A court was told that Brisbane psychiatrists believed Joel Cauchi was “fit and appropriate” to possess a gun license in 2021 after finding that schizophrenia men had “little risk” to others.

Cauchi, 40, Jade Young, 38, Jade Young, 47, Yixuan Cheng, 27, Pikria Darchia, 55, Dawn Singleton, Faraz Tahir, 25 and 30, and injured 10 people on Westfield Bondi Junction on April 13 last year before he was shot dead by police inspector Amy Scott.

He provided medical certificate to Cauchi in January 2021, known only as Dr. C, "so that he can visit the range of guns and practice target shootings", he told the NSW coroner court on Thursday.

Dr. C told the investigation, and then a Queensland Police official contacted him and asked Dr. C to provide "firm advice" for Cauchi's "Declaration of Qualification" application and if he thought he was "a fit person, a weapon permit could be issued."

Dr. C wrote to police, telling them that Cage “poses an imminent risk to himself or others at this stage” and that his schizophrenia is eased.

The court was informed that police guidelines state that a person must have a gun permit “little risk” to public safety.

"Considering my assessment, … I think he was the one who posed a very low risk to himself and others at that time," the psychiatrist said.

Cage has no history of aggressiveness or violence, he said, adding that it is very difficult to assess future risks.

Dr. C only met Cauchi once. He contacted Cauchi's former long-term psychiatrist (DR A Dr) to ask for his new patient's medical records, but only a limited history was obtained.

He admitted in court that when Cauchi was inconsistent with his medical history, he missed a "red flag".

The investigation found that Kuch told him that he had been taking antipsychotic drugs (clozapine) for two years.

When Dr. C visited Cauchi's medical notes, he learned that he had taken the drug for severe schizophrenia for 15 years.

Despite the red flag, he offered advice on gun permits - for the first time in his career he advised the police.

Cauchi left his hometown of Toowoomba less than a year ago.

The court heard his mother was worried that her son believed she was under Satan's control and Cage's extreme obsessive-compulsive disorder, obsessive-use of pornography and gait changes.

Dr. C was not informed of Cauchi's mother's concerns in A's paperwork, but was able to verify that Cauchi had been supervised to have detached antipsychotics from antipsychotics.

The court was informed that the certificate of qualification was limited to certain circumstances - only available under supervision at the Pistol Club.

"I'd do a lot of different things in hindsight," Dr. C said, adding that he could have been more persistent in Cauchi on a second date and diligent in getting treatment before giving the certificate.

He also said he should contact Dr. A directly to learn more about his history.

Earlier Thursday, a GP who had been treating Cauchi for 15 years said he would be “very worried that his schizophrenia patients might have a decline in their mental health if he was told about the concerns raised by his mother.

Dr. Richard Grundy told the investigation that he last saw Cauchi in Toowoomba in August 2019, when he was "quite stable".

Grundy said Thursday that if he was later told that Couch's mother had concerns about her behavior after she was removed from the antipsychotic, he would be "very worried" that Cage's schizophrenia symptoms might recur.

Cauchi left Toowoomba in March 2020, the court heard. In a discharge letter to Grundy, then psychiatrist Dr. A wrote that Cauchi moved to Brisbane and was no longer eligible for A.

Asked by senior legal counsel assisting coroner Peggy Dwyer SC, Grundy said he had no reason to suspect Cauchi needed psychosis because the letter did not include details about the mother's concern or that he had been weaned the antipsychotics.

"I thought Joel was fine," Grundy told the court from London via video link.

He said he had “no information” about Cauchi’s mother’s private practice during seven concerns between October 2019 and February 2020.

"I would have tried to contact him," he said, and he also wanted to discuss the behavior with Cauchi's therapeutic psychiatrist.

The court was informed that A's letter was vaguely worded, especially in a sentence - urging GP to "remember" Cauchi - could be read in two ways.

Therefore, the GP did not take action and believed that Cauchi did not need his care.

Cauchi has been managing his appointments and is a punctual and compliant patient, Grundy said.

"Joel has always been a person appointed by himself and if he had any concerns about any health problems... he would have contacted the GP for evaluation and if referrals were required, they would have made a referral."

"He can go back to practice anytime, anywhere. I never recall or chase someone who lives in another city and ask them to come back to see me."

He also said a call claimed she had asked the GP about the ongoing care of Kuch "nothing happened".

Dr. A told the court Tuesday that she felt "completely relieved" after she discussed Cauchi with Grundy and possibly recalled the patient.

But Grundy said Thursday there was no such call.

"If the expert asked me for a phone call, I would open the patient's documents and write down their concerns and not record the call," he said.

A person who claimed to have repeatedly called on Grundy about Cauchi's health. Grundy denied being A.
