Verbeek has decided not to call on Michael Beauchamp, Brett Emerton and Harry Kewell, but instead has added David Carney, Bruce Djite, Richard Garcia, Mark Milligan and Matthew Spiranovic to the squad.
Garcia, 26, will make his Australia debut if he takes the field against South Africa.
"This camp is good opportunity for us to see the players after their off-season break," Verbeek said from London.
"Most of the players have just started, or are about to start, their respective domestic competitions and we can now start focusing of the World Cup qualifiers which are just around the corner.
"With that in mind, we will be looking to try a few different things in the match against South Africa on Tuesday night."
