The paper ‘Discovery of H i gas in a young radio galaxy at z = 0.44 using the Australian Square Kilometre Array Pathfinder’ was first published in MNRAS, 453, 1249 (2015). In this erratum, we correct the X-ray luminosity given for PKS B1740−517 in Section 4.2.1. The luminosity was incorrectly calculated as 4.3 × 1043 erg s−1 from a simple absorbed power-law model fitted to the XMM–Newton data. The correct value for this model is L2–10 keV ≈ 6.2 × 1044 erg s−1.

This erratum does not change the conclusions reached by Allison et al. (2015) and is still consistent with the distribution of X-ray luminosities measured for other GHz-peaked spectrum (GPS) radio sources (e.g. Tengstrand et al. 2009).

We thank Roberto Soria and Ryan Urquhart for bringing this error to our attention.
