Brad Jones remains on Liverpool's list as a back-up keeper whilst Curtis Good, Ryan Williams, Massimo Luongo and Dylan Tombides are all squad players at their respective clubs - Newcastle United, Fulham, Tottenham and West Ham United.
With both Schwarzer and Holman unsure of their club futures next season, the former Middlesbrough man felt it was an unhappy time for Aussies in England but was happy that there was some promise from fellow Australians in other European leagues.
"It's definitely sad to see, without a doubt," Schwarzer told AAP.
"I think it (England) is still one of the best leagues in the world and I think the more we have playing in the Premier League the better.
"It would be nice if these guys, especially Tommy, were able to step up and get up to a bigger league and a better league and become a mainstay in the national team."
