The college for which I teach, Melbourne School of Theology (MST), publishes a rather new journal called Paradosis, devoted to biblical and theological topics. Its second volume, published in 2015, was dedicated to the Psalms, and is now available on our college website.
The best-known authors featured from a scholarly point of view are probably John Olley (Vose Seminary, Western Australia) and Michael Theophilus (Australian Catholic University, Melbourne). Also featured are articles by Edward Woods, author of the Deuteronomy volume in the Tyndale OT commentary series and editor of the volume, Katy Smith (Bible College of South Australia), John de Hoog (Reformed Theological College, Geelong, Victoria), Gillian Asquith (also MST), David Cohen (Vose Seminary) and myself.
So there’s no Susan Gillingham or J. Clinton McCann, but you might find it a worthwhile read, particularly if you’re looking for insights on a particular psalm. Specially featured psalms include 89, 119, 137 & 148. Why not have a browse?
