We are located on the sixth floor of the Carslaw Building in the University of Sydney. Drop by room 618 if you want to visit in person. Please do not contact the administrative staff of the School of Mathematics and Statistics. The Magma group is a separate entity.
Please note that the Magma administrative office is staffed on a part-time basis so that a few days may elapse before you get a response. Note that requests for changes of MAC address, or a setting a new password are normally given priority.
