No, I don't think Australia has any hope whatsoever of making the World Cup. The victories by obscene margins were against Pacific Islands who cannot play.
During the qualifying for France 98, Australia gave up a 2-0 lead to Iran to draw 2-2 and therefore lose on away goals, just because play was held up by some fool who deserves to be gassed jumping onto the field and cutting the goal net up, therefore supposedly"disrupting the winning feeling"
You should have heard the bleating shocked commentators. They almost committed hara-kiri in the commentary box.
That said, soccer is not a big sport in Australia, being mainly the sport of ethnic minorities from Europe etc.
