History

Although the suburb of Amaroo is newly established, the history of the land upon which the suburb is situated stretches back at least one hundred and fifty years. Amongst the historic remnants from Amaroo's colonial past is Crinigan’s stone cottage located in Wanderer Court Amaroo.

John and Maria (née Mansfield) Crinigan lived in a stone cottage at this site from about 1842 until 1863. John was a native of Westmeath, Ireland and at 19 years of age was sentenced to transportation for life for “assaulting habitation”. He arrived in the colony of New South Wales

The structure of the rock has been determined by folding. The folds are aligned north-north east and plunge to
the south south west. There are two short faults in the mid south that are marked on the surface by quartz. A
long fault runs parallel with the folding axis along the south east side along Ginninderra Creek determining its orientation.
