St Kilda Pier will be rebuilt if the Andrews government is re-elected, under a plan released by local Labor MP Martin Foley.

Mr Foley, who holds the marginal seat of Albert Park by just 3 per cent, said Labor would spend $50 million to build the new curved pier in the popular tourist destination.

It will include a new penguin viewing area, tiered seating providing access for swimmers to the water, new toilets and sheltered areas.

He said the new design would also deliver better public open space, preserve the kiosk, and ensure the pier remained a focus-point for visitors.
