We present the far-infrared derived dust properties from Herschel SPIRE ofthe WiggleZ kinematic sample of 13 star-forming galaxies at z~1.3, withexisting ancillary ~kpc resolution integral field spectroscopy. We detect 3galaxies individually and place limits on the remainder by stacking. Thedetected galaxies, two clumpy discs and one merger, have cold dust temperaturesof ~26 K and have infrared luminosities of ~1.2x10^12 solar luminosities,determined by modified blackbody fitting. The two detected disc galaxies havethe largest H\alpha surface areas of the sample and have the reddestultraviolet to near-infrared spectral energy distributions. The likely sourceof the infrared luminosity in these objects is dust heated by the interstellarradiation field and young stellar emission from the clumps within the discs.The source of infrared luminosity for the merger is likely a dust heated by astarburst resulting from the merger. The WiggleZ detections are among thecoldest and lowest luminosity individual objects detected in the far-infraredat z>1. When combining the kinematic data, we find that none of the compactgalaxies nor the 'dispersion dominated' galaxies of the WiggleZ kinematicsample are detected, implying that they have warmer dust temperatures. Thecompact objects show the highest H\alpha velocity dispersions in the sample, inqualitative agreement with bulge formation models. These far-infrared resultsstrengthen the interpretation that the majority of galaxies in this sampleconstitute different stages in clumpy disc formation as presented fromancillary kinematic analysis.
