The exact details of the Macgregor scam have not been publicly released and it is not known how much the property was sold for.
Attorney-General Simon Corbell said the government was very concerned "a scam of this magnitude may have affected residents in the ACT".
He said the government did not anticipate publicly releasing information at present as the facts were not yet fully clear and the matter may be the subject of an investigation.
Mr Corbell revealed documentation confirming the suspected fraudulent property sale was handed to the Office of Regulatory Services on July 11.
He said the office was reviewing the circumstances of the sale.
