British newspaper the Sunday Mirror claimed the women had engaged law firm Slater and Gordon to represent them in civil cases which, if successful, could put a significant dent in Harris' multi-million dollar fortune.

The same firm has represented 170 alleged abuse victims of British media personality Jimmy Savile, who died in 2011.

It's understood the law firm's Australian office is not involved with the Rolf Harris proceedings.

Details about the new allegations have not yet been made public and it isn't clear whether the claims are related to a file of evidence being examined by British prosecutors.

In July 2014, 85-year-old Harris was convicted and subsequently sentenced to nearly six years' jail over 12 charges of indecent assault committed in the United Kingdom between 1968 and 1986.

Last month, Harris' daughter Bindi Nicholls signed an online petition calling for a review of the conviction, claiming a "miscarriage of justice".

So far, more than 650 people have signed, though campaign spokeswoman Anne Pyke wrote it had not been presented to authorities yet because of the recent election.

As a result of the conviction, a number of organisations have stripped the veteran entertainer of honours bestowed upon him over the years.

His Orders of Australia were terminated by Governor-General Peter Cosgrove in February, while the Queen annulled Harris' CBE in March.

In his hometown of Perth, a commemorative plaque was removed from a city footpath while the Town of Bassendean withdrew the entertainer's freeman status and removed artworks from council chambers.
