Recent research determined that the silver trevally in south-eastern Australian and northern New Zealand waters is distinct from the larger tropical form (Pseudocaranx dentex) and the old name (P. georgianus) has been restored. Silver trevally occur in estuarine and coastal waters of southern Australian states ranging from about Coffs Harbour in NSW to about Perth in WA. The depth range for this species is 0-200 m, but is more common to 25 m. Most of the Australian commercial catch is taken in NSW and eastern Victoria. Silver trevally is a schooling species, inhabiting mainly sandy substrates (Wilson et al. 2009).

The stock structure of silver trevally off Australia is poorly understood, but there are some indications that a south-eastern Australian stock may be present, and distinct from the New Zealand North Island distribution, although its boundaries are not clear (AFMA, 2012).

Silver Trevally are caught by Commonwealth and state trawlers, and state-based trap, longline, mesh net, haul seine and purse seine vessels. Overall, most of the catch is taken by fish trawling (Wilson et al. 2009).
