We present the set of extragalactic sources detected in a 455 square-degree map of the southern sky made with data at frequencies of 148 GHz and 218 GHz from the Atacama Cosmology Telescope (ACT). I will discuss the ACT survey and properties (e.g., spectral indices and differential counts) of these source populations. I will also discuss a follow-up study with the Australia Telescope Compact Array to better characterize these populations in a frequency/flux regime that is only now being explored thoroughly. Effects of these populations in the context of the high-ell CMB secondary anisotropy power spectrum and on SZE cluster surveys are explored.
