Rashid Iqbal, who qualified as a medical practitioner in Nigeria in 2001 before moving to Australia and registering as a NSW doctor in 2013, was found by the commission to have offered the 19-year-old woman $200 for sex after she rebuffed his advances in January 2018.
In a judgment released on Monday, the HCCC said that when the pair were alone on a work shift at the unnamed medical practice, the GP followed the teenager - known as person A for legal reasons - to the waiting area "and inappropriately said, 'will you have sex with me'."
"When person A replied 'No' he followed her to the back of the practice and said 'is it yes or no for sex, I will give you $200'."
At that point, person A again said "no" and left straight away "as the harassment and fear caused by Dr Iqbal was too much for her to handle".
Iqbal, who was 39 at the time, conceded offering the teen money but said it was for clothes and argued he actually said "something like 'it's not for sex' as a failed attempt at humour which he regrets".
However, the HCCC rejected the married doctor's claim, siding with the receptionist who wrote about the incident in her diary at the time, describing it as "super uncomfortable".
"We prefer the evidence of person A and find that Dr Iqbal asked person A to have sex with him, she refused and he then offered her money to have sex with him," the medical tribunal found.
"We are satisfied that Dr Iqbal used his position as the senior person at the practice to pursue a sexual relationship with person A in circumstances where he was or should have been aware he could cause significant harm."
In ruling the doctor guilty of professional misconduct and unsatisfactory professional conduct, the tribunal found that Iqbal, at other times, showed the teenager mobile phone photos of naked women, asked her out to the movies and inquired about her sexual orientation.
On another occasion, Iqbal made comments of a "sexual and unwanted nature" to person A about a patient whom he said flirted with him during a breast examination, the HCCC found.
Iqbal was also found to have repeatedly asked person A out on dates, bought her chocolates and food, and offered her lifts home "to enhance his chances of having a sexual relationship".
He later tried to cover up his "improper and unethical" conduct, according to the judgment, by telling the woman's mother, in a recorded conversation, "please don't disclose the sexual harassment", and "can I pay that $200 and just let her keep it a secret at $600?".
Iqbal's "exploitative behaviour towards a junior employee " was serious enough to justify suspension or cancellation of his registration, the HCCC found.
