Don't think so, NSW Government and Gladys can overrule Clover Moore using SafeWork NSW see below. There could be criminal charges levied against Sydney City Council and the NSW Government should the fireworks go ahead according to SafeWork's website.
If Gladys tries to pass the buck to Clover Moore, an avowed leftie to the left of even the Socialist Left's Albanese and McKay, the NSW Socialist Left supported candidate against Minns, it will make Gladys Berejiklian look even worse. www.safework.nsw.gov.au/fireworks-display But I think Clover Moore should probably cancel it to avoid a stoush with Gladys that undoubtedly Gladys would win.
