters greet Dutch dredging ship
http://news.smh.com.au/protesters-greet-dutch-dredging-ship/20080129-1onr.html
The giant dredging ship, the Queen of The Netherlands, has been greeted by protesters waving red flags and a flotilla including kayakers on its arrival in Melbourne's Port Phillip Bay.
The channel deeping project to begin on Friday will involve the removal of 23 million cubic metres of sand, rock and toxic sediment from the bay to enable larger, super container ships to dock.
The Blue Wedges Coalition, which will make last ditch application in the Federal Court on Tuesday to have the project overturned, said the red flags signalled distress.
"There are some kayakers intending to enter the Yarra (in protest), but without breaking any marine regulations."
Mr Lawler said Dive Victoria had three chartered boats and there were several smaller, private boats that joined the flotilla as part of the protest.
The PoMC and the Victorian government claim the project will bring $2 billion in economic spin-offs.
Meanwhile, Victorian Premier John Brumby has been forced to defend a decision not to release contract details of the dredging of Port Phillip Bay after the contract price was given to the European stock exchange.
The Victorian government and the Port of Melbourne Corporation had refused to say how much the Dutch dredging company, Royal Boksalis Westminster, would be paid for its work, citing commercial-in-confidence restrictions.
But Fairfax newspapers reported on Tuesday that the figure of $500 million already had been provided to the Euronext stock exchange in Europe.
A spokesman for Boksalis, Roel Berends, told Fairfax from Amsterdam the PoMC had agreed the contract's value could be made public in Europe.
