Holtze is a locality in Darwin, Northern Territory, Australia. It is 22 km southeast of the Darwin CBD. Its local government area is the Municipality of Litchfield. The locality is mostly a rural area, just north of Palmerston. It was named for Maurice William Holtze (1840–1923), the botanist who established Darwin's Botanical Gardens, and his son Nicholas, who succeeded him as curator.[4]
In September 2010, the Northern Territory Government announced that new a Darwin’s prison precinct, Doug Owston Correctional Centre, would be built in Holtze, about four kilometres north of Howard Springs Road.[5] In July 2012, a road in Holtze was registered and named after prison officer Reginald Anthony Willard (1943–1997), who worked at the correctional centre.[6]
In 2011, the Northern Territory Government identified a greenfield site in Holtze near the intersection of Temple Terrace and the Stuart Highway as the location for the Palmerston Regional Hospital. The hospital opened in 2018.[7]
In the 2016 census, there were 1,810 people in Holtze. Aboriginal and Torres Strait Islander people made up 44.4% of the population.
