Fresh from hitting the winning runs for the Queensland Bulls in the Sheffield Shield Final where he scored an unbeaten 81, Renshaw was bound for South Africa to join the Test squad.
Burns was left to celebrate the Shield win with his Queensland teammates before receiving a late call on Tuesday night informing him of his selection.
Burns and Renshaw will join Glenn Maxwell in the Australian Test squad in place of Steve Smith, David Warner and Cameron Bancroft as the fallout from the Australian ball tampering saga continues.
The call up and flight across the Indian Ocean will cap a whirlwind 24 hours for Renshaw who will be unable to celebrate the Shield win as he packs his bags before turning 22 as he lands in South Africa.
Both Burns and Renshaw have enjoyed fruitful 2017-18 campaigns across all formats, with the former hitting his maiden first-class double century in December, while also starring for the Heat in BBL|07. Renshaw's end of season form saw him top the Shield run-scorers list with three centuries in three games leading into the final.
