A widespread effort to save wombats with deadly mange disease at a national park in Tasmania's north has been unsuccessful, according to researchers from the University of Tasmania. 

A sarcoptic mange outbreak began in the park in 2010, depleting the population by more than 90 per cent. 

Five months into the treatment regime in 2015, nearly all of the wombats showed no signs of mange, but the treatment wasn’t successful long term and the disease has now reduced the National Park's wombats to as few as three.

New Liberal Senator for New South Wales, Andrew Bragg has used his maiden speech to back an Indigenous voice to parliament in the constitution.

He spoke out against some of his colleagues who have labelled the voice a "third chamber", and explained it would not have the standing, scope or power of the Senate or the House of Representatives.

Senator Bragg said almost every comparable nation has landed some form of legal recognition of First Peoples and Australia should not wait any longer.

The US senate has passed legislation guaranteeing permanent benefits for 9/11 victims.

The vote for the legislation came after intense lobbying from first responders, many of whom are suffering from illnesses and injuries related to exposure to toxic chemicals.

The Pharmaceutical Society of Australia (PSA) has released research showing an "alarming" number of medication-related errors as part of a push for a change in Australian laws that would require pharmacists to report mistakes they've made when dispensing medicine.

Brisbane City Council, objects to ratepayers paying $3.2 million, to buy six hectares of state-owned land to protect threatened koalas in Brisbane's south.

The council argues the Queensland government should itself keep the remnant bushland near Toohey State Forest near Nathan as koala habitat, or gift it to the council.

But the state government argued the council wrote to State Development Minister Cameron Dick on February 26 and offered to buy the land at a concessional price.

A Queensland coal mine owned by the BHP Mitsubishi Alliance has been fined $200,000 for dumping dirty water into a nearby river.

After admitting to causing environmental harm in court, a BMA spokesperson said they acknowledge what occurred was unacceptable and are focused on continuous improvement.
