Ishant Sharma is looking forward to prove his worth on Perth's WACA pitch but is not sure what length to bowl on the track renowned as the fastest in the world.

India face Australia in the third Test at Perth starting January 16 and Ishant is excited at the prospect of bowling on the surface.

"I have spoken to my seniors about it and am told it helps fast bowlers a great deal. But I have to learn a lot and am not looking too far ahead of myself," Ishant said.

The Delhi bowler is not sure what length to bowl in Perth but remembers the lessons he has learnt on this tour so far. 

"It is to bowl full length at the start of the innings and then pull it back," he said.

The lanky fast bowler did not feel he has bowled particularly well in the series so far.

"I have bowled well in patches and sometimes I miss my rhythm. Then I ask Dhoni [Images] and other seniors and they all help me."

The 19-year-old paceman impressed everyone with his approach in Sydney even though he finished wicketless, despite the obvious nick from Andrew Symonds [Images] given not out. He looks back at the experience with a tinge of disappointment.

"I wouldn't dwell on the dismissal which didn't happen (the appeal on Andrew Symonds). This is part and parcel of the game, sometimes batsmen are given out when they are not out," Ishant said.

Ishant was the last batsman to fall on the dramatic last day of the SCG Test when Michael Clarke [Images] claimed three wickets in an over to take Australia to their 16th straight Test win.

"I was disappointed I couldn't last in the final minutes of the Sydney game. We should have drawn that game," he said.

Chris Rogers, the left-handed opener tipped to replace the injured Matthew Hayden [Images] in the Australian eleven for the Perth Test, believed it would be a good experience for the Indian bowlers to bowl at WACA, especially Ishant.

"If you are tall, WACA is a good place to bowl. He would enjoy the experience even though Australia has as good a batting line up as any one.

"It's also a bit different bowling at WACA. You have to change the length a bit, and it would be important how they bowl into the wind. That is always one of the biggest test for a fast bowler," the Western Australian said.
