From next Tuesday, a new early morning train will run between Varsity Lakes and Brisbane Airport, adding an extra 2250 seats weekly between the two centres and helping ease congestion on peak-hour services.

It follows a major review of public transport and is the first stage of a package that includes a revamp of bus services, particularly across the southern Gold Coast.

The new $11 million, six-carriage train will leave Varsity Lakes at 4.34am each day from next Tuesday and arrive in Brisbane before 6am and Brisbane Airport before 6.30am.

From late June, connecting bus services will run from Gold Coast Airport at Coolangatta to Varsity Lakes, meaning, for the first time, passengers can travel from the NSW border to Brisbane city and the airport, with just one change.

As well, there will be extra feeder buses for key hubs, more services on the western side of the rail line to meet the needs of schoolchildren, and new routes into expanding residential areas.

The report found $4.54 billion of developments identified in the region — which takes in Robina, Varsity Lakes, Burleigh Heads, Burleigh Waters, Burleigh West, Elanora, Reedy Creek, Palm Beach and Tallebudgera — were under construction, with the remaining $2.561 billion in the planning stages.

Despite the significant activity, the research, compiled by Colliers’ research manager Lynda Campbell, found the total dollar value of development had dipped slightly from the $7.338 billion recorded last year, but was still up substantially on the $6.214 billion identified in 2007.

Spending on infrastructure, which continues to account for the largest slice of development in the region, had also marginally decreased from the $3 billion reported 12 months ago, with about $2.75 billion of projects either in progress or on the drawing board.

The total value of apartment and retirement projects also dropped, from $816 million to $738 million and $195 million to $170 million respectively.

On the other hand, spending on housing development increased from $1.47 billion to $1.51 billion, mixed-use projects from $1.18 billion to $1.26 billion and commercial development from $415 million to $671 million.

Colliers’ Gold Coast director in charge Stewart Gilchrist said the majority of construction in the region was concentrated in the fast-growing suburbs of Robina and Varsity Lakes.

“These suburbs are at the geographical heart of the Gold Coast, but they have become much more than that, staking a claim as one of the city’s prime centres for business and entertainment, and a sought-after residential address,” he said.

“Major road and rail improvements will support this position, making the area even more accessible.”

Several major infrastructure projects in progress include an $8.3 million upgrade to Christine Avenue, the first phase of a $920 million rail extension from Robina to Coolangatta, $287.7 million expansion of Robina Hospital and the $6 million Robina Police Station.

There are also major infrastructure improvements in the pipeline, including a $75 million upgrade to Burleigh Connection Road, $22.6 million expansion to Robina Library, a new $9.7 million Australian Technical College, and upgrades to the motorway and interchanges from Nerang to Varsity Lakes.

Ms Campbell said the $1 billion Varsity Lakes, the $500 million The Glades in Robina and the $440 million The Observatory at Reedy Creek were the largest residential projects in the region.

“Many of the big tracts of land have now been developed, so we are seeing plans being put forward for smaller residential projects, with an end value of about $30 million to $40 million,” she said.

“There is also a number of smaller apartment projects either started or in the planning stages, particularly in Palm Beach where older properties are increasingly making way for this style of development.”

Ms Campbell said mixed-use and commercial developments were also a major focus in the area, spearheaded by projects like the $1 billion Varsity Lakes and the $300 million Robina Town Centre shopping centre expansion.

“Robina and Varsity Lakes have been carefully masterplanned and, as such, both mixed-use and commercial development has been integrated into the design of the area to create a place where people can live, work and be entertained all from the one postcode,” said Ms Campbell.
