We discuss the nature of the discrete extragalactic foreground sources at frequencies between 20 and 100 GHz, and their impact on CMB measurements. igh frequency radio surveys areH essential to establish the sample statistics of this class of sources which are strongly under-represented in the existing catalogues at lower frequencies. The difficulties in making higher frequency surveys are discussed nd we describe the new 20 GHz blind survey with thea Australia Telescope Compact Array (AT20G). In addition to characterising the population statistics we can make a real source catalogue which could be used to remove this component of the foreground confusion. Some of our first results which may be relevant to Planck are presented. Note that most of the AT20G data is in an early stage of data reduction and most is not yet published.
