We have made radio continuum observations with the ATCA (Australia Telescope Compact Array) at 3 and 6 cm of the dark cloud DC 303.8–14.2 in order to study the content of young stellar objects (YSOs) in this cloud. Four unresolved sources were found within the cloud's boundary. One of these in coincident with IRAS 13036–7644, a very low luminosity YSO driving a bipolar molecular outflow. We have interpreted its emission in terms of optically thin thermal free-free emission, although within errors also non-thermal emission is possible. The possible source of ionization is discussed.
