South Australian teammate Chadd Sayers has labelled Cricket Australia's decision not to offer Travis Head a national contract a "disgrace".
Head, the former vice-captain of the Test side, failed to make the cut in Cricket Australia's 17-man contract list for 2021-22 announced on Friday.

CA handed out 20 men's contracts a year ago, but trimmed that number for the coming year that features a Twenty20 World Cup in India and a home Ashes series.
Head, Will Pucovski, Joe Burns, Mitch Marsh and Matthew Wade were all dumped from the list, while Steve Smith, David Warner and Marnus Labuschagne were the only specialist Test batsmen included.
Sayers tweeted it was an "absolute disgrace" to overlook his state skipper Head, who was set to tour South Africa before posting scores of 223 and 142 for South Australia during a productive end to the Sheffield Shield season.
Trevor Hohns, Cricket Australia's chairman of selectors, indicated that Head and other snubbed players remain in the mix for the five-Test series against England, adding they will be upgraded to a central contract if they play enough international fixtures.
"There's no secret that there's positions available," he told reporters.
"It's a concern there's no stand out (opening partner for Warner).
"We're challenging our players to really put their hand up again at the start of next season."
Concerns over lack of white ball cricket before Ashes
All-rounder Cameron Green is in the box seat to remain at No.6 in the first Test, but it is clear that at least two batting spots will be up for grabs later this year.
Pucovski loomed as the leading contender to open alongside Warner against England, but Hohns cautioned the prodigy is in the early stages of recovery from shoulder surgery.
"With no real guarantee that he'll be fit for the start of the season," Hohns said.
"It's looking promising and we all hope he is.
"What we'd like to see from Will is he gets fully fit, back on the field and scores some runs. If he's doing that then I have no doubt he'll feature quite prominently in our discussions."
While England are playing a stack of red-ball cricket in coming months, Australia won't don the baggy green until they return from the T20 World Cup for the home summer.
"Very concerned about that, there can be no doubts," Hohns said.
"Hopefully there will be plenty of Shield cricket programmed leading up to the first Test match. I believe there will be.
"But that is not going to help some of our players because hopefully they're going to be fully engaged in the T20 World Cup. It's a difficult one."
Cricket Australia contract list for 2021-22: Ashton Agar, Alex Carey, Pat Cummins, Aaron Finch, Cameron Green, Josh Hazlewood, Marnus Labuschagne, Nathan Lyon, Glenn Maxwell, Tim Paine, James Pattinson, Jhye Richardson, Kane Richardson, Steve Smith, Mitchell Starc, David Warner, Adam Zampa.
