Neglected sculpture

I am very concerned at the state of Jan Torcrea's 'Father and Son' out at North Head Port Jackson, Australia. This late work of Torcrea's is overgrown and in serious need of cleaning and restoring. It is admittedly fenced off, so unlikely to be damaged - I gather this was done after an attempt to steal it in 1998 -, but the plaque giving the details and title of the work has long since vanished and should be replaced. It is sad that one of the few works of this most distinguished of lesser-known Australian sculptors (an early student of Henry Moore) exhibited outside his native town of Cooladdi has been allowed to get into such a state.
