We present HI imaging of the galaxy group IC 1459 carried out with sixantennas of the Australian SKA Pathfinder equipped with phased-array feeds. Wedetect and resolve HI in eleven galaxies down to a column density of$\sim10^{20}$ cm$^{-2}$ inside a ~6 deg$^2$ field and with a resolution of ~1arcmin on the sky and ~8 km/s in velocity. We present HI images, velocityfields and integrated spectra of all detections, and highlight the discovery ofthree HI clouds -- two in the proximity of the galaxy IC 5270 and one close toNGC 7418. Each cloud has an HI mass of $10^9$ M$_\odot$ and accounts for ~15%of the HI associated with its host galaxy. Available images at ultraviolet,optical and infrared wavelengths do not reveal any clear stellar counterpart ofany of the clouds, suggesting that they are not gas-rich dwarf neighbours of IC5270 and NGC 7418. Using Parkes data we find evidence of additional extended,low-column-density HI emission around IC 5270, indicating that the clouds arethe tip of the iceberg of a larger system of gas surrounding this galaxy. Thisresult adds to the body of evidence on the presence of intra-group gas withinthe IC 1459 group. Altogether, the HI found outside galaxies in this groupamounts to several times $10^9$ M$_\odot$, at least 10% of the HI containedinside galaxies. This suggests a substantial flow of gas in and out of galaxiesduring the several billion years of the group's evolution.
