We report on three target of opportunity observations made of the recurrent nova T Pyx, currently in outburst, using the Australian Telescope Compact Array. We did not detect the source at its well established coordinates in any of the individual observations, nor by combining all three data-sets. The first observation started 2011 April 17.49 (UT) for 1.41 hours on source, giving 3-sigma upper limits of 72 microJy at 5.5 GHz and 103 microJy at 9 GHz. The second observation started 2011 April 20.39 for 1.18 hours on source, giving 3-sigma upper limits of 76 microJy at 5.5 GHz and 108 microJy at 9 GHz. The third observation started 2011 April 23.30 for 2.96 hours on source, giving 3-sigma upper limits of 48 microJy at 5.5 GHz and 65 microJy at 9 GHz. Combining all three data sets yields 3-sigma limits of 35 microJy at 5.5 GHz and 50 microJy at 9 GHz.
