Mascot Towers building 'sinking'

Displaced residents of Sydney's troubled Mascot Towers are concerned by the latest engineers' report, which identifies "a new issue" with the cracking building that suggests it may be sinking.

The report, provided to the owners' corporation yesterday afternoon, said it appeared the building was "moving in a downward motion" and urged owners and tenants to remove all their possessions.

Fabiano Dos Santos, who only bought into the building three months ago, said he feared the worst.

"It's very, very concerning, and they [are] asking the owners and tenants to start to remove everything from the units there, so we didn't expect that at all. The first interpretation is that the building is sinking."

ACL donates $100k to Israel Folau

Israel Folau has received a $100,000 donation from the Australian Christian Lobby (ACL) after GoFundMe's decision to cancel his crowdfunding campaign.

The ACL said it hoped to amplify the voices of "quiet Australians" by helping Folau.

"There is an outpouring of support for Israel Folau from the Australian community, who see Israel's case as their case," ACL managing director Martyn Iles said.

Meanwhile, the furore over Israel Folau's $3 million GoFundMe appeal could spark a review of how crowdfunding sites are monitored, experts say.

Workers exposed to radiation

Production has stopped at a newly opened nuclear medicine facility at Sydney's Lucas Heights and a full investigation is underway, after two workers were exposed to a radiation dose above the statutory limit.

The Australian Nuclear Science and Technology Organisation (ANSTO) said three workers were "attended to by radiation protection personnel" after contamination was detected on the outside of a container holding Molybdenum-99 (Mo-99) on Friday morning.

"Early calculations indicate that the radiation dose received by two of the workers involved in medicine processing was equivalent to that of a conventional radiation therapy treatment," a spokesperson said.

The spokesperson said supplies of Mo-99 were being provided by alternative facilities at ANSTO while the investigation was underway.

City of Sydney declares climate 'emergency'

City of Sydney councillors have voted to declare that climate change poses a serious risk to residents and should be treated as a national emergency.

In a Lord Mayor Minute, Clover Moore asked the council to call on the Federal Government reintroduce a price on carbon to meet the Paris Agreement emissions reduction targets, and to ensure Australians employed in fossil fuel industries found appropriate alternative employment.

"Successive federal governments have shamefully presided over a climate disaster, and now we are at a critical juncture — we face a climate emergency," the Lord Mayor said.
