A man accused of conspiring to plot a Christmas Day terror attack in Melbourne has been described as a sweet, loving sibling whose sister is shocked to see him in court.
A man accused of conspiring to plot a Christmas Day terror attack on Melbourne was the person his sister could rely on most aside from their mother, she's told a court in his defence.
Hamza Abbas, 23, is charged with conspiring to prepare a 2016 attack on Federation Square, St Paul's Cathedral and Flinders Street Station, alongside his cousin Abdullah Chaarani, 27, and Ahmed Mohamed, 25.
But his older half-sister Nabila Abbas, a maritime security guard, says the Supreme Court was the last place she ever expected him to be.
"Because of his sweet loving nature I never would have expected this from him at all," she told the court on Wednesday.
As a defence witness she was given almost free rein to talk about her brother's support for her after her divorce, his fashion sense, his stubbornness and his lack of focus in certain situations.
"After my mother, the one person I knew I could count on was Hamza," she said.
His lawyer Felicity Gerry QC sought to point out Hamza's difficulties focusing and his "fish memory".
Ms Abbas said when Hamza played video games he was "in the zone" and "a good nudge" was the only way to get his attention, but claimed that in family situations or people chatting he was usually zoned out.
She said he had also completed his VCE, had a driver's licence and that his focus had started to change after he got a painting job.
Ms Abbas was the last to give evidence in a trial, which also heard prosecution evidence from Hamza's brother Ibrahim Abbas, 24.
Ibrahim confessed to being at the forefront of a planned attack and pleaded guilty.
After seven weeks of evidence, prosecutor Nick Papas QC is expected to begin closing the crown case on Monday.
