Sipping a cocktail while looking over Sydney Harbour will be elevated to a new level of enjoyment if plans to redevelop the redundant ''hammerhead crane'' at Garden Island get the go-ahead.

With the various ''high'' experiences available in the city, from the Bridge Climb to the Sydney Tower walk, the chance to hold a wedding, corporate function or just enjoy a drink 60 metres above the hurly burly is gaining momentum.

Private developer Luxcon Property Group has lodged a plan with the Department of Defence for an ''adaptive re-use'' of ''the hammerhead crane''. The proposal is to create Sydney's newest landmark, a unique entertainment venue and historic tourist attraction.

Heading Luxcon is Ilya Melnikoff, a nephew of Harry Triguboff who has a passion to preserve what he sees as iconic assets.
