Rail Revival, Bus Cuts and a Busier Airport: What Happened This Week on Sunshine Coast Transport

The Sunshine Coast's transport puzzle got more complicated this week. A Queensland government briefing document released Monday confirmed that Translink's Route 600, the spine service connecting Maroochydore's new CBD precinct on Duporth Avenue to Caloundra's Arthur Street interchange, carried 1.24 million passenger trips in the 12 months to June 2026, up 9 percent on the previous year. That growth figure is now being used by both transport advocates and local councillors to argue the region is outpacing its own infrastructure.

The timing matters. Sunshine Coast Council is scheduled to table a revised transport strategy at its July 17 ordinary meeting, and Sunshine Coast Airport has simultaneously flagged that international seat capacity through its expanded terminal is on track to exceed 400,000 passengers annually by December, a threshold that triggers a new review of ground transport links under Queensland's Airport Surface Access Framework. Put simply, more people are flying in, more are catching buses, and the roads, particularly Nicklin Way between Mooloolaba and Kawana, are absorbing the strain.

The Rail Proposal Gets Fresh Air

The Direct Rail proposal, which would extend the Beerburrum to Nambour Rail Upgrade corridor and eventually connect Maroochydore station to the existing network via a dedicated passenger line, has been circulating in policy documents since at least 2019. This week it got a genuine jolt. Infrastructure Australia published its updated priority project list on Tuesday, and the Sunshine Coast Mass Transit corridor, which encompasses the rail option alongside a bus rapid transit alternative, moved from the "early stage" category into "ready to proceed," meaning it is now eligible for federal co-funding negotiations.

The reclassification does not guarantee a shovel in the ground. Federal Transport Department officials in Canberra have indicated that a business case satisfying a benefit-cost ratio above 1.0 is still required before any Commonwealth money flows. The most recent independent modelling, completed by GHD for the Queensland Department of Transport and Main Roads in March 2026, put the rail option's BCR at 0.94 and the bus rapid transit alternative at 1.18, which gives bus advocates a live argument heading into the council debate later this month.

Sunshine Coast Light Rail Action Group, a community lobby that has pushed the rail-first position for several years, distributed a four-page summary to members on Wednesday pointing out that the GHD modelling used 2023 population projections that predate the Australian Bureau of Statistics' revised coastal growth figures, released in April, which put the Sunshine Coast Statistical Area at 430,000 residents and forecast it crossing 550,000 by 2041. The group argues that updated numbers would shift the BCR calculation in rail's favour.

Bus Passengers Feeling the Pinch

Whatever the long-term solution, the short term belongs to buses, and right now those buses are crowded and, for some routes, less frequent than they were 18 months ago. Translink's March 2026 network review removed a mid-morning service on Route 620, which links Sippy Downs, home to the University of the Sunshine Coast's main Locked Bag campus on Sippy Downs Drive, with Kawana Shoppingworld and the Sunshine Coast University Hospital on Doherty Street, Birtinya. Students and hospital workers flagged the gap almost immediately, and Sunshine Coast Council wrote to Translink in May requesting reinstatement. A Translink spokesperson confirmed this week that the route is "under active review" for the December timetable update.

Airport ground access is a separate but connected problem. Sunshine Coast Airport's international terminal handled its first full year of Singapore Airlines and Air New Zealand services in 2025-26, and car park revenue data published in the airport's June quarterly report showed a 22 percent increase in long-term parking bookings compared with the same period in 2024-25. The Sunbus Route 40 airport shuttle, which departs from Maroochydore's Aerodrome Road interchange, still runs only every 60 minutes, a frequency that airport management acknowledged in its own surface access report is "below benchmarks for comparable regional airports."

Practically speaking, residents and visitors should expect the transport conversation to intensify through July. The council meeting on the 17th is open to the public at the Sunshine Coast Council Chambers on Ochre Street, Maroochydore, and written submissions on the transport strategy are being accepted until July 10. For anyone relying on the 620 route between Sippy Downs and Birtinya, the safest approach is to check the Translink app before travel, the timetable gap around 10am remains unresolved for now.
