.. an afterthought after i had fixed the above .. lol, Mooroopna is such a cool name it had to be of Aboriginal origin ..
The name Mooroopna was used by the original Kaieltheban tribe living in the area and meant 'deep water hole'. This refers to a very deep part of the Goulburn River behind the old Mooroopna Hall. The Kaielthebans (population 50 in 1841) were part of the Bangerang race living in the region before the arrival of Europeans.
