The Crystal Palace captain continues to receive treatment for a groin problem, while the star New York Red Bulls forward arrived in camp to join in with preparations
After three rigorous days of training at Central Coast Stadium, coach Ange Postecoglou gave most of his squad a recovery day to recharge the batteries for another gruelling week of preparations.
Only the players who arrived into camp in the last couple of days – Tim Cahill, Mathew Leckie, James Holland, Ben Halloran and Alex Wilkinson – were required to train.
The day off also allowed the likes of Curtis Good (hip), Adam Sarota (groin) and Mile Jedinak (groin) to continue their treatment for their respective injuries.
It came as a welcome respite for the rest of the squad who have been pushed to their limits over the opening few days in camp.
The players took to the water at Terrigal Beach for about 20 minutes, then completed a series of stretches under the supervision of the team's fitness staff.
The down-time is vital for the squad, with training expected to ramp up once the remainder of players come into camp.
Postecoglou plans to have his side as one of the fittest teams at the World Cup, to be able to implement his high tempo, pressing game.
It means the squad will endure many more intense training sessions in the lead up to next Monday's friendly against South Africa in Sydney and when they get to Brazil.
The Socceroos will remain in camp on the Central Coast until Wednesday night, when they shift base to Sydney before the farewell game against Bafana Bafana.
