After almost six months, the winner of a $55 million Powerball prize has come forward just days before the money was due to be sent to the revenue office.

The individual came forward to claim their prize 175 days after purchasing their unregistered ticket from Scole Lotto & News in Barkly Square in Brunswick, in Melbourne's inner-north.

Because the entry had been unregistered there had been no way of contacting the individual, leading to a long search for the winner following the draw on January 11.

The winner – who has decided to remain anonymous – took their lucky ticket to the Tatts office in Melbourne on Wednesday, seven days before the whopping $55 million prize was due to be transferred to the Victorian State Revenue Office.
