We present the results of a continuum snapshot survey of a region of the Large Magellanic Cloud including the area of the giant molecular cloud and the 30 Doradus nebula. The observations have been carried out with the Australia Telescope Compact Array (ATCA) at 1.4 and 2.4 GHz. Most fields are complete to about 6 mJy peak flux density at 1.4 GHz and to about 3 mJy at 2.4 GHz. The positions, peak and integral flux densities of 113 compact () sources detected at 1.4 GHz and of 70 sources () detected at 2.4 GHz are presented. Positions are accurate to about 3″ and peak flux densities are accurate to about 10% or better, depending on the source position relative to the pointing centers. 32 of the sources detected at 1.4 GHz are coincident with Hα objects in the catalogue of Davies et al.; these are possibly intrinsic to the LMC. However, we suppose that most are background objects, since the number vs. flux agrees with predictions of extragalactic source counts from other surveys.
