However, Saudi Arabia rocked the home side with another equalizer deep in first-half stoppage time, when Taiseer al-Jassam's controlled header across the goal was sacked home by al-Sahlawi.
Ryan saved an Al Sahlawi shot at the other end, before the Socceroos fumed when they had a penalty claim turned down after Leckie was taken down by Salman Al Faraj as he raced through on goal.
The snub appears to have overshadowed the fact that the Australian squad ended up beating the Saudi team 3-2 in a crucial win.
"Both the AFC and the Saudi team agreed that the minute of silence could be held", the spokesman said.
The Australians are approaching the match with a series of 7 unbeaten fights, winning three times and four draws in the last meetings.
A spokesman for Football Federation Australia explained they were told a minute of silence was "not in keeping with Saudi culture" ahead of the match.
Australia sit in third spot in the group, three points shy of the Saudis and leaders Japan, with three games remaining.
The top two teams in both the Asian qualifying groups get an automatic spot at Russian Federation 2018, with the third-place teams going into a series of playoffs.
An Islamic Imam Sheikh Mohammad Tawhidi has now explained the rationale behind the decision of the Saudi Arabian players to have done what they did on the pitch.
Swiss-based striker Tomi Juric twice gave the Socceroos the lead in the first half, but both times Saudi Arabia fought back to be level at 2-2 at halftime.
However, as the Independent points out, Saudi club teams have in the past observed moments of silence on the field. In between, the Australians will play at the Confederations Cup in Russian Federation.
Like in most worldwide games this week there was a minute's silence in honour of the victims of the London terror attack at the Adelaide Oval.
