Millions of fish have washed up dead in southeastern Australia in a die-off that authorities and scientists say is caused by depleted oxygen levels in the river after recent floods and hot weather.

Residents of the Outback town of Menindee in New South Wales state complained of a terrible smell from the dead fish.

Sydney authorities on Thursday deployed baited lines to try to catch a giant great white shark that devoured an ocean swimmer, as beach communities in Australia's largest city were rocked by the first such attack in decades.
