Top seed Jannik Sinner brushes aside fellow-Italian Lorenzo Sonego, while sixth seed Stefanos Tsitsipas falls to Brazilian qualifier Thiago Monteiro
The entertaining 2-2 draw ensured both sides maintained their unbeaten start after three matches in the final round of qualifying for Russia.
Shamrani struck in the 79th minute, sweeping home from close range just eight minutes after Tomi Juric had finished a well-constructed move to put the Socceroos on the verge of claiming victory.
The fact he was the man who scored the equaliser would have been especially annoying for Australia as Shamrani was a central figure in an infamous confrontation between his club side Al Hilal against Western Sydney Wanderers during the 2014 AFC Champions League final. The home side, roared on by a partisan crowd of more than 51,000, could have even snatched victory in the closing minutes but were denied by a fine save from Australian goalkeeper, Matthew Ryan. The match sprung to life early on when a fine Saudi move resulted in the home side taking the lead in the fifth minute.
Taisir Al Jassim finished smartly from 10 yards after Yehya Al Shehri opened up the Australian defence to secure an early advantage for the Saudis.
Australia overcame their poor start, gradually forcing their way back into the game but it took until the 45th minute for them to draw level.
