We introduce the TANAMI program (Tracking Active Galactic Nuclei with AustralMilliarcsecond Interferometry) which is monitoring an initial sample of 43extragalactic jets located south of -30 degrees declination at 8.4 GHz and 22GHz since 2007. All aspects of the program are discussed. First epoch resultsat 8.4 GHz are presented along with physical parameters derived therefrom. Wepresent first epoch images for 43 sources, some observed for the first time atmilliarcsecond resolution. Parameters of these images as well as physicalparameters derived from them are also presented and discussed. These andsubsequent images from the TANAMI survey are available athttp://pulsar.sternwarte.uni-erlangen.de/tanami/ We obtain reliable, highdynamic range images of the southern hemisphere AGN. All the quasars and BL Lacobjects in the sample have a single-sided radio morphology. Galaxies are eitherdouble-sided, single-sided or irregular. About 28% of the TANAMI sample hasbeen detected by LAT during its first three months of operations. Initialanalysis suggests that when galaxies are excluded, sources detected by LAT havelarger opening angles than those not detected by LAT. Brightness temperaturesof LAT detections and non-detections seem to have similar distributions. Theredshift distributions of the TANAMI sample and sub-samples are similar tothose seen for the bright gamma-ray AGN seen by LAT and EGRET but none of thesources with a redshift above 1.8 have been detected by LAT.
