My boss has just (this weekend) driven two turtle back to Albury to be released in the Murray. Both had damaged shells and have been recovering at a vets somewhere on the north shore, apparently a long process as they had been there for 15 months.
They were a decent size approx 350mm long (just the shell).

As Numpty has said eastern longneck turtles are fairly common around "The Shire" we've had them on our front lawn.
