Actually, the most recent _Megalania_ work would be that of Ralph Molnar.
Dr. Molnar found 320kg to be about the average size of the _Megalania_ specimens currently known, with the largest individuals hitting 7 meters and 920kg.
Total length estimates in particular will depend largely on the length of
the tail, which lacking any complete fossil specimens will usually be
conjecture. Mass is probably a better way of comparing 'size', since a tail
ending with a long thing whip-like structure won't increase the mass much,
but could potentially add a metre or three to the total length.
Earlier one-tonne-plus mass estimates (Auffenberg gave the heaviest, at 2.2
tonnes) were almost certainly incorrect. I haven't read Molnar's book, but
I'd be interested to know which specimens gave the 7m length estimate. Hecht
gave a similar length estimate in 1975, which he extrapolated from a single
