Doolan replaces wicketkeeper-batsman Tim Paine, who has stepped down from the role to concentrate on his own game.

Skipper George Bailey and deputy vice-captain Xavier Doherty will continue in their roles, meaning the entire on-field leadership group of Tasmanian cricket will have originated from the NTCA.

Paine today said he made the decision at the end of last season and says it is completely of his own choosing.

``I made the decision to step down so that I can spend more time concentrating on my own game .'' he said.

``I didn't have the season I would have liked with the bat and as a result I made the decision to step aside and let somebody else take the reins.

``I've given as much as I can to the role and it will be good to have someone with different ideas to lead the team.''

Doolan, 28, said he was honoured to have been appointed to the leadership group.

``I'm really looking forward to working more closely with George and Xavier as well as our coaching staff,'' Doolan said.

''I'm excited to also possibly have the opportunity to lead the Tigers when George is off representing Australia.

``We have a fantastic group of talented players and I have no doubt we can continue to challenge for one-day and first-class titles next season and into the future.''
