The Australian actor, who is best known for his role in crime drama Underbelly: A Tale of Two Cities, has moved out of Sydney's Northwest Private Clinic after more than 200 days of psychiatric treatment.
Newton initially entered the centre last year after allegedly attacking former girlfriend Rachael Taylor during a trip to Rome. He briefly checked out earlier this year before breaking his apprehended violence order by trying to get in touch with Taylor and then entered the clinic again.
His lawyer Chris Murphy told The Daily Telegraph: "I can tell you he is now out of the clinic and I'm sure he's doing fine. He is now a daycare outpatient who is still receiving treatment but I can tell you he is fine."
Various agents and talent managers in Australia have said that getting Newton's career back on track could prove difficult for him.
One said: "There's still a lot of compassion for Matt despite what has happened. He has already directed and written indie feature films, and that's probably his best option. There may be forgiveness at some stage, but not soon."
Newton had all charges dropped against him in a court appearance over his broken AVO after Murphy claimed that he is suffering from a significant mental illness.
