Agar began his cricketing journey in Victoria, representing the state in underage competitions and later representing Australia at the Under-19 level in several international matches. Seeking better opportunities, he moved from Victoria to Western Australia ahead of the 2012–2013 domestic season. This transition allowed him to make his Sheffield Shield debut for Western Australia in January 2013.
Ashton Agar played for the Australia Under-19 team during a tour of the United Arab Emirates, where they faced the West Indies Under-19 squad. He featured in both Under-19 Test and One Day International formats.
