Usman Khawaja is backing David Warner to give the world record individual test score a real shake at the Waca tomorrow.
Warner will start day two against New Zealand on 244, his highest test score, and 157 away from eclipsing Brian Lara's world best mark of 400 not out, against England in Antigua in 2004.
Australia will start at 416 for two.
Warner's score is the highest in a single day in a test in Australia, beating the previous mark of 224 by Michael Clarke against South Africa at Adelaide three years ago.
There are just six instances of a batsman making more in a day in test history, a list headed by the legendary Don Bradman's 309 against England at Leeds in 1930.
