The condition of one Bondi Beach terror attack victim has deteriorated but two more survivors of the devastating Sydney massacre have now been discharged from hospital.

Of the nine Bondi Beach victims who remain in hospital, three are currently in critical but stable conditions.

That includes one patient at St Vincent’s Hospital whose condition deteriorated on Friday night, from stable to now being critical but stable, according to the latest NSW Health update.

The last Bondi patient being treated at Royal North Shore Hospital was discharged on Saturday, and one of two patients still being treated at St George Hospital was also discharged on Monday.

It comes just over two weeks after the deadly December 14 mass shooting.

A total of 40 people were injured, and 15 innocent people were killed, in the massacre targeting Jewish Australians celebrating Hanukkah.

The survivors were sent to various hospitals across Sydney as the public rallied to support them, with a record-breaking number of blood donations to boost reserves left dwindling after the carnage.

At the time of the mass appeal for donations, there were still 38 victims in hospital.

“NSW Health extends its deepest sympathies to the families, friends and loved ones of those who died and were injured at Bondi Beach,” NSW Health said on Monday as it updated patient conditions.

One patient is in a stable condition at Prince of Wales Hospital.

One patient is in a critical but stable condition at St George Hospital.

Two patients are in a critical but stable condition and two patients are in a stable condition at St Vincent’s Hospital.

Three patients are in a stable condition at Royal Prince Alfred Hospital.

One of the patients, injured police officer Scott Dyson, 25, underwent surgery almost daily before he was woken from an induced coma on Tuesday.

He suffered multiple gunshot wounds while responding to the mass killing, allegedly carried out by father and son Sajid and Naveed Akram.

A brave bystander, Ahmed Al Ahmed, also remains in hospital after springing into action.

The Sydney tobacco shop owner, who had migrated from Syria, was out for coffee when he heard the gunshots ring out and risked his life to wrestle a weapon free from one of the alleged terrorists.

He was later shot five times in the attack and has been through multiple surgeries in hospital.

As his condition improves, it is expected that Ahmed will soon be discharged.
