Regional City Seeks Return to Rail as Flight Options Shrink

As regional air services contract across parts of Australia, the city of Mount Gambier in South Australia is advancing plans to revive passenger rail connectivity as a sustainable alternative for commuters and regional travelers.

Mount Gambier, located on the state’s Limestone Coast and historically served by rail until passenger services ceased in 1990, is now positioning the restoration of rail links as a strategic response to declining flight options and rising demand for reliable public transport. Local officials and transport advocates argue that reinstating rail could reduce reliance on costly and infrequent air services while supporting regional economic development.

The push comes amid broader scrutiny of air service viability in regional Australia, where several routes have been suspended or reduced in recent years due to economic pressures, pilot shortages and shifting airline priorities. In early 2024, Regional Express (Rex) announced the suspension of its Mount Gambier to Adelaide service, leaving the city without regular commercial air links to the state capital.

According to the South Australian government’s Regional Passenger Rail Review released in late 2023, restoring rail between Mount Gambier and Adelaide could serve an estimated 150,000 annual passengers by 2030, based on population growth trends and commuter demand modeling. The report highlighted the existing freight rail corridor along the Mount Gambier line as a potential foundation for dual-use infrastructure, noting that upgrades would be required to meet passenger safety and accessibility standards.

Local council officials have emphasized that any rail revival would need to integrate with existing bus and active transport networks to maximize accessibility. The City of Mount Gambier’s 2023 Transport Strategy identified rail reconnection as a long-term goal, citing benefits including reduced road congestion, lower greenhouse gas emissions per passenger kilometer, and improved access to education and healthcare services in Adelaide.

Industry analysts note that while freight operations continue on the line, primarily transporting limestone and agricultural products, passenger service restoration would require significant investment in track signaling, platform upgrades, and rolling stock. The Australian Rail Track Corporation (ARTC), which manages the interstate rail network including parts of the Mount Gambier corridor, has not committed to funding passenger upgrades but has indicated openness to feasibility studies under state-led initiatives.

Advocacy groups such as the National Trust for Historic Preservation in Australia and regional rail lobbyists have pointed to successful examples elsewhere, including the reactivation of passenger services on Tasmania’s Melba Line and increased investment in regional rail in Victoria, as evidence that similar projects can be viable with coordinated funding, and planning.

As of April 2026, no formal funding commitment or construction timeline has been announced for a Mount Gambier-Adelaide passenger rail service. However, the city council continues to engage with state transport authorities, and the idea remains included in regional infrastructure discussions under South Australia’s 20-year State Infrastructure Strategy, last updated in 2022.
