Victorian talent Will Pucovski is a shock inclusion in Australia's Test squad for the two-match series against Sri Lanka in a shake-up that includes the axing of brothers Shaun and Mitchell Marsh as well as Aaron Finch and Peter Handscomb.

Cricket Australia confirmed on Wednesday afternoon that Pucovski, 20, had been included in a 13-man squad and the Marshes had been dropped, as first reported by the Herald.

Pucovski, one of the brightest batting talents in the country, has only played eight first-class matches but made a strong impression in that time, most notably by scoring 243 against Western Australia in Perth in October.

His burgeoning career has been interrupted by a series of worrying head knocks and he has only recently returned from a break from the game that he took to deal with mental health-related illness.
