Bells Phase Lace Monitor? Visually larger, but in the vicinity of two other clearly adult lace monitors in the more common form and also at least one younger one also in the more common form. All within about 100m of each other. Maybe (?) sharing pooled water after the heavy rains just before the 7th of November. This lizard and one of the adult common forms both drank from the same pool within an hour of each other. That's probably all of my observations.
Brilliant record! Well done. Great photographs. Your comments on the three individuals seen are useful. Good to hear from you that they are still managing to breed successfully. That little patch of forest/woodland would be very important to this declining species. As you mention, the Bell's Form is uncommon in this region and does not occur east of the Great Dividing Range.
