both the segments. Medals The medals for the Games were officially unveiled at a charity gala held on 4 November 2017. Australian Indigenous artist Delvene Cockatoo-Collins designed the medals, while they were produced by the Royal Australian Mint. The design of the medals was inspired by the coastline of Gold Coast along with Indigenous culture. Furthermore, Cockatoo-Collins mentioned, "the medal design represents soft sand lines which shift with every tide and wave, also symbolic of athletic achievement, The continual change of tide represents the evolution in athletes who are making their mark, Records are made and special moments of elation are celebrated". Approximately 1,500 medals were created to be distributed to the medalists and each measures approximately 63 millimetres in diameter. The medals weigh between 138 and 163 grams. Volunteering Over 15,000 volunteers were hired for the Games. Over 45,000 applicants applied to become a volunteer. The uniforms for the volunteers were revealed on 11 November 2017 at the Gold Coast Convention and Exhibition Centre. Former Gold Coast Titans player Mat Rogers who was present at the uniform showcase ceremony, said that the uniforms were "very Gold Coast" and it was like an "active wear". Hard Yakka was the official supplier of the uniforms for the volunteers. Transport During the Games period, free public transportation within Queensland region was provided to ticket and accreditation holders. The free transportation services were available on local buses, train and Gold Coast light rail (G:link) services on the Gold Coast and on TransLink and Qconnect bus services in Cairns and Townsville. The Gold Coast light rail system, connected a number of the key games venues including the Optus Aquatic Centre, Broadwater Parklands and the Gold Coast Convention & Exhibition Centre with the major accommodation centres of Surfers Paradise and Broadbeach and the Athletes Village at Parklands. An extension to the system was announced in October 2015, connecting the then current terminus at Gold Coast University Hospital to the railway line to Brisbane at Helensvale. The extension opened in December 2017, in time for the games. Four temporary Games lanes were introduced along the M1 and activated at different times to decrease traffic disruptions for road users. These were used by police and emergency vehicles, spectator shuttle buses and accredited Games family and athletes. The Gold Coast Airport served as the official airport for the Games.
