“Jamie’s development has been one of the highlights of our season so far this year and we’re pleased to have him on board for at least the next two seasons,” said South Sydney Chief Executive Shane Richardson.
“His performances on the field this season have matched his commitment to the Club and its community off the field.”
Simpson, a two-time cancer survivor, works extensivley with sick children at hospitals in Sydney as part of the club’s Souths Cares programme and also carries out other volunteer work.
“I’m really happy to be able to stay here at Souths,” Simpson said.
“I’m really enjoying playing here, and doing the work in the community with Souths Cares is very rewarding.
“I think we have a very good team here at the moment and we’re only going to get better.
“We’re all doing our best to get the Club into the finals this year and it all starts this Sunday when we play the Bulldogs.”
