Organisers of Sydney's Sculpture by the Sea event claim a new footpath being built within the exhibition area could lead to the art festival's downfall.

David Handley, founding director of the event, has threatened to pull the event from Bondi due to a planned 279m concrete footpath, aiming at improving disability access around Marks Park. 

Mr Handley says that the path would take out eight of the 10 prime spots that give the event its 'wow' factor and would lead to the festival's 'very slow and painful death'.
