An Australian firefighter has been killed while battling bushfires north of Sydney, as dozens of blazes continue to burn across two states in what authorities warn is the start of a dangerous summer fire season.
The 59-year-old volunteer died on Sunday night after a tree fell on him while he was working on a fireground near Bulahdelah, around 200km north of Sydney. Emergency crews said he went into cardiac arrest and died at the scene.
