The bodies of Asra and Amaal Abdullah Alsehli are believed to have “been there for some time” when they were found in separate rooms of their Canterbury home on June 7, police said.
Their landlord had become concerned about food left in common areas of the complex and contacted police.
“The circumstances are somewhat unusual,” Detective Inspector Claudia Allcroft from Burwood Police said today.
“The girls were 23 and 24 years old and they have died together in their home, its unusual because of their age and the nature of the matter.”
Post mortems have been completed on the sisters but their cause of death is not yet known, prompting police to renew their appeal.
“Our investigation is ongoing and in consultation with the coroner we have decided to release their names,” Allcroft said.
The duo arrived in Australia from Saudi Arabia in 2017, but outside that police said they “don’t know a lot about the girls”.
“We’ve spoken to people as part of out investigation but we would like to get further information from the community,” Allcroft said.
“Any information, no matter how small you think it might be might, will help us work out the circumstances leading up to the deaths.”
Police are still waiting on the coroner’s report.
The investigation continues.
