South-east Queensland is one of Australia‘s fastest-growing regions, with Brisbane, the Sunshine Coast and the broader south-east Queensland corridor experiencing rapid population growth, significant economic expansion and increasing pressure on existing transport infrastructure. High speed rail connecting Brisbane and the Sunshine Coast, as part of the broader east coast network, has the potential to transform mobility, support sustainable growth and reshape the region’s economic geography for generations to come.
South-East Queensland: A Region on the Move
South-east Queensland encompasses one of Australia‘s most dynamic and rapidly expanding urban regions. The area stretching from the Gold Coast in the south through Brisbane to the Sunshine Coast in the north is home to more than four million people, a figure projected to grow substantially over coming decades as interstate and international migration continues to drive population increases.
This growth brings with it significant transport challenges. Road congestion on the Bruce Highway and other major corridors between Brisbane and the Sunshine Coast is already severe during peak periods, and existing rail services, while valuable, do not offer the speed or capacity needed to meet the region’s long-term transport demands.
Brisbane: Australia‘s New World City
Brisbane is Australia‘s third-largest city and one of its most rapidly growing. As the capital of Queensland and the economic heart of south-east Queensland, Brisbane is a major centre for business, education, tourism, health and government services. The city is undergoing a period of significant transformation, driven by:
- Strong population growth and urban development
- Major infrastructure investment including Cross River Rail and the Brisbane Metro
- The upcoming Brisbane 2032 Olympic and Paralympic Games
- Growth in knowledge industries, technology, health and education sectors
- Increasing international connectivity and profile
Brisbane’s role as the anchor city at the northern end of the east coast high speed rail corridor makes it a critical node in any future network. High speed rail connections from Brisbane to Sydney, Melbourne and intermediate cities would strengthen the city’s economic relationships with the rest of Australia and support its ambitions as a globally competitive city.
The Sunshine Coast: Queensland’s Growth Region
The Sunshine Coast, located approximately 100 kilometres north of Brisbane’s central business district, is one of Australia‘s fastest-growing regional cities. With a population approaching 400,000 and projected to grow significantly in coming decades, the Sunshine Coast is evolving from a tourism and lifestyle destination into a diversified regional economy with strengths in:
- Health and medical services, anchored by the Sunshine Coast University Hospital
- Education, including the University of the Sunshine Coast
- Technology and innovation, with a growing digital and creative industries sector
- Tourism, hospitality and events
- Construction and property development
- Retail, professional services and small business
The Sunshine Coast’s growth has been accompanied by increasing demand for improved transport connections with Brisbane and beyond. The existing rail network does not directly serve the Sunshine Coast’s main urban centres, and road congestion on the Bruce Highway is a persistent challenge for residents, businesses and visitors.
The Case for High Speed Rail Between Brisbane and the Sunshine Coast
High speed rail connecting Brisbane and the Sunshine Coast would deliver transformative benefits for both communities and for the broader south-east Queensland region:
Dramatically Reduced Travel Times
A high speed rail connection between Brisbane and the Sunshine Coast could reduce travel times to as little as 20 to 30 minutes, compared to around 90 minutes to two hours by road during peak periods. This would make the Sunshine Coast genuinely accessible as a commuter destination from Brisbane and open up new possibilities for residents, workers and businesses in both locations.
Economic Development and Diversification
Fast rail connectivity would strengthen the Sunshine Coast’s economic base by:
- Expanding access to Brisbane’s large and diverse labour market for Sunshine Coast residents
- Making the Sunshine Coast more attractive to businesses seeking lower-cost locations with strong connectivity
- Supporting growth in knowledge industries, health, education and technology sectors
- Boosting tourism by making the Sunshine Coast more accessible from Brisbane, Sydney and beyond
- Attracting investment in commercial and residential development around station precincts
Relief for Existing Transport Infrastructure
High speed rail would provide significant relief for the Bruce Highway and other road corridors between Brisbane and the Sunshine Coast, reducing congestion, improving road safety and lowering the cost of road maintenance and expansion. It would also complement and extend the reach of Brisbane’s metropolitan rail network.
