Killarney Station was established by Eric Izod with managing partner Ivor Hall in 1953.[1]
Bill Tapp purchased Killarney following talks with Izod and Hall about buying Killarney Station in 1960. Tapp paid £90,000, a Northern Territory record price for a cattle station at that time. He received title to Killarney in 1962.[2]
The Tapp family properties, including Killarney Station, went into receivership in 1991.[3] Brian Oxenford's Western Grazing Company purchased the property.
Wallco acquired Killarney in 2001 from Western Grazing Company.[4] The property was being run in conjunction with neighbouring Birrimba Station, forming an aggregation with an area of 5,515 square kilometres (2,129 sq mi) that was supporting a herd of 41,000 Brahman cattle.
In 2012 the property was run by Wallco Pastoral Company until it was placed in receivership by the National Australia Bank before a refinancing.[5]
Killarney was sold in 2014 to the Jumbuck Pastoral Company for about A$35 million. At the time it occupied an area of 2,819 km2 (1,088 sq mi).[6]
Most of Birrimba and a small portion of Killarney were burnt out by a bushfire in 2014.[7]
