Murphy is available for manager Alex McLeish after a difficult 18 months plagued by injury.
He told bcfc.com: "Spending two weeks on tour together does help the players to bond. We had a great team spirit last season. I wasn't part of the team because I was injured so it's good to be back amongst it now and playing games.
"It's the best squad in terms of team spirit that I've been involved in and that will stand us in great stead for the new season."
