Multiple highway closures have occurred in New South Wales due to bushfires and a fatal crash in Queensland. In Sydney, a grass fire near Erskine Park has led to the closure of citybound lanes on the M4 highway, with motorists advised to use alternate routes. On the south coast, the Princes Highway is closed in both directions between Sublime Point and Appin Road due to a raging fire, prompting traffic diversions and warnings for travelers. Meanwhile, a fatal truck collision on the Bruce Highway in Queensland, which resulted in an explosion, has closed a section of the highway indefinitely as authorities assess damage and plan repairs. The Transport Minister has indicated that reopening efforts are underway, but significant diversions remain for affected motorists. These incidents highlight ongoing concerns about road safety and emergency preparedness in the region.
