Upon completing his degree he reportedly worked as a paediatric registrar at the Adelaide Women's and Children's Hospital until 2013.
Kamleh then moved to north Queensland where he worked at Mackay Base Hospital, The Age reported.
He completed his final stint in the Australian medical system working in Perth until late 2014.
A university student who knew Kamleh, but did not want to be named, said he showed no signs that he would defect to the radical militant group.
"He was a pretty normal guy, he didn't have any IS related interests," she told news.com.au.
She said the "clean cut" doctor was well known in her social circle as a "womaniser" who didn't shy away from drinking alcohol.
Kamleh was also recognised by Dr Stephen Napoli, co-owner of the Mannum Medical Centre in South Australia.
He told The Age the "intelligent" doctor had interned with him for 10 weeks back in 2010.
"As a doctor he worked quite well; he was quite intelligent, he presented to our practice as quite a sound doctor with good medical knowledge," Dr Napoli said.
Dr Napoli agreed that Kamleh had shown no signs of holding extreme Islamic views.
"There was no indication I'd be worried about his other associations when he was with us.
"There was nothing that I saw of his work as a medical practical that would suggest he would have any of these sorts of views."
A former college from Adelaide Hospital also came forward reporting that he recognised Kamleh in the footage immediately.
"I was taken aback as much because I certain certainly wouldn't have associated him with an association like IS. His principle seemed to be sound and focused on the care of his patients," he told The Age.
The colleague, who also chose not to be identified, said Kamleh's behaviours were not consistent with the Islamic State's conservative views on drinking or dating.
"I know he dated a few nurses and other doctors over the years... he was heterosexual and certainly interested in the ladies, with some success."
The video featuring Kamleh, which is the latest in a string of high budget propaganda videos from the depraved militant group, shows the doctor interviewed inside the paediatric ward of a Syrian hospital.
"My name is Abu Yusuf. I made hijrah from Australia to the Islamic State to live under the khilafah," he says.
"I saw this as part of my jihad for Islam, to help the Muslim Ummah (community) in the area that I could which is the medical field."
He claims to be sad he delayed travelling to Syria for so long.
"It is disappointing to think how many fellow Muslims brothers and sisters in the medical field, who are doctors and nurses, physios, who are still living in the West and unfortunately the Muslims living here are suffering, not necessary from a lack of equipment or medicine but a mainly a lack of qualified medical care."
Yusuf urges foreign Muslims with medical training to come forward and join the latest caliphate initiative.
"We really need your help. It is not the equipment that we are lacking, it is truly just the staff. Inshallah see you soon."
Australian National University terrorism expert Dr Clarke Jones confirmed the authenticity of the video to Daily Mail Australia.
"I'm familiar with IS propaganda and this is certainly legit," he said.
The video is interesting because it's trying to communicate a sense of normalcy within the caliphate. The babies, ambulances and modern medical equipment are a far cry from the barbarity of their other videos.'
"In reality, the conditions are not accurate: Syria remains a very hostile environment. But it communicates a major shift in their recruitment."
Dr Jones believes the group are trying to attract more sophisticated demographic than in the past, when they targeted disillusioned youths.
"They are asking for foreigners with medical training and an education, and they aren't trying to lure them for militant purposes. This poses an interesting question: is this still considered radicalisation?"
The footage, which appeared on social media on Thursday, comes after nine British medical students travelled to Syria last month, claiming they were going to help treat victims of the civil war.
The students are all believed to be of Sudanese origin and were studying at a medical school in Khartoum, Sudan.
The students have been named as Lena Mamoun Abdelgadir, Nada Sami Kader, Rowan Kamal Zine El Abidine, Tasneem Suleyman Huseyin, Ismail Hamdoun, Tamer Ahmed Ebu Sebah, Mohammed Osama Badri Mohammed, Hisham Mohammed Fadlallah and Sami Ahmed Kadir.
In February, Australia's Attorney-General George Brandis announced an $18 million initiative to battle extremist propaganda.
The operation, which will be launched in July, will employ a team of technology experts to assess the impact of online extremist propaganda.
The government also plans to seek the help of platforms such as Google, Twitter and Facebook, to counter extremist messages.
