Perform or perish in the Baggy Green

As Australia's selectors continue to employ the "horses for courses" strategy, there is now more pressure to perform immediately for the specialist players who are drafted in when conditions suit.

Australia today announced their 14-man squad for the two-Test tour of New Zealand next month, including seam bowlers Jackson Bird and Chadd Sayers to exploit the expected fast bowler-friendly conditions across the Tasman.

While Bird says he won't put any extra pressure on himself if he's selected for his fourth Test, he knows how important it will be to perform given his specific selection and Australia's strong fast bowling stocks.

"Being in the Australian team is a cut-throat environment; you've got to perform straight away in whatever conditions you're playing in simply because of the wealth of talent we've got going around," Bird told cricket.com.au.

"I'm not going to try to put any extra pressure on myself if I play.

"In conditions that are seaming around I try to keep things as simple as possible – just try to stand the seam up and put the ball in the right area and the ball usually does the rest for you.

"I've played in a lot of seaming conditions down in Tassie and I think that suits me well."

And Bird is an advocate for the horses for courses mantra.

When Australia tour the subcontinent an extra spinner, and allrounder Glenn Maxwell, are often included, while at home on benign batting pitches pure pace is preferred.

"You need players who suit different types of conditions," said Bird, a line and length bowler who tops the speed gun in the high 130kph region.

"There's no point in picking someone like me to bowl in India where you need guys to bowl 145kph-plus.

"I think it's a good thing that they're picking players for certain conditions and it's beneficial to the team as well."

Quick Single: New calling for old-fashioned Chadd

Peter Siddle, who returns to the Test squad as he recovers from an ankle injury he suffered last month's Boxing Day Test, expects to see more specialist selections moving forward.

"With a lot less experience now around the Australian setup, they (the national selectors) will be looking for players to perform straight away in those conditions," Siddle said.

"We don't have the luxury as much at trialling blokes and letting them get a few Tests and getting comfortable in the Test arena with all the different wickets we do get tossed up.

"It's going to happen (conditions-specific selections), New Zealand is probably the start of it and we'll see what happens in the next 12 months with the different tours and back home here."

Australia carried the same fast bowling attack of Mitchell Johnson, Mitchell Starc and Josh Hazlewood for the first four Tests of last year's Ashes series, thriving on the flat wickets in Cardiff and at Lord's, but struggled when the curators in Birmingham and Nottingham kept grass on the pitch to suit England's seamers.

Siddle, who relies on hitting an immaculate line and length, came in for the final Test at The Oval to replace Hazlewood and starred, taking six wickets for the match in the consolation win.

While Siddle does not possess the raw pace of some of his peers, he is effective on wickets that encourage seam and swing bowling, and that's the type of surface he expects to face in New Zealand.

"The Ashes and the day-night Test in Adelaide are good examples of what we're going to encounter over there (in New Zealand)," Siddle said.

"We have to be prepared for the ball to be swinging and seaming around a bit as a batting unit.

"And with the ball, doing the same things (as the Black Caps bowlers) back to them (New Zealand) and that's what we've got to be good at."
