Milburn has since 2007 been home to the Otago Corrections Facility. This low to high-medium security men's prison, at the northern end of Milburn, is the largest in the Otago Region, housing up to 485 inmates and employing 201 staff.
A large whalefossil can be found in a display at a lookout over the limeworks, Tokomairiro Plains and Lake Waihola.
Milburn was named after Morris Milburn, who came to New Zealand from Sunderland, North East of England in The United Kingdom in 1858. He arrived at Lyttleton harbour aboard The Zealandia. "He journeyed overland to Dunedin doing the greater part of the trip by foot. In Otago he followed the goldfields with varying fortune incidental to a miners life. Working successfully at Gabriel's Gully at Molyneux and at Milburn, the last mentioned place being named after him" Exert from Morris Milburn's Obituary from The Lyttleton Times December 1906, accessed from Papers Past.
