G'day again PoppaGator.

PoppaCroc? Hmmm.

Kakadu, probably still the biggest of the Northern Territory's National Parks and adjacent to Arnhem Land, is blessed with a number of rivers, full of crocodiles (mostly "salties", Crocodilus porosus) and there are a few places where there are "freshies" or Johnson River crocodiles (C. johnsonii), which are smaller and 'safer'. But the two biggest rivers there are the Alligator River and the East Alligator River, so named because the naming was done by some Pom aboard HMS Alligator in (I think) the 1830s. Given we have no alligators (they're all in the New World) it gets very confusing for tourists.

Bringing the thread drift back closer to the notion of naming, grandparents get called lots of 'familiar' and 'diminutive' names; Poppa is one I'd associate with the US more than with anywhere else, although it's not uncommon here in Oz. Perhaps this is because I associate the parental familiars "Mom" and "Pop" with the US, whereas in Oz it's usually "Mum" and "Dad"; I suspect the later is the most common usage in the UK too.

This leaves the field open to "DaddyCroc" as your Oz equivalent, pace the Oz rock band "Daddy Cool"!
