The Australian domestic soccer season is finishing this weekend. This is known as the “A” League. That is A for Australia- not A for quality.
There are other leagues associated with the Australian domestic football; W league which is the Womens version and various representative competitions.
The most prestigious competition that happens regularly in the region is “The Asian Champions League” whereby top Australian clubs play top clubs from the Asian region.
Australia previously competed with South American countries but the Asian pool more reflects the skill set of Australian Football.
