An expansive park built above Rozelle’s multibillion-dollar spaghetti junction interchange has been closed after asbestos was found in garden mulch around a children’s playground – with the contractor involved confirming the mulch was also used elsewhere in Sydney.

An urgent audit was under way to determine what other sites could be affected by what the premier, Chris Minns, described as “a toxic substance”.
