Rainfall Monitoring Stations and Records

This page contains links to historic and current rainfall data. Some records extend back to 1921. Most data collection ceased during the war but some has recommenced as a result of commercial developments and publically funded projects including the Water Security Project. As more rainfall data comes to light it will be posted on this page.
