A Brisbane councillor could face thousands of dollars in fines, and even be referred for suspension, after a local real estate agent complained he was being "harassed and stalked".

The city's only Greens councillor, Jonathan Sri, has been referred by Brisbane City Council's CEO to the Councillor Conduct Review Panel for investigation, according to a letter obtained by the ABC.

The complaint will also be considered by the Ethical Standards Unit, which could result in a referral to the state's corruption watchdog for misconduct.

In May, Cr Sri posted to social media, making allegations against Michael Mangelakis, a real estate agent in Brisbane.

In the post Cr Sri said he had called and emailed Mr Mangelakis seeking a meeting to discuss tenancy complaints.

Mr Mangelakis wrote to Brisbane City Council in February and then on three occasions in June, complaining that Cr Sri had breached the councillor's code of conduct.

In a letter written by council CEO Colin Jensen to Cr Sri, he outlined Mr Mangelakis' emails.

"Mr Mangelakis emailed council … alleging harassment and stalking by you, taking the form of attempts by you to involve yourself in tenancy disputes between REMAX Highgate Hill and certain tenants," Mr Jensen wrote.

"Mr Mangelakis attaches an [undated] email from you [in your capacity as councillor for the Gabba Ward] to him, which complains that he is refusing to return calls.

"The email from you refers to conversations had between you and a number of former tenants and expresses concern about different aspects of Mr Mangelakis' conduct as a real estate agent."

Mr Jensen then informed Cr Sri he had been referred to the review panel and that he "may have engaged in misconduct or inappropriate conduct".

"Mr Mangelakis has provided a copy of an email from you to him, which could be argued to show that you have engaged with former tenants of properties managed by REMAX Highgate Hill and have then sought to intervene in matters appropriately addressed between landlord and tenant," he wrote.

'The whole system of rental laws in Queensland is flawed'

In response to the allegation of interference, Councillor Sri said he intended to continue "naming and shaming" agents who in his opinion were "engaging in questionable practices with regard to tenants".

"I think more political representatives should be naming and shaming dodgy real estate agents," Cr Sri said.

"The whole system of rental laws in Queensland is flawed, and creates fertile ground for exploitation and bullying of tenants.

"When landlords and agents have the power to end people's tenancy for no reason, or jack up the rent drastically, this gives them a huge amount of power over renters' lives.

"We need new rules that protect tenants' right to remain in their home and which require landlords to justify steep and unreasonable rent increases.

"The first stage of the State Government's review of tenancy laws closes in less than a month, and I know lots of tenants are raising concerns."

A Brisbane City Council spokesman said council did not make comment on individual Councillor Conduct Review Panel (CCRP) matters. Mr Mangelakis declined to comment.

If Councillor Sri is found to have engaged in misconduct or inappropriate conduct, the review panel can order him to make an apology, make a recommendation to the minister for the councillor to be suspended or for the CCC to investigate his conduct, and can fine him up to $6,500.
