The Australian Islamic State recruiter Neil Prakash, also known as Abu Khaled Al Cambodi, features in a highly-produced video urging his "brothers in Islam" to launch attacks in Australia.
"You must start attacking before they attack you," he said in the recently surfaced video. "Send a message to my brothers, my beloved brothers in Islam in Australia... when are you going to rise up and attack them for attacking you?"
The video came just days after three Australian teenagers were charged over an alleged Anzac Day terror plot thought to be inspired by Islamic State.
Monash University Terrorism expert Greg Barton said there was a link.
"It was almost certainly released this week because of events on Saturday. It is possible they were holding over initially the video until after, they were hoping for a successful operation," he said.
However, both the Victoria's Acting Chief Commissioner Tim Cartwright and Victoria's Islamic Council secretary Kuranda Seyit said they were not aware of any link between the charged men and Prakash.
"It was almost certainly released this week because of events on Saturday. It is possible they were holding over initially the video until after, they were hoping for a successful operation."
Neil Prakash said in the video that Muslims needed to stand up for their sisters, in the wake of rising Islamophobic sentiments in Australia.
"All I hear in Australia is this sister was hurt. This sister's hijab was ripped off."
He referred to his "dear brother Numan", likely a reference to Numan Haider, the 18-year-old shot dead after stabbing officers outside Melbourne police station in September 2014.
"The media has portrayed that we come here, that we’re social outcasts, that we had nobody, that we have to turn to Islam because we were just troublemakers in the past," he continued in the video. "But this is far from the reality.
"We came to establish a state, we came to give our blood, we came to pave the way towards establishing the caliphate (Islamic State)."
Prakash, who is Fijian-Indian and Cambodian, converted to Islam before travelling to Syria in early 2013.
