We propose real time follow-up observations with the ATCA to search for radio counterparts to candidate gravitational-wave events detected by the LIGO and Virgo detectors. Electromagnetic and gravitational radiation provide complementary views of the Universe: the former being generated by the microphysical processes of charged particles, the latter by coherent bulk motion of masses. A complete picture of the most violent events in nature, such as supernovae and mergers of stellar remnants, will require both types of observation: Gravitational waves (GWs) to uncover the mechanics of the underlying (gravitational) energy source, and electromagnetic waves to reveal how that energy is then dissipated in matter. The search for GWs is entering an exciting phase with kilometer-scale interferometric detectors LIGO and Virgo achieving sensitivities for which detection of GWs is plausible. Since the sensitivity of these instruments improves incrementally, it is likely that the first verifiable detections of GWs will have signal-to-noise ratios that are just barely statistically significant. Observations in the electromagnetic spectrum will help confirm the first GW detections.
