Which places in Western Australia receive the most rainfall?

In Western Australia, the highest annual precipitation occurs in two distinct regions:

• The Extreme North: The Mitchell Plateau in the Kimberley region receives the most significant rainfall in the north.1
• The Extreme Southwest: The area between Pemberton and Walpole, known for its karri (Eucalyptus diversicolor) forests, is the wettest part of the southwest.1

In both of these locations, the mean annual rainfall exceeds 55 inches (1,400 mm). Precipitation levels generally decrease as one moves inland from the coast or away from these two primary zones.1
