Woodman Point will become a major focus for recreational sailors, with four new public boat ramps and boat stacking capacity for more than 300 vessels.
Planning and Infrastructure minister Alannah MacTiernan said the government expected to release tenders for building the boat ramps and would invite expressions of interest in constructing and operating a boat stacking facility during February.
Ms MacTiernan said the Woodman Point Recreational Boating Precinct would help meet rapidly growing demand for storage and launching facilities on the metropolitan coast.
"As well as eight boat ramp lanes, a service jetty and the boat stacker, the harbour will offer more than 350 car/trailer bays and additional public car parking.
"Future plans being considered for the precinct include the development of boating related retail space and industrial areas, and possibly the addition of boat pens.
"With the south-west metropolitan population growing rapidly, demand for these facilities can only get stronger.
"Construction of the new boat ramps and car parks could begin as soon as the middle of the year.
"Timing for the boat stacker and associated facilities will depend on the timetable of the successful tender, but obviously we will be favouring proposals that deliver early completion."
The minister said the planned expansion would not intrude upon facilities leased and operated by the Cockburn Powerboat Club and an existing boat storage operation.
