In this paper we report and discuss the results of a radio survey in the A3571 cluster complex, a structure located in the Shapley Concentration core, and formed by the three clusters A3571, A3572 and A3575. The survey was carried out simultaneously at 22cm and 13cm with the Australia Telescope Compact Array, and led to the detection of 124 radio sources at 22cm. The radio source counts in this region are in agreement with the background counts. Among the 36 radio sources with optical counterpart, six have a measured redshift that places them at the distance of the A3571 cluster complex, and nine radio sources have optical counterparts most likely members of this cluster complex. All of the radio galaxies emit at low power level, i.e. P_22cm_<=10^22.6^ W/Hz. A number of them are likely to be starburst galaxies.
