Greg Lynn trial: Russell Hill given ultimatum to tell wife of Carol Clay affair years before their deaths, court told

Russell Hill told his family he was no longer seeing Carol Clay after being given an ultimatum in 2006 by a neighbour to tell his wife about the affair he was having, a murder trial has heard.

Robyn Hill told the Victorian supreme court on Tuesday that her husband told her he was camping alone when he left their Drouin home about 7.30am on the morning of 19 March 2020.

He said he would be camping in the Wonnangatta Valley, a place the couple had previously camped in together and which he knew well and enjoyed visiting. She helped her husband pack, and gave him $20-$30 cash for lunch so he did not have to use his credit card, the court heard.

Hill tuned in to high frequency radio almost every night at 6pm to speak with other radio enthusiasts and friends, but Robyn Hill said he told her he would not do so that night as he would be unable to set up his antenna in time once he arrived.

She heard his voice on the radio the next night. She told police he was missing on 25 March, after he failed to tune in to any other radio meetings.

Robyn Hill told the court that a neighbour had given Hill an ultimatum in 2006 to come forward to his wife about an affair with Clay, otherwise the neighbour would. After the ultimatum, Robyn Hill believed her husband had stopped seeing Clay.

Hill had also previously told Robyn Hill that Clay was his first cousin, but she said that she later discovered that was not the case.
