Lleyton Hewitt's first Davis Cup team will be named on Tuesday with new title-winner Nick Kyrgios set to fire in the singles.
Hewitt will unveil his first Australian team since switching from stalwart player to coach ahead of their world group first round tie against USA next month at Kooyong.
Kyrgios and Australian No.1 Bernard Tomic are set to play singles.
Thanasi Kokkinakis won't be considered with a shoulder injury keeping him on the sidelines.
The team got a boost this week with Kyrgios securing his maiden ATP title in France, beating Croatian Marin Cilic in the Marseilles Open final.
Tomic, the world No.21, was most recently eliminated in the first round at Delray Beach in Florida.
While those two are stand-outs for the singles rubbers, Hewitt has kept his plans for doubles under wraps.
Victorian John Peers could be a surprise contenders for a place in the doubles.
A doubles specialist, Peers reached two grand slam finals last year with Scot Jamie Murray.
He's Australia's highest-ranked doubles player at No.9 and could line up with Sam Groth, who he played with in Sydney in January, reaching the quarter-finals.
Other options include John Millman, James Duckworth and veteran Chris Guccione.
Kyrgios hasn't played Davis Cup since July last year, when the Canberran went down after a poor performance in his lone singles clash against Kazakhstan.
With Australia down 2-1 he was subsequently pulled from the reverse singles in favour of Groth, the home side going on to win the tie 3-2.
After a turbulent few months he was not considered for the semi-final against Great Britain in September which Australia lost 3-2.
The US team will more than likely contain John Isner, Jack Sock, Sam Querrey and the Bryan brothers, Bob and Mike.
