Roberton has signed a two year extension, keeper him at the club until at least the end of 2017, while Shenton has signed a one year deal, making him a Saint until 2016.
Roberton, 23, has played 37 games for St. Kilda since moving across from Fremantle at the end of 2012 due to a lack of game time.
Shenton, 24, has played 23 senior games with the Saints, after enjoying a breakout year this season, playing all but two of St. Kilda’s 10 games.
Coach Alan Richardson said he is very pleased to secure the pair’s signatures and it is a strong show of faith that the club is headed in the right direction.
“Dylan and Cameron have continued the positive momentum around our players committing to the club’s future – they are confident that we are heading in the right direction and want to be part of that,” he said.
“This follows on from Jack Steven committing to a five-year deal at the start of the year and our Saints Future Fest campaign last year under which saw 19 of our young players put pen to paper.”
