Abstract　 　　 

　 Pan-spectral astronomy is entering a new frontier with the first coordinated searches for coincident electromagnetic and gravitational radiation sources. With advanced interferometric gravitational wave detectors (LIGO, Virgo, LCGT) we will have the opportunity to probe sources of gravitational-waves that are also expected to be observable via electromagnetic (gamma rays, X-rays, optical, radio) and/or neutrino emission. Coincident observation of electromagnetic and/or neutrino emission could be important evidence in the first direct detection of gravitational radiation. Optical observations will enable localization of the gravitational wave source, and provide powerful new insights into the physics of compact binary coalescence. We summarize the status of the first pan-spectral detection efforts and describe the participation of Australia in the first optical follow-up campaign of gravitational wave candidate events in the LIGO S6 and Virgo VSR2-3 science run. Finally, we summarise strategies being considered in the context of Advanced LIGO science.
