Australian openers Aaron Finch and Usman Khawaja gave their team another solid start of 72 without loss by tea on the fourth day of the first Test against Pakistan in Dubai on Wednesday.
Set a daunting 462-run target to win, Finch remained unbeaten on 39 and with him Khawaja on 32 not out at the break, needing another 390 runs for an unlikely win on a weary Dubai stadium pitch.
If Australia wishes to win this match they will have to rewrite the history books as the highest chase in all Test cricket is West Indies's 418-7, made against Australia at Antigua in 2003.
Pakistan, who were 45 for three overnight, declared 7.5 overs after lunch on 181-6 at the fall of Asad Shafiq's wicket for 41.
Jon Holland, who took the key wicket of Azhar Ali for four on Tuesday, dismissed opener Imam-ul-Haq for 48, caught and bowled off a flighted delivery.
Holland had figures of 3-83 from 20 overs while off-spinner Nathan Lyon took 2-58.
