A tragic attack at Bondi Junction's Westfield shopping centre has ended with six people dead and eight people still in hospital, after a 40-year-old Queensland man went on a stabbing rampage on Saturday afternoon. 

While details of the incident are still emerging and NSW police continue their investigation, in a statement to Queensland Police the family of the man said he has "battled mental health issues since he was a teenager". So how do we address gaps in Australia's mental heath system?
