In this talk I will present results from a survey conducted with the prototype MWA instrument. In this survey almost 60 repeat observations were obtained of an area of sky ~2000 deg2, to a flux limit of >300 mJy. I will present the results of a statistical analysis of the variability of sources within these fields on day, week and year timescales. In will relate this to the current ‘state-of-the-art’ of transient and variable radio surveys, and I will demonstrate how competitive the MWA is at leading an assault on the dynamic low frequency radio sky, in future operations.
