Scotland had qualified for the play-off by finishing second in their UEFA group, behind Spain. Scotland secured second place in dramatic circumstances with a 1–1 draw against Wales at Ninian Park, Cardiff. Davie Cooper scored a late equalising goal with a penalty kick to give Scotland the point they needed, but manager Jock Stein collapsed and died of a heart attack. This meant that assistant manager Alex Ferguson took charge of the team for the play-off.
Australia finished top of a single four-team group that comprised New Zealand, as well as Israel and Chinese Taipei, both of whom were at the time members of FIFA but were outside their own regional confederations.
In the first leg of the play-off in Hampden Park on 20 November 1985, Scotland took the lead in the 53rd minute from a twenty-yard free kick scored by Davie Cooper, hitting the ball around the wall and into the bottom right hand corner of the net. The second goal arrived in the 59th minute from Frank McAvennie who was making his senior debut for Scotland. He lobbed the ball over the goalkeeper after being set up by a header from Kenny Dalglish. The second leg on 4 December finished goalless which was enough for Scotland to advance to the 1986 FIFA World Cup finals in Mexico.
