Murphy is one of 28 players included in the squad which also features three Cricket Australia contracted players - Aaron Finch, Glenn Maxwell and James Pattinson.
"It's obviously nice to get to where I've been aiming to for the past four years," Murphy said.
"But it's only the beginning of my journey and I know that I still have a lot of hard work ahead of me."
The spin bowler who plays Victorian Premier Cricket for St Kilda is joined by Brody Couch (Geelong), Tom Jackson (Geelong) and Cameron McClure (Essendon) as first-time rookies in the squad.
Last season, Murphy made his debut for the Victorian second XI after strong form at club level.
