Yep, looks like it will pretty much boil down to that.
Assuming we finish ahead in Goal Difference:
- Winning against Japan guarantees qualification.
- Drawing against Japan and a win/draw against Saudi Arabia guarantees qualification.
- Drawing against Japan, then losing to Saudi Arabia means Australia qualifies UNLESS Indonesia wins both of their games AND/OR Saudi Arabia defeat Bahrain
- Losing against Japan means Australia must at least draw against Saudi Arabia - the scenario of us losing to both Japan and Saudi Arabia and still qualifying is possible, if Saudi Arabia have lost to Bahrain, and Indonesia does not win both matches against China and Japan.
I had a bit of downtime, so just wanted to look at outrageous scenarios that could see us fail to qualify on goal difference.
- A draw with Saudi Arabia, alongside a Saudi Arabia victory over Bahrain, and an Australia loss to Japan by a collective 10 goals would see Saudi Arabia finish ahead on goal difference
- Draws in both our games against Japan and Saudi Arabia, alongside Indonesia winning both of their games against Bahrain and Japan by a collective 13 goals (this is a tie on goal difference, but Indonesia would have more goals scored)
