James Packer's $1.5 billion casino, hotel and apartment complex at Barangaroo risks becoming a "symbol of inequality" looming large in Sydney's centre, the City of Sydney says.

The council has used its response to the plans lodged by Crown Resorts to highlight its ongoing concerns with the proposed changes to the precinct, including the "insufficient planning evidence" to justify building the "landmark" tower on an area previously earmarked for parkland.

"The proposed relocation of the intended waterfront parkland to Hickson Road at the the foot of very tall residential towers places more importance on the casino and its customers being waterfront than the public on parkland being waterfront, as the current planning controls require," the council said.

This relocated park would have limited view access, suffer from wind downdraughts "and will feel hemmed in by private development," it added.
