Socceroos coach Ange Postecoglou has stuck true to his word that he's prepared to look beyond the tried and tested in the final two second round World Cup qualification matches, with some unexpected names in contention for a spot.

Centre-back Milos Degenek, left-back Alex Gersbach and forward Apostolos Giannou could all be given their first caps when Australia face off against Tajikistan on March 24 in Adelaide, or against Jordan in Sydney five days later.

The trio are on the cusp of the final cut and are being monitored by Socceroos' staff over the weekend, with midfielder Bradden Inman also touted in recent weeks as another possible call-up.

While Giannou has been been on the radar after it emerged he had switched his international allegiance from Greece to the Socceroos, the interest in Degenek and Gersbach will create plenty of discussion.
