Australian captain Tim Paine has addressed speculation over whether Steve Smith will again lead the team once a ban ends in March, saying he would be fully supportive if it happens "one day". <p></p> <p></p>Smith skippered the team until he was suspended for 12 months over a brazen attempt under his watch to alter the ball with sandpaper in Cape Town last year. <p></p> <p></p>Part of his punishment included a further year-long exile from any leadership role. <p></p> <p></p>Calls have grown for Smith to take over from Paine when the ban is lifted, following batting performances that helped Australia retain the Ashes against England. <p></p> <p></p>Paine, who will turn 35 in December, on Monday brushed off questions surrounding the Australian side's future leadership. "I'm enjoying having the job at the moment... and I certainly hope Steve Smith does captain Australia again one day, and if he does, I'll be fully supportive of it," he told the Daily Telegraph. <p></p> <p></p>Paine will not play in this summer's Big Bash League, instead joining broadcaster Channel Seven's commentary team. <p></p> <p></p>But he will almost certainly retain the captaincy for the home summer Test series against Pakistan and New Zealand, despite occasional criticism of his form during the Ashes. <p></p> <p></p>He recently ended a 13-year century drought by scoring his first ton since his maiden century as a 21-year-old in 2006. <p></p> <p></p>Coach Justin Langer has praised his leadership as "brilliant" and said Smith may not want to take on the "burden" of the captaincy on top of batting pressures.
