The Socceroos opened their tournament with a 4-1 defeat to France on Tuesday, but the manager is likely to resist the temptation to shuffle his pack for what should be a more even match.
Arnold certainly has the players to change shape this weekend, but it is again expected to be a 4-1-4-1 formation, with Celtic's Aaron Mooy operating in a deeper midfield position.
Craig Goodwin made the breakthrough against France last time out and will again feature in an attacking area, with Mathew Leckie, who has 13 goals for the national side, playing on the opposite side.
Mitchell Duke should again lead the line in this Group D fixture, with the 31-year-old looking to add to the eight goals that he has already managed in an Australia shirt.
There will be familiar faces in the shape of Stoke City's Harry Souttar and Middlesbrough's Riley McGree, while Jackson Irvine, formerly of Hull City, should also retain his spot in the side.
Jamie Maclaren did not feature against France despite scoring eight goals for the national side, and the 29-year-old will hope to be involved in some capacity in the team's second match of the tournament in Qatar.
Australia possible starting lineup: Ryan; Atkinson, Souttar, Rowles, Behich; Mooy; Leckie, Irvine, McGree, Goodwin; Duke
