India batter Punam Raut has produced a remarkable piece of honesty on day two of the Test against Australia.

With the tourists were in a good position at 2-217 in the 81st over of their first innings, thanks to Smriti Mandhana's dig of 127, Punam pushed at a Sophie Molineux delivery outside off stump.

The Aussie fielders went up after the ball nestled in the gloves of wicketkeeper Alyssa Healy, but umpire Phillip Gillespie shook his head.

As he did, though, Punam simply walked off the pitch and kept going, all the way to the pavilion, rediscovering the long-lost art of walking in Test cricket.

With no decision review system in place, Gillespie's on-field decision of not out would have stood if Punam had not walked.

The sporting decision was all the more remarkable considering how few opportunities women's cricketers get to play Tests, with this match just Punam's fourth in her 12 years playing international cricket.

If there was an edge, it must have been a very faint one, with short leg Beth Mooney saying she did not think there was anything on it.

This level of honesty is increasingly rare in international cricket, with former Australia wicketkeeper Adam Gilchrist one of the few proponents of walking.
