the outback. The mineral collection at Battery Hill is a must-see, although the stamp battery ceased working in 2005, but has since been refurbished and now operates daily for tours. The exhibition 'Freedom, Fortitude and Flies' in the social history museum at Battery Hill tells the story of mining in Tennant Creek through the eyes of women and children. It was designed by award-winning artist Alison Alder, a former Tennant Creek resident. Aboriginal enterprises and organisations generate economic activity for Tennant Creek by providing a range of services to the urban and rural communities of the town. Nyinkka Nyunyu Arts and Cultural Centre opened in July 2003, offering visitors and the community an opportunity to learn about Aboriginal life, history and culture. Transport Tennant Creek has been accessible by train since the completion of the Adelaide-Darwin railway north from Alice Springs in 2004. The Ghan, run by Great Southern Rail between Adelaide and Darwin, passes twice weekly in each direction. Tennant Creek is serviced by Tennant Creek Airport, with scheduled flights to Alice Springs and Darwin. Outback Airlines currently services Tennant Creek, providing mining charters between Alice Springs and Tennant Creek with seats available to the general public. Tennant Creek has daily coach services from Darwin, Alice Springs, and previously Queensland (closed due to COVID-19). The Barkly Tablelands are best explored via Tennant Creek, which can be accessed on the fully sealed Explorer's Way, 1,000 kilometres south of Darwin, 670 kilometres south of Katherine and 510 kilometres north of Alice Springs. The Overlander's Way (Barkly Highway) is another tourism drive from Queensland that meets the Explorer's Way at Threeways – 25 kilometres north of Tennant Creek. In May 2005, Minemakers and ATEC signed an agreement to study a 250 km open access railway from Tennant Creek to Wonarah. Historically, there has been suggestion of a rail link between Tennant Creek and Mount Isa. This link would allow resources companies to gain access to both the Adelaide-Darwin (The Ghan) and Townsville-Mount Isa (The Inlander) lines. The missing rail link would also provide rail passengers with direct rail access to Darwin from the East Coast of Australia. The Australian Defence Force may also use the link to provide a rail access between the 1st Brigade in Darwin, and the 3rd Brigade in Townsville. Education Tennant Creek has a primary and high school. In the 1970s and '80s, secondary students tended to leave
