  Locally Repairable Codes (LRC's) based on generalised quadrangles were
introduced by Pamies-Juarez, Hollmann and Oggier in \cite{PaHoOg2013}, and
bounds on the repairability and availability were derived. In this paper, we
determine the values of the repairability and availability of such LRC's for a
large portion of the currently known generalised quadrangles. In order to do
so, we determine the minimum weight of the codes of translation generalised
quadrangles and characterise the codewords of minimum weight.
