Thats right @abread111 and @HarrietteWilson. This is the individual I tentatively identified years ago as 'RobinLarge' and several other interim names including 'Harriet Wilsons Goanna', 'Peter Laings Goanna', and others.
@HarrietteWilson @DonFletcher Don now knows which goanna this is ... because he has been able to compare it with good photos of the other few goannas on Mt Ainslie/Majura - there are only 7 of them
