The 2018 Engagement and Impact reports from the ARC are published on the ARC website (link here).
The results are organised by institution under one tab and by field of research under the other tab. For ACDICT, the field 08 is most relevant: engagement & impact for FOR 08. The results may be subject to debate, but on the face of it they illustrate a different ranking than the usual, and in some cases contrast with the ERA rankings released recently.
