MWA ORGANISATIONAL CHART

Our team's structure

The MWA Operations team is based at Curtin University, 600km from the telescope itself. Together with the MWA Management team, this small dedicated group of people keeps the telescope running every day of the year. See the image below for the MWA's organisational structure.
