Brisbane’s air quality is set to worsen again today, as a public health warning remains in place across South-East Queensland.

Bureau of Meteorology forecaster Victoria Dodds warns that conditions will deteriorate today as a cold front moves across the state, bringing more smoke

Queensland chief health officer Dr Jeanette Young said that the effect of the smoke was cumulative, and that people who are at risk, including young children, the elderly, and those with respiratory conditions, should seek to remain indoors.

Indigenous groups have protested for two days outside of the Alice Springs police station to demand an investigation into the shooting of 19-year-old Kumanjayi Walker at his family home on Saturday.

Aboriginal organisations in the Northern Territory are calling for an “immediate and exhaustive” investigation into the police shooting death of  Mr Walker, a Warlpiri man.

International firefighters have been flown in from New Zealand to assist with fighting bushfires in Queensland.

Interstate crews from Tasmania and the Northern Territory will also assist as the blazes worsen today and tomorrow, with more than 50 fires still burning across the state.

QFES Acting Commissioner Mike Wassing said, “We've got a couple of tough days and then we're into another week of weather that really doesn't see any rainfall, and potential further erratic conditions again into the weekend.”

Irukandji jellyfish are a dangerous part of Australia’s beaches, but scientists at James Cook and Griffith University are working to create better detection methods.

Professor Kylie Pitt said “Jellyfish leave behind DNA in the water as they swim through it and we can actually reliably detect whether or not jellyfish have been there by just taking a water sample and scanning it for the presence of Irukandji DNA.”

Currently, surf lifesavers sweep beaches with nets in high-risk areas to detect the jellyfish, but this is unreliable.

As part of the goal, the airline will invest $50 million over 10 years to build a sustainable aviation fuel industry that will limit its net emissions from 2020 and double the number of flights offsetting carbon emissions.

Alan Joyce, chief executive of Qantas Group, said the 2050 target was “ambitious but achievable”.

An American submarine that was missing in the Second World War was rediscovered at the bottom of the East China Sea.

In 1944, the aircraft carrier "Grayback" and its 80 crew members were missing when they were attacked by Japanese aircraft.

After searching for military documents with the correct coordinates, an underwater exploration project found the submarine near the Okinawa coast in Japan.

The original coordinates were incorrectly translated and the numbers were missing.

The small country of the West African Gambia has filed a lawsuit in the United Nations Supreme Court, formally accusing Myanmar of genocide against Rohingya Muslims.

It is initiated by the International Court of Justice, which usually decides on disputes between States.

Last year, the United Nations issued a condemnation report on the violence in Myanmar, saying that military leaders should be tried for genocide.

The Myanmar government denied that its troops had committed such crimes.