Support for Sustainable Growth
By providing a high-capacity, low-emission transport alternative, high speed rail would support the Sunshine Coast’s ambitions for sustainable growth, helping to manage the environmental impacts of population increase while maintaining the region’s liveability and natural assets.
Brisbane 2032 and the High Speed Rail Opportunity
The Brisbane 2032 Olympic and Paralympic Games represent a unique opportunity to accelerate transport infrastructure investment in south-east Queensland. Major international events have historically acted as catalysts for infrastructure development, and the 2032 Games provide a clear deadline and international spotlight that can help to drive planning and investment decisions.
While delivering a full high speed rail connection between Brisbane and the Sunshine Coast by 2032 would be extremely challenging given current planning timelines, the Games provide an important context for accelerating corridor planning, protecting land and making early investment decisions that position the region for high speed rail in the years following the event.
Integration with the Broader East Coast Network
A Brisbane–Sunshine Coast high speed rail connection would not exist in isolation. As part of the broader east coast high speed rail vision, it would form the northern anchor of a network extending south through Brisbane to Sydney, Canberra and Melbourne.
This integration means that Sunshine Coast residents and businesses would ultimately have access not only to fast connections with Brisbane but also to the full east coast network, with high speed rail journeys to Sydney, Canberra and Melbourne becoming practical alternatives to flying for many travellers.
Station Locations and Urban Development
The location of high speed rail stations in Brisbane and on the Sunshine Coast will be critical to maximising the network’s benefits. Key considerations include:
Brisbane Station Options
- Integration with Brisbane’s existing rail network at Central Station or other major interchange points
- Connections to Cross River Rail and the Brisbane Metro for seamless onward travel
- Access to Brisbane Airport as a potential intermediate stop or connection point
- Proximity to major employment, education and activity centres
Sunshine Coast Station Options
- Maroochydore, as the Sunshine Coast’s emerging city centre and commercial hub
- Nambour or other established centres with existing transport connections
- Sunshine Coast Airport, supporting aviation connectivity and tourism access
- University of the Sunshine Coast precinct, supporting education and health sector growth
Station precincts have the potential to become significant centres of economic activity in their own right, attracting commercial development, housing, retail and services that benefit from high speed rail accessibility.
Environmental Considerations
Planning a high speed rail corridor through south-east Queensland requires careful consideration of the region’s significant environmental assets, including:
- Coastal wetlands, waterways and marine environments
- Hinterland forests, national parks and biodiversity corridors
- Agricultural land and rural landscapes
- Existing urban development and future growth areas
Environmental impact assessment and route selection will need to balance the need for direct, high-speed alignments with the protection of the region’s natural values and the minimisation of impacts on existing communities.
Community and Stakeholder Engagement
Delivering high speed rail in south-east Queensland will require broad community and stakeholder support. Key voices in the planning process include:
- Sunshine Coast Council and Brisbane City Council
- The Queensland Government and its transport and planning agencies
- Business chambers and economic development organisations across the region
- Community groups, residents and landowners along potential corridors
- Environmental organisations and regulators
- Tourism, education and health sector stakeholders
Genuine engagement with these groups will be essential to developing plans that reflect community values, address legitimate concerns and build the broad support needed to sustain a long-term infrastructure programme.
The Path Forward for South-East Queensland
South-east Queensland’s rapid growth, combined with the transformative potential of high speed rail, creates a compelling case for prioritising the Brisbane–Sunshine Coast corridor within the national high speed rail programme. The region’s population trajectory, economic dynamism and transport challenges all point to the need for bold infrastructure investment that can support sustainable growth over the coming decades.
With the High Speed Rail Authority progressing corridor studies and the Queensland Government investing heavily in transport infrastructure ahead of the 2032 Games, the conditions are more favourable than at any previous time for advancing high speed rail planning in south-east Queensland.
For Brisbane, the Sunshine Coast and the communities between them, high speed rail represents not just a faster way to travel, but a fundamental opportunity to shape the region’s future, strengthen its economy and improve the quality of life for millions of Australians.
