Bailey announced his decision today to resign as T20 skipper. The right-hander said he wants to concentrate on the four-day format and improve his chances of playing more Test cricket.
"The very end goal is hopefully to play more Test cricket, but more than that it's just about playing the best four-day cricket I can," Bailey, 32, said.
"It's the format I find the most challenging and the format that I get the most enjoyment from - it's where my real passion lies.
"Whether concentrating on that ends up in me getting back into the Test squad, it doesn't worry me too much.
"It's just about playing as well as I can," he added.
Bailey took over as Australia's T20 captain from Cameron White in 2012. He led the side in 27 games and won 13. He led the team in two editions of ICC World Twenty20 (2012 and 2014). He has played 28 T20Is.
