NSP Chairman Andrew Hilditch has strongly defended the selections saying it was time Australia was back on top of the world rankings and this team reflects Australia's best chances in Sri Lanka.
"It is obviously a very important time for Australian cricket as we strive to get back to the top of world rankings in Test cricket, but at the same time is a very exciting opportunity for this squad as it takes on Sri Lanka on its home soil.
"We believe the squad has a really good blend of experience and young talented players who we are sure are ready for the challenges ahead," said Mr Hilditch.
It's clear Australia's loss in the 2010 Ashes Series against England has impacted the team, coaching staff and the selection panel.
"Since the immense disappointment of the Ashes series, the coaching staff and playing group have worked tirelessly to prepare for the challenge ahead.
"There is a quiet confidence about the group and we are sure this squad will do all in its power to get the Australian Test team back to where it needs to be in world cricket."
Two of the surprise selections came in the pace department with James Pattinson and Trent Copeland entering the team for the first time.
"Trent has earned his position with some fine performances for New South Wales and has bowled very well on the Australia A tour.
"James is a young fast bowler with the potential to play an important role for Australia in all three forms of the game and we look forward to watching hisâ€¨further development during this tour.
