An Australian Islamic State militant involved in a plot to behead a person in Sydney sobbed on the phone to a fellow recruiter as he described the moment he watched his commander die in battle.

A private phone call between IS fighter Mohammad Ali Baryalei, from western Sydney, and Hamdi Al Qudsi were played during the alleged recruiter's trial in Parramatta District Court on Monday.

Baryalei, who defected to Syria in 2013, said he was desperate to return to Australia and explained to Al Qudsi that he was 'over' watching his comrades die in battle, the Daily Telegraph reported.

'At first I started crying I was just ... that day I don't know. We got smashed man,' Baryalei said.

Phone calls and text messages intercepted by counter terrorism officers will be presented as evidence in the trial against Al Qudsi who allegedly worked with Baryalei to help seven IS recruits travel to Syria between June and October 2013, the ABC reported.

Baryalei was heard telling Al Qudsi he would connect the alleged recruiter with his leaders and that he wanted to 'open the door' for other recruits to join militant groups like the Al-Nusra front, Islamic State or Al Qaeda groups, according to the Daily Telegraph.

The court heard Al Qudsi phoned his colleague to report that more 'brothers' would be arriving in Syria imminently on June 25, 2013, while a day later he discussed four 'soccer players' going on a trip with Wassim Fayad.

WHO IS MOHAMMAD ALI BARYALEI? Mohammad Ali Baryalei was believed to have recruited up to 30 Australians fighting in the Middle East. He was named as a co-conspirator in 2013 a terrorism plot to film a person being beheaded in Martin Place around seven weeks before reports of his death emerged. Baryalei attended two Catholic schools in Sydney's west before he worked as a nightclub bouncer in Kings Cross. He was said to have suffered abuse at the hands of his father as a boy and left home at the age of 17, earning money by doing 'odd jobs' for neighbours who needed help. Friends said battled with mental illness and suffered extensive bouts of depression which saw him confined to his room for days on end. He was also said to have a love of gambling, women and drugs such as cocaine. Baryalei travelled to Syria in April 2013 and there were reports he had been martyred at the end of October, 2014, however the Australian government have not been able to confirm his death.

'There are four brothers and there are more coming, after that and I have told them you are the emir when they arrive — this is now starting to be very serious,' he told Baryalei who is believed to have been killed during a coalition air strike in 2014.

Al Qudsi's lawyer has argued the prosecution will have to prove his client organised the men to travel to Syria with the understanding they would be fighting with the militant groups, the ABC reported.

'Just because someone goes to Syria it doesn't mean they're going there to fight,' Scott Corish told the court.

'Could there be another reason to go and somehow help these people ... who are in need of humanitarian aid and in harm's way?'
