House prices across Australia are expected to continue falling over the coming months, according to analysis by property data firm Cotality.

More than 90 per cent of capital city suburbs across the country have recorded a declining property market over the past three months.

Sydney saw the biggest drop in August, falling 1.4 percent, followed by Melbourne and Canberra.

Cotality says the possibility of another rate hike, negative real wage growth, and persistently low levels of new housing supply mean the downward trend is not expected to let up any time soon.

Around 900 of these workers are believed to be trapped since the torrent of water, mud and debris tore through the border area of Nepal and Tibet.

Authorities in Nepal are warning of possible fresh flooding, urging residents in flood-affected districts to remain on high alert. Flood warning notices have been sent to people's phones, as rescue crews work to clear a major highway connecting Kathmandu to one of the areas worst hit by last week's catastrophic floods. At least 800 people have been confirmed dead, but thousands of others are still missing in Nepal and Tibet including 43 Australians. 

Attorney General Michelle Rowland says the government wants to bolster Australians' safety through a series of new privacy protections. Under the proposal, companies could no longer justify collecting more information than they need. People will also be given the right to erase their data from platforms and there'll be stronger rules on how organisations respond to data breaches. 

And administrators of the embattled Bathla Group say its demise is just days away if they can't secure urgent funding to pay 350 staff by Thursday. The major property developer went into administration last week with debts exceeding $3.2 billion.
