The ARC has released the tiered journals lists for ERA Physical, Chemical and Earth Sciences (PCE) and Humanities and Creative Arts (HCA) clusters. You can download an excel version of either unique journals with all associated FoR codes in one record or complete journals broken down on a discipline (FoR code) basis. Further revisions of these lists are planned for the future.
These will be useful when deciding where to submit your articles for publication.
