Archaeologists have preserved the outline of the two-roomed ``small miserable hut'' lived in by Mrs Macarthur, and returned the rubble from the hut's fireplace to help school groups visualise and more easily understand the farm's early history.

Last year Ted Higginbotham and his team found evidence of three buildings built during the early-to mid-1800s, including the ``small miserable hut'' described in an 1810 diary entry.

This year they have found three more buildings.

``These finds show us that this area was a focus of activity during the early days of the estate's development,'' Dr Higginbotham said.

``These buildings date from the period we're really interested in 1805 to 1821.''

Artefacts found at the site will help determine what the buildings were used for, who lived in them and their standard of living.

``Once we have catalogued them and recorded that information, the artefacts can then be used for educational purposes,'' Dr Higginbotham said.

``If we can talk to children at this young age and interest them in archaeology and history, then I think that interest is going to last for life.''
