Defender Robert Cornthwaite redeemed a first-leg own goal to crown Adelaide United as the first Australian team to reach the last four of the AFC Champions League on Wednesday night.

Adelaide eliminated Japanese champions Kashima Antlers with a 1-0 victory in their second-leg quarter-final at Hindmarsh Stadium, in front of a record 16,965 fans.

Cornthwaite headed the winner in the 73rd minute to erase his agony of netting an own goal in the away tie last week and sent Adelaide United through 2-1 on aggregate.

Adelaide's tense win set up a semi-final with Uzbekistan's FC Bunyodkor in next month's two-legged semi-finals.

Bunyodkor crushed Saipa of Iran 5-1 to go through 7-3 on aggregate.
