The Australia Telescope National Facility comprises the Parkes Telescope, Australia Telescope Compact Array, and the Mopra Telescope. The Australian SKA pathfinder (ASKAP), will also be operated as part of the ATNF prior to incorporation in the Square Kilometre Array. I will describe recent scientific results and technical progress at the ATNF, including ASKAP commissioning and phased array feed development and performance, the conversion of the Parkes Telescope to operate under remote control, and results from recent upgrades to the ATCA. I will also review CSIRO activities in support of the SKA project.
