Nude bathing enthusiasts have slapped down a plan to build an elevated walkway through the clothing-optional Lady Bay beach near South Head, saying it will expose them like animals in a zoo.

The $80 million proposal, which would include a three-kilometre wheelchair accessible path through the national park, has been met with strong opposition by locals and nudists.

London-based financier Angus Murray plans to transport tourists to the small headland via a private, ticketed ferry from Circular Quay. The plan would also refurbish the park’s eight heritage buildings and restore the war tunnels at Signal Hill Battery.

The hedge fund millionaire says he feels compelled to repay the environment after shooting African game earlier in his life.
