In all seriousness, Australia and other slams only gained their "slam" status in 1933.
Since then, the competition level at this slam has been weak with the exception of the 1960s and early 70s and from 1988 to now.
60s and early 70s was strong because Margaret Court was the dominant player of that time. Plus, Australia also had a lot of top female players during that time aside from Margaret.
1988 was a turning point for this tournament because it moved to a different location and different (unique) surface. All the top female players played in that 1988 tournament and it has continued until now with rare exceptions like injuries or careers winding down.
