Australia will need to produce a record-breaking sub-continental run chase for an unlikely victory on the final day of the third Test against Sri Lanka in Colombo.
Sri Lanka set an imposing victory target of 324 runs after Angelo Mathews declared at 8-347 in their second innings early on Wednesday after resuming on 8-312.
Dhananjaya de Silva finished on 65 not out to go with his match-turning 129 in the first innings while Suranga Lakmal was unbeaten on four.
The only time Australia have successfully chased 200 or more in Asia was against Bangladesh in 2006 when they made 7-307 in the first Test in Fatullah.
Australia will have a minimum of 83 overs to reel in the target.
