We interpret the data on the nearby active galaxy IC 5063 (PKS 2048-57) within the framework of an obscured quasar, as proposed by current unified schemes for active galactic nuclei (AGN). We apply new techniques to estimate the reddening towards the nucleus of obscured AGN, based on infrared photometry and line-to-continuum correlations, and conclude that the previously claimed detections of the transmitted quasar continuum in the H and K bands are probably due to the presence of foreground dust, which results in reddening of the starlight within small apertures. From the data available on this object and established correlations between quasar properties, we deduce the amount of visual obscuration towards the active nucleus in IC 5063 to be in the range A(V) = 65-105 mag.
