The 29-year-old Shillingford took 38 wickets in five regional first class matches this season and could force his way into the final XI at Queen’s Park Oval.
Shillingford is the only change to the squad from the opening Test as selectors have placed a vote of confidence in the side which turned in a strong performance for most of that game, only to falter on the last two days.
Shillingford has not played a Test in nearly two years, despite being picked for the tour of Bangladesh last year. He underwent remedial work on his action last year after his action was deemed illegal by the International Cricket Council (ICC) and was outstanding in recent matches for the Windwards.
In his last outing, he finished with a match haul of 14 for 110. Bishoo, meanwhile, struggled in the Kensington Oval Test over the last five days, sending down 53 overs for 169 runs and taking just one wicket.
He was largely ineffective even when bowling into rough and caused the Aussie batsmen few problems.
Squad: Darren Sammy (captain), Kirk Edwards (vice-captain), Adrian Barath, Carlton Baugh, Devendra Bishoo, Kraigg Brathwaite, Darren Bravo, Shivnarine Chanderpaul, Narsingh Deonarine, Fidel Edwards, Kieran Powell, Ravi Rampaul, Kemar Roach, Shane Shillingford.
