IndexSummaryBackground on the EWB ChallengeSelected Challenge ProjectCommunity ContextIdentification of StakeholdersIdentified Problem StatementReferencesSummaryThe following report focuses on the issue of transportation and access to services for the local community in the remote area of Cape York in northern Queensland, Australia. Due to the effects of heavy rainfall, some areas within the region become inhabitable and inaccessible, and current roads also pose the problem of being run off by rainwater, contributing to sedimentation in rivers and encouraging the spread of weed seeds , as they are mostly built of earth or gravel. The project brief aims to identify a solution with sustainable road construction, and the roads built must not have negative effects on the environment, thus addressing the problem of sedimentation and the spread of weeds.

In 2007, EWB launched its design challenge for first-year engineering students [1]. EWB provided students with a design challenge with areas for students to focus on, along with all the underlying data to help them better prepare a design element to address the problem [1]. In 2018, EWB undertook a water and sanitation project in Cambodia and developed a solar-powered water system for Ratanakiri village [2]. Selected Challenge Project This year the EWB Challenge is focusing its efforts on Cape York in Queensland, Australia, and will address the development of sustainable roads in Design Area 1: Transport and Access: Road Design to Reduce Environmental Impact [3]. Community Context Cape York is a remote peninsula in northern Queensland, Australia, with predominantly flat tropical landscapes. The region is significantly eroded due to a lack of tectonic activity and is subjugated by meandering rivers and immense floodplains [4]. There are heavy rains between November and April, a period during which it becomes almost uninhabitable, and a dry season between May and October [3] [5]. Due to heavy rain, some areas are only accessible by four-wheel drive vehicles and light aircraft. The roads are mostly dirt and gravel, however the Peninsula Development Road (PDR) is slowly being bituminised with the help of the government [3]. During the rainy season, pavement makes communities inaccessible to vehicles, so an alternative was established that served those affected by airstrips carrying basic necessities, food and transportation to people. The heavy rain also caused the dirt road to loosen and wash away, taking with it weed seeds that are then deposited into river systems as the gravel settles. This poses a problem for the traditional owners of the land, to whom the Country was returned following the Aboriginal Land Act 1991 and the Cape York Peninsula Heritage Act 2007 [6]. Years of cattle ranching have altered the ecosystem and biodiversity, and land management activities revolve around the rainy and fire seasons as rangers prioritize responding to fires and floods over planning infrastructure projects.
