Hedge fund millionaire Angus Murray is working on a plan to redevelop Sydney’s South Head national park, including a wheelchair accessible path, elevated walkway and short term accommodation.

Mr Murray said his $80 million vision for the national park, which would be serviced by a private ferry operated between Circular Quay and Watsons Bay, was his way of making amends for his hunting trips to Africa.

"Years ago I did go shooting in Africa, I can’t say I’m proud of what I did and I think we all make mistakes," Mr Murray told the Herald. "This is definitely me probably doing what I always wanted to do, which is be involved in nature and genuinely making some kind of difference."

The former Macquarie Banker, who currently resides in London, said the proposal would make the national park wheelchair accessible.
