Two people were killed and four others injured in two separate traffic accidents in Queensland, northern Australia, on Wednesday, authorities said.

A head-on collision near Breddan, over 1,000 km northwest of Brisbane, left a woman in her 50s dead at the scene. The driver, a man in his 50s, was hospitalized with non-life-threatening injuries. The other vehicle’s driver, a woman in her 40s, was critically injured.

Earlier, a three-vehicle crash near Bajool, about 500 km away, claimed the life of a 24-year-old SUV driver. Two pickup drivers were hospitalized.

The incidents come during Australia’s National Road Safety Week, as officials urge motorists to slow down amid rising road deaths.
