Along with high-profile regulars such as Mark Schwarzer, Tim Cahill and Lucas Neill, Osieck included striker Mitchell Duke who impressed on his debut at the recent EAFF East Asian Cup in Korea Republic.
"The main point is to compare where we stand against one of the top teams in the world. From there we can plan our training content and other matters in the lead-up to next year's World Cup," said Osieck.
"To be able to travel to the country that is hosting the World Cup a year ahead is also of great value.
"The players will be able to familiarise themselves with various factors that they will experience next year so it won't be a surprise next June.
"It will also be interesting to see how we are received having to play the host nation in Brazil with a large home crowd."
