Wildfires that threatened Australia's capital, Canberra, over the weekend have been brought under control as containment lines held and hot and windy conditions eased, prompting authorities to lift a state of emergency. While fire in the ACT, home to the capital city, has spread to more than 55,000-hectares (136,000-acres), close to a quarter of the territory's entire landmass, the heat-fuelling the danger is subsiding.
