Former Network Ten presenter Jesse Baird, 26, and his Qantas flight attendant boyfriend Luke Davies, 29, disappeared from Sydney's east on Monday.
Neither has been heard from since.
What do we know about their disappearance?
Their disappearance is being treated as suspicious after blood-stained possessions belonging to both men were found in a skip bin in Cronulla about 11am on Wednesday.
Two hours later, Baird's terrace home at Brown Street in Paddington — nearly 30km away from the Cronulla site — was declared a crime scene after police officers found blood inside the property.
Davies was not at his home in nearby Waterloo, although police believe he was in Paddington on Monday.
His family has been unable to contact him and he hasn't been at work, police said on Thursday.

"Witnesses talked about some shouting on Monday earlier in the morning," she told reporters on Thursday afternoon.
"But it wasn't reported to police at the time ... it was only reported to police (on Wednesday)."
Early investigations indicated there was a struggle, with furniture moved around in the home, Radmore said.
Blood found at the property also indicated someone had suffered a significant injury.

Police found a phone, credit cards, a wallet, and a set of keys inside the skip.
Two cars have also been seized from the Paddington property, along with a third from another location.
On Friday, police said a 29-year-old man was in custody as part of investigations into the disappearance.
What don't we know about their disappearance?
While the possessions found in the Cronulla skip were bloodied, and the blood inside Baird's Paddington home indicated a serious injury, police could not yet say if one or both of the men had been harmed.
It is not known what either man was wearing at the time of their disappearances.
Radmore said one of the men was still using social media on Tuesday evening, but wouldn't confirm who.
Police have asked anyone with any information to come forward.
