Millfield contains a general store and the historic Rising Sun Inn, which now operates as a museum.[3]
Millfield Public School opened in 1868.[4] The school had an enrolment of 62 students in 2015.[5] A second school in Millfield, Crawfordville Public School, operated from 1929 to 1970.[6]
St Luke's Anglican Church was built in 1880.[8] It was flagged for potential closure and sale in June 2018 as part of a diocese plan to raise funds for redress of survivors of child sexual abuse, with services to be consolidated with St John's Church in Cessnock.[9][10] The church had absorbed the congregation of St. Thomas's at Ellalong when that church closed in 2014.[11]
Millfield Cemetery, located in Hayes Road, is managed by the Cessnock City Council.[12]
A new 100-lot residential development, the Rosehill Estate, was released for sale in May 2017. The development was controversial: the original plan for 700 houses did not go ahead, and 500 residents signed a petition against the revised plan on the grounds of overdevelopment of the historic village; however, the rezoning was approved in 2014, with a subsequent council rescission motion lost by one vote. A further 222-block development is proposed off Mount View Road. This has also been the source of controversy, as residents have protested that it could almost double the population of the village.[13][14][15][16]
