History
The establishment of a school was officially approved in February 1881 with tenders called to erect the school building and teacher's residence in March 1881. However, the chosen builder rejected the contract in November 1881, leading to delays in the construction of the school. St Helens State School opened on Saltwater Creek Road on 16 August 1882 under headmaster Robert Barry.
The Agnew School (Maryborough) opened in St Helens on 3 February 2003. It is now known as the Maryborough campus of OneSchool Global.
Maryborough Victory Church was built from brick in 1985.
