Cricket Australia's head of national teams Ben Oliver says the game needs to better understand the effect the sport's "relentless schedule" has on the mental health of players after Will Pucovski's withdrawal from Test selection.

The Victorian youngster, who was on the verge of being picked for his Test debut, became the third player in as many weeks to announce he will take a break from the game, alongside Glenn Maxwell and Nic Maddinson.

Pucovski has been praised by senior CA figures, who have applauded him for having the courage to put aside his personal ambitions to concentrate on his mental wellbeing.

The recent withdrawals have highlighted that cricketers are no different to others in the community in being susceptible to mental health issues.
