I was looking up poddy mullet on the NSW and QLD Fisheries sites, and here is what I have found.
The NSW website states:
http://www.dpi.nsw.gov.au/fisheries/...s/poddy-mullet
"The term "poddy" refers to the juvenile of a particular species. Poddy mullet are very popular with anglers for use as live bait, especially in estuaries and around river mouths for flathead and off the beach when targeting tailor and mulloway/jewfish. However, it is difficult to identify the various species of mullet, particularly when they are juveniles. As a result anglers may take any species of mullet, for use as live bait only, provided they are less than 15cm and the total number does not exceed 20."
The QLD website states nothing about species ID and refers to sea mullet as poddy mullet, which if you go by the NSW definition is any juvenile mullet:

In the size limits in QLD it refers only to diamond scale and sea mullet, which by their definition can go by the name of poddy mullet.

QLD size limit on mullet - 30cm.
So how does this ambiguity in QLD fare when you get pulled up with a dozen or so live poddys in the bucket or bait tank in QLD?
