New players, including batsmen Chris Lynn, Travis Head and seamer Andrew Tye, must impress in the three-game T20 series against India starting in Adelaide to make Australia's 15-man World T20 squad.
Batting mentor Di Venuto will steer Australia in the T20 series after head coach Darren Lehmann was diagnosed to be suffering from Deep Vein Thrombosis.
Di Venuto said Australia's 17 hopefuls for World T20 ticket to India during March/April must remain true to their games and they should avoid audition 'stagefright'.
"If they're thinking about the World Cup they are likely to go out there and get a bit of stage fright. They have to play exactly how they have been playing. T20 is all about expressing yourself, backing your ability and taking the game on," he was quoted as saying in 'Daily Telegraph'.

Brisbane Heat skipper Lynn was voted player of BBL with 378 runs at 54.00. Home town duo -- power hitter Head and reborn slinger Shaun Tait -- will be let loose on Australia Day against India, indicated Di Venuto.
"Taity bowls fast and we saw that in the BBL and is still knocking players over. If he can take early wickets that will be huge bonus."
Di Venuto hoped the revamped T20 unit under Aaron Finch's could gel together and nail a breakthrough World T20 title.
"We want to get a bit of momentum. We have some fantastic T20 players who perform well in all competitions but just have not performed as a team when we have got World Cups.
