Abstract: There is an immense, internationally significant collection of radio astronomy data in Australia, generated by organisations such as CSIRO and ICRAR, which are also playing an active role in building the Square Kilometre Array (SKA). Australia has constructed two of the three official SKA pathfinders: the Australian SKA Pathfinder (ASKAP) and the Murchison Widefield Array (MWA), so the collection of data will grow in the near future. Commonwealth (Super Science) has made a considerable infrastructure investment to support Data Intensive Sciences within the Pawsey Supercomputing Centre (Pawsey), MWA and ASKAP. The scientists use the co-located high performance compute and data stores to facilitate the research. Research Data Services (RDS) is an investment to support Data Intensive Sciences, such as e.g., MWA GLEAM survey, by providing an infrastructure to store large datasets. RDS already hosts many PBs of MWA data. The Astronomy Data Services (ADS) project has developed a solution to provide public access to astronomy data stored on RDS infrastructure. Together with IVOA services, such as TAP, SIAP and ADQL, JPEG2000 encoding for imagery data, and the consecutive streaming client-server visualisation using JPIP protocol have been enabled.
