Police have found a mobile phone on the banks of a dam that could provide a major breakthrough in the search for missing mother Samantha Murphy.
The 51-year-old was last seen leaving her Eureka Street home to go for a run in the Canadian State Forest on the morning of February 4.
Police resumed the search for her remains on Wednesday and found a mobile phone near a dam south of Buninyong.
Video captured by the ABC shows police celebrating as they made the discovery on the banks of the dam.
Police charged 22-year-old trader Patrick Orren Stephenson in March with the murder of Ms Murphy in Mount Clear on the day she went missing.
He will return to court in August.
Stephenson is the son of Orren Stephenson, who played 15 AFL games for Geelong and Richmond between 2012 and 2014.
Since February, police have launched several searches in the bushland as part of the investigation.
More to come.
