During the first part of my talk, I will briefly present the first Data Release (DR1) of the SkyMapper Southern Survey. The DR1 covers approximately 20,000 square degrees from the Shallow Survey component, complete to roughly 18 mag in all six SkyMapper filters (uvgriz). This database contains over 2.1 billion photometric measurements for about 285 million unique astrophysical objects, which will serve as the calibration source for upcoming Main Survey component (Data Release 2). The second part of my talk will focus on the SkyMapper follow-up program to search for optical counterparts of gravitational wave (GW) events and fast radio bursts (FRB) found by advanced LIGO/Virgo and Australian-based radio facilities, respectively. The identification of electromagnetic counterpart is essential for improving our current observational interpretation of their astrophysical nature. I will discuss lessons from recent case studies but also introduce our strategy for preparing efficient multi-messenger observations in our next observing run.
