It is interesting to compare sizes from different authors. Steve Wroe now claims 4.5 metres, the Australian Museum in Sydney had a life-sized replica blow-up at the main entrance on the roof and that was over 20 odd feetin length.
A show on Megalania interviewed Dr Ritchie from the Australia Museum who claimed Megalania was only 8-12 feet in length. How, if the Komodo specimens have been found larger than that at the extremes and averages 10 feet.
The Composite skeleton at the Queensland Museum and the head in the exhibition show Megalania to be at least 12-16 feet on average. As with any species larger specimens are known.
Look at Krys, the almost 30 foot long Croc that was shot. Now the average croc is only 2-3-4 metres in length, yet here we have a 28 foot version. Are we to say that was just the only one of it's size. If Megalania or a related form or evolved form still exists, and I believe they do they a 50 foot or larger specimen-as in Aboriginal/Koori legends cannot be discounted.
Extinction was caused by lack of food etc..yet giant crocs can eat one meal for a whole year in extreme cases so why Not Megalania. As food went scarce it went into survival mode and slowed down everything.
Many animals and marine creatures do this. Frogs...salamanders..

GIGANTIC AUSTRALIAN DRAGON LIZARDS: Megalania prisca is a Goana weighing over 4000 pounds, and dwarfing the Komodo monitor lizard by a factor of five.
At over 30 feet in length, this nightmarish predator fed on hippopotamus sized marsupial wombats, rhino-sized herbivorous diprotodonts, and several large mega-kangaroo species (11.5 feet tall) in Australia, and approximately 40-60,000 years ago, began preying upon the first human colonists to reach Australia and the indonesian Islands.
Approximately 8-10,000 years ago, the climate changed and while the humans and smaller marsupial species continued to thrive, the giant lizards could no longer sustain themselves and most starved and stopped breeding.
As large as they were, they would have been ambush hunters, hiding then running down small prey, gashing and following the easier to hunt larger prey as it sickened from the infected wounds. If they are extinct, the primary cause was the loss of their large game prey.
The smaller, faster marsupial ground species could hide more easily in the heavy brush, meaning not only smaller meals but fewer ones as well. Aborigines would have learned how to avoid and escape them after only a few generations of having been eaten by these largest of lizards in history.
Coordinated bands of hunters could also have engineered traps and ambushes designed to rid themselves of the menace of being eaten by Megalania prisca, perhaps eating their meat as well. This would also have been true for the larger crocodilian species as well.
