We present two large, nearby (0.013$\le$z$\le$0.06) samples of Early-TypeGalaxies (ETGs): a visually classified sample of 220 ETGs, created usingsource-matched data from the Galaxy and Mass Assembly (GAMA) database withFIR/sub-mm detections from $Herschel$-ATLAS; and a visually classified sampleof 551 ETGs which are undetected with $Herschel$-ATLAS. Active galactic nuclei(AGN) are removed from our samples using optical emission line diagnostics.These samples are scrutinised to determine characteristics of sub-mm detectedversus undetected ETGs. We find similarities in the stellar mass distributionsof the two ETG samples but testing other properties uncovers significantdifferences. The sub-mm detected sample is shown to have lower concentrationand S\'ersic indices than those in the undetected sample - a result which maybe linked to the presence of dust in the former. Optical and UV-optical coloursare also shown to be much bluer, indicating that the dust is linked with recentstar formation. The intrinsic effective radii are on average 1.5 times largerfor the sub-mm detected ETGs. Surface densities and groups data from the GAMAdatabase are examined for the two samples, leading to the conclusion that dustyETGs inhabit sparser environments than non-dusty ETGs in the nearby universe,although environments of the brightest ETGs are shown to differ the least.Modified Planck functions are fit to the H-ATLAS detected PACS and SPIRE fluxesfor ETGs with sub-mm flux densities of at least 3$\sigma$ in the 350$\mu$mSPIRE band, giving a resultant mean cold dust temperature of T$_{d}$=22.1K,with a range of 9-30K. The corresponding mean dust mass is1.8$\times10^{7}$M$_{\odot}$, with a range of(0.08-35.0)$\times10^{7}$M$_{\odot}$. The dust masses calculated from thesefits, normalised by stellar mass, are shown to increase with decreasing stellarmass and bluer colours.
