We have entered the age of big data in astrophysics and radio astronomy is no exception. The Australian SKA Pathfinder (ASKAP) conducts wide-field radio surveys of the southern skies. With millions of radio-bright sources in the survey regions we are using new polarisation filtering and positional cross-matching, as well as more traditional variability metrics, to identify interesting astronomical transients. From stellar radio emission to late-time supernova re-brightening, I will speak about some of the different objects we are finding with ASKAP, including the detection of periodic bursts from an ultracool brown dwarf star.
