Australia news as it happened: Three ISIS brides arrested after arriving in Sydney, Melbourne; US strikes Iran near Strait of Hormuz

NSW Health is advising residents in Sydney’s Sutherland Shire to stay alert for signs and symptoms of measles after it received notification of a confirmed case.

The person was a returning traveller from South-East Asia, where measles outbreaks are surging.

They visited several locations in the Sutherland Shire, including health facilities, while infectious. The full list of those locations is available on the NSW Health website.

Measles risk is at its highest level in NSW since 2019. Since January this year, there have been 47 recorded cases.

Physician Dr Anthea Katelaris said people should monitor for symptoms, particularly if they had visited one of the listed exposure locations in recent days.

“Symptoms to watch out for include fever, sore eyes, runny nose and a cough, usually followed three or four days later by a red, blotchy rash that spreads from the head and face to the rest of the body,” she said.

The United Arab Emirates said it had responded to a missile and drone attack on Friday, hours after the US said it thwarted attacks on three navy ships in the Strait of Hormuz and retaliated against Iranian military facilities.

Iran and the US are trading blows as their negotiators are seeking a deal to end the fighting. So far, they have avoided a return to all-out fighting.

The UAE said its air defences were engaging missile and drone threats from Iran early on Friday.

There were no immediate reports of damage in the UAE.

The UAE’s defence ministry advised residents not to approach, photograph or touch “any debris or fragments that have fallen as a result of successful air interceptions”.

Indonesian authorities are rushing to rescue 20 hikers after the eruption of a volcano on Halmahera island on Friday.

Mount Dukono, in North Maluku province, erupted on Friday at 7.41am (10.41am AEST), spewing volcanic ash as high as 10 kilometres into the sky, the country’s volcanology agency said.

The agency maintained the alert status at the mountain at its third-highest level.

Iwan Ramdani, the head of the local rescue agency, told Reuters it had deployed dozens of personnel, including police, to search for the 20 hikers trapped by the eruption.

Nine of the hikers were Singaporean and the rest were Indonesians, Iwan said.

Numerous Sydney private schools have been caught up in a worldwide ransomware attack on the Canvas learning management system, which has also prevented university students from submitting assignments.

The criminals behind the hack say they have obtained sensitive student information and are demanding institutions pay a ransom by the end of the day on May 12.

The operators of Canvas say the hackers — who are calling themselves ShinyHunters — may be in possession of identifying information, including names, email addresses, and student ID numbers, as well as messages between teachers, students, and parents.

At UTS, the entire system was taken down as a precautionary measure, leaving students unable to submit assignments. All students have been granted an automatic extension until Monday.

The University of Sydney said the platform was working correctly yesterday, but a message this morning said a global outage occurred about 6am.

A list of institutions that fell victim to the hack has been published online by the hackers but has not yet been verified.

The NSW Department of Education said 54 public schools were hit, though a spokesman estimated the risk of a breach of sensitive information to be “low”.

Other institutions, including The King’s School in Sydney, have also been impacted. The school believed the stolen data was limited to students’ names and assignments. A letter to parents yesterday said a “criminal threat actor” had access to parts of the Canvas system between April 25 and 29, according to an internal investigation.

“Instructure [Canvas’ owner company] has taken steps to secure its systems and has engaged law enforcement agencies, including the FBI,” the letter stated. “There is no indication that passwords, dates of birth, government identifiers or financial information were accessed.”

Barker College has also informed parents that external specialists have been called in to manage the fallout.

Reddam House wrote to parents stating there was no indication that passwords, dates of birth, government identifiers, or financial information were disclosed.
