Asked by counsel assisting the coroner, Jason Downing, why he was picked to be the primary negotiator, he responded: "I think that at the time Reg just said 'go primary'."
The officer identified as "Reg" was the team leader and negotiation co-ordinator during the siege, and was effectively second in the chain of command on the negotiation team.
The primary negotiator was the third person in the chain. "I don't think I've had any formal courses since 2009," he told the inquest, adding however, that he had been involved in more than 100 negotiations since 2004, "whether it's Father's Day, Christmas, full moons".
Asked by Downing whether he had been involved in any hostage events, he replied: "Personally, no I haven't".
"I've been in role playing ... having hostages ... but I haven't done any real situations where there were hostages".
He was also asked about the use of a dictaphone for recording conversations with hostages, telling the inquest that he never before used one. But he decided to take on the responsibility on the day of the siege, as the negotiation team initially worked from a 4WD and then from a cramped gaming manager's office at a nearby leagues club.
The recordings of phone calls to and from hostages up until 1.16pm on the day of the siege, which included those made from the 4WD, have not been recovered. Peter said he could not remember what the dictaphone looked like or what type it was. "I'll let you know, I'm not real good with technology," he said.
The inquest continues.
