Ashton Agar says he has learned the "game of cricket" over the last four years since he made his last appearance for the Australia Test side.
Left-arm spinner Agar made his debut in the longest format as a 19-year-old in the 2013 Ashes series in England and scored 98 on debut batting at number 11.
However, he did not excel in his primary role of bowling and was axed after two games, never to be seen again in Test whites for the Aussies.
The Western Australia player though is set to play in Australia's first of two Tests against Bangladesh starting in Mirpur on Sunday.
Agar told reporters on Tuesday: "It's just four years of experience. Four years of extra bowling and naturally you get better the more you bowl. I just learnt the game of cricket over the four years playing for WA.
"It's just a lot of time to learn about myself. I worked on all part of my game and that's why I am enjoying."
The Aussies will most likely play two slow-bowlers in spin-friendly conditions and Agar's batting ability should help him edge out Queensland leg-spinner Mitchell Swepson to partner Nathan Lyon in the spin ranks.
Agar continued: "Obviously lot depends on what the wickets look like, but I am ready to go if I get the nod.
"I'm preparing pretty well and I have done everything I can so now I feel like everything is in really good order and now it's really pleasing to be around the Test group.
"It is what you want to do and it's a great bunch of guys to be here around [with]. So it is good fun. I am very hopeful. If he[Lehman] said he is going to play two spinners, I am well placed."
