Spinners Bryce McGain, Beau Casson and Jason Krejza are in a three-way race for the vacant spin berth in the Australian Test side after being named in a 14-man squad for Australia A's tour to India.
Simon Katich will lead a squad featuring only one other player with Test experience for the tour from September 3-26.
The start of the tour will clash with the final two matches of Australia's one-day series against Bangladesh, meaning players such as David Hussey, Shaun Marsh and Shane Watson were not considered.
Selectors will consider performances from the two three-day matches at the start of the tour before finalising their squad for the four-Test tour of India in October and November.
The naming of McGain, Casson and Krejza in the squad is the clearest indication yet the trio head the list of names waiting to replace Stuart MacGill and Brad Hogg, who both announced their international retirements earlier this year.
Casson made his Test debut in the third and final Test against West Indies earlier this year, while McGain, despite a career-best season last summer, and Krejza are uncapped at international level.
"Ahead of the approaching Indian Test series Australia have also taken the opportunity to have a look at three spinners in the 14-man squad for the three-day games who are considered exciting prospects," said NSP chairman Andrew Hilditch.
The tour will also allow several youngsters who have starred in domestic cricket in recent seasons to impress at a higher level.
Teenage sensation Phillip Hughes, who made a century in last summer's Pura Cup final, has been named along with Blues team-mate Peter Forrest, Tasmania's George Bailey and Western Australians Marcus North and Adam Voges, who will be vice-captain.
"These young batsmen are all players the NSP considers has the potential to play for Australia in the future," Hilditch said.
Queensland veteran Ashley Noffke will lead a four-man pace attack containing former South Australia paceman Ryan Harris, Blues star Doug Bollinger and rising Bushrangers speedster Peter Siddle.
Luke Ronchi, so impressive in Brad Haddin's absence during the one-day series in the Caribbean, will don the gloves.
Changes will be made to the squad for the four one-day matches against New Zealand A and India A starting on September 15. The final will be played on September 26.
