Two senior officials at Egypt's National Council of Women confirmed that Ms Sharobeem, who has lived in Australia for 30 years, was at their offices in the upmarket suburb of Nasr City in Cairo about two months ago, requesting a letter that states she had worked for the government body, in order to renew her national identification card.

The revelation comes just a day before ICAC is due to begin public hearings into allegations Ms Sharobeem, the former CEO of two publicly funded community health organisations, misused credit cards, submitted false invoices, spent money on personal items and used public money to renovate a property she owned.

With Ms Sharobeem due to give evidence over two days in the second week of hearings, it is unclear if she remains in Egypt or has returned to Australia. Her lawyer Mark Smith did not respond to a request for comment.

On Friday, the ICAC revealed it had called Ms Sharobeem's entire family to give evidence - her sons, Richard and Charlie, as well as her husband, Haiman Hammo. Ms Sharobeem ran the Immigrant Women's Health Services organisation for 11 years until 2015 and the Non-English Speaking Housing group. It's understood Richard Sharobeem had a role with the housing group and concerns were raised about the purchase of a car.

Fairfax Media can reveal that the Egyptian NCW rejected Ms Sharobeem's request for confirmation of previous work, with sources telling Fairfax Media "she was never employed with us and was a trainee for about three months. We had no formal ties with her whatsoever".

The comments are a fresh blow to Ms Sharobeem's unravelling life story, contradicting her claims to have worked for the NCW as an external relations manager, an organisation that was headed by Susan Mubarak, wife of then Egyptian president Hosni Mubarak.

In February, Fairfax Media revealed that the powerful NSW Crime Commission had sought and won an asset freeze in the NSW Supreme Court covering four Sydney properties, her car and her bank accounts.

In Egypt, the two NCW officials reiterated that the job listed on the national ID card should have never listed her affiliation with the council.

"She came here around two months ago saying 'I need an official letter from the council stating that I worked here back in 2002', we told her 'no' straight away," the most senior official told Fairfax Media.

"If she really thinks she's that clever in fooling people to believe she worked for us then she should show us the written evidence."

When presented with media records from 2002 in the state newspaper Al Ahram and the Kuwaiti News Agency that listed her position as external relations manager for the council, both were visibly upset at how Ms Sharobeem had misled journalists.

"She had no relation with us in an official capacity," another senior official reiterated. "She was just a trainee and I am astounded that she managed to mislead so many people with such ease."

A third official in the National Council of Women recalled that Sharobeem was a good networker in the formative years of the council.

"We were only about 20 in the office. She was a trainee who was good at networking with various members, going from one person to the next of the newly formed council because there weren't so many of us, but she was far from the manager of external relations that she claimed to be. She was never employed."

Amongst witnesses due to give evidence in the first week of the ICAC hearings are committee members of the IWHS who worked with Ms Sharobeem as well as the auditor who qualified the organisation's 2015 accounts, revealing Ms Sharobeem owed at least $100,000 in wrongly claimed reimbursements for that year alone.

Ms Sharobeem rose to prominence on the back of an inspiring life story in which she says she was forced to marry her first cousin as a teenager, escaping a violent marriage, before he died. She emigrated from Egypt and says she earned two PhDs, one in psychology and another in business administration. Those claims are now the subject of ICAC inquiries.

Fairfax Media has previously reported that Ms Sharobeem is not registered with the national health practitioner regulator, despite having publicly claimed to be a psychologist.

She earned numerous appointments to federal and state government boards, including the Multicultural NSW Advisory Board, the Australian of the Year advisory council and the Settlement Services Advisory Council. She has since resigned from them all.

Ms Sharobeem was hired last year by broadcaster SBS as its community engagement manager. She resigned, citing ill health, around the time of the asset freeze.

In a judgment freezing her assets, Justice David Davies noted the maximum penalty for the alleged fraud was five years in jail.
