Supporters argue that light rail provides the Gold Coast with a permanent, high-capacity public transport spine capable of serving a growing city for decades.

Greater capacity

Light rail can move large numbers of passengers along a relatively narrow transport corridor. This becomes increasingly important as the population grows and road space becomes more constrained.

Previous Queensland Government analysis of the Burleigh Heads to Coolangatta corridor concluded that buses did not present a viable long-term alternative to light rail. Critics of replacing Stage 4 with buses argue that bus capacity would eventually be exceeded, potentially leaving a future government to build light rail anyway.

A continuous north-south network

Extending the tram to Coolangatta would create one continuous light rail corridor linking the northern and southern coastal suburbs.

Passengers would not need to change between buses and trams at Burleigh Heads.

The proposed Stage 4 route would also have connected the light rail directly with Gold Coast Airport.

A long-term investment

Rail infrastructure is expensive to construct but is designed as long-term infrastructure. Supporters argue that the question should therefore not simply be which option is cheaper today, but which transport system will best serve the Gold Coast several decades from now.

Less dependence on cars

The Gold Coast has limited capacity to continually widen roads, particularly through established coastal suburbs.

Light rail supporters argue that a reliable, frequent alternative to driving can move more people without requiring a corresponding increase in road capacity.

Opponents are not necessarily opposed to public transport. Many argue that the issue is whether light rail is the right form of public transport in the right location.

Cost

Light rail is expensive infrastructure.

Stage 3, extending approximately 6.7 km from Broadbeach South to Burleigh Heads, has a reported total investment of approximately $1.55 billion.

Cost escalation was subsequently identified by the Queensland Government as one of the considerations in abandoning Stage 4.

Opponents argue that the money required for another major light rail extension could instead improve public transport across a much wider part of the Gold Coast.

Construction disruption

Building light rail involves substantial construction along the route, including tracks, stations, utilities and changes to roads and intersections.

Residents and businesses along previous stages have experienced years of construction activity.

For communities such as Palm Beach, Tugun and Coolangatta, opponents argue that the disruption and changes to their neighbourhoods would be significant.

Impact on local amenity

Opponents have raised concerns about the effect of light rail infrastructure on the character of southern Gold Coast communities, as well as impacts on businesses, traffic, parking and environmentally or culturally significant areas.

A 2021 Queensland Parliament petition calling for alternative routes and transport modes to be properly evaluated attracted 5,479 signatures.

A fixed route

A tram can only go where the tracks go.

Opponents argue that buses offer considerably more flexibility. Routes can be extended, altered or redirected as population, employment and travel patterns change.

The Queensland Government’s current alternative is not simply to continue existing bus services.

Its proposed GC Surfer would be a metro-style service connecting Robina with Coolangatta via Varsity Lakes, Burleigh Heads and Gold Coast Airport.

The Government says services would run every 10 minutes.

Flexibility

Unlike light rail, buses are not permanently tied to tracks.

Services can potentially branch into residential areas, connect east-west as well as north-south, and change as the city changes.

A broader network

One criticism of light rail is that it concentrates major investment along a single coastal corridor.

Investment in buses could potentially improve public transport for communities away from the coastline as well as those living along the Gold Coast Highway.

Potentially less disruptive

Bus improvements can generally be delivered without the scale of track construction, utility relocation and station construction required for light rail.

That could mean less disruption to businesses, residents and motorists during construction.

The biggest question is whether buses can deliver the capacity, reliability and permanence required as the Gold Coast continues to grow.

Buses can still get caught in traffic

A frequent bus service is only as effective as its ability to move reliably.

If buses operate largely in normal traffic, congestion can affect journey times and reliability. Dedicated bus lanes and priority infrastructure can address this, but they also require road space and investment.

The Government has not yet determined the exact route or infrastructure arrangements for the GC Surfer.

Lower capacity

Individual buses generally carry fewer passengers than light rail vehicles.

As demand increases, maintaining capacity requires more buses and drivers, or larger vehicles and dedicated infrastructure.

Changing modes at Burleigh

Passengers travelling between the southern Gold Coast and destinations further north may need to transfer between bus and tram services.

Transport experts have consequently argued that the design of the Burleigh interchange will be important if the bus alternative is to provide a seamless journey.
