Iranian-born Man Haron Monis took more than a dozen customers and staff hostage at the upmarket Lindt cafe in the city's financial heart on December 15, an incident which shocked the nation.
An inquest into his death and the deaths of two hostages at the end of the 16-hour siege, is probing Monis' motivations -- including whether he was a "lone wolf" prosecuting an IS-inspired terrorist act or a deranged individual.
Monis was referred to a psychiatrist in May 2010 after he ended up in hospital complaining of dizziness.
"He was very evasive in his answers -- he felt that he was being watched all the time, even in his bathroom," psychiatrist Kristen Barrett, who first saw Monis that May, told the court.
"My impression was that he had chronic schizophrenia and my treatment plan was to start anti-psychotic medication."
Barrett said she had prescribed medication for Monis and he seemed to improve, but by early 2011 he stopped taking the drugs and a few months later ended their sessions.
Customer Katrina Dawson, a 38-year-old barrister and mother-of-three, died from a ricocheting bullet fragment in the incident which Prime Minister Tony Abbott described as a "brush with terrorism".
In his opening address on Monday, counsel assisting the coroner Jeremy Gormly said Monis' mental health issues would not provide the full answer to what caused his actions.
By 2014, Monis' life was unravelling -- financial and legal problems were mounting and he had few friends and no standing with any group or institution, including Australia's Islamic community which did not accept him, it has heard.
