Australia have crashed to their heaviest home Test defeat by runs against India in a disastrous start to their bid to reclaim the Border-Gavaskar trophy.

After bowling India out for 150 on day one, Australia were annihilated for the rest of the match, slumping to a record 295-run smashing at Optus Stadium in Perth on Monday.

Following up a dismal 104 - their lowest Test total against India at home for 44 years - Australia showed more fight in their second innings, before being dismissed for 238 soon after tea on day four.
