We report the spectroscopic confirmation of 29 new, 12 plausible, and 3previously known quasars behind the central ~1.5 deg^2 region of the SmallMagellanic Cloud. These were identified in a single 2df/AAOmega observation onthe Anglo-Australian Telescope of 268 candidates selected primarily based ontheir mid-IR colors, along with a smaller number of optically variable sourcesin OGLE-II close to known X-ray sources. The low detection efficiency waspartly expected from the high surface density of SMC as compared to the LMCtargets and the faintness of many of them (149 with I>20 mag). The expectednumber of I<20 mag quasars in the field is ~38, and we found 15 (22 withplausible) or 40% (60%). We did not attempt to determine the nature of theremaining sources, although several appear to be new planetary nebulae. Thenewly discovered AGNs can be used as reference points for future proper motionstudies, to study absorption in the interstellar medium, and to study thephysics of quasar variability with the existing long-term, highly cadenced OGLElight curves.
