Bandar Sunway, officially known as Sunway City, is a prominent integrated township in Subang Jaya, Selangor, Malaysia. Its remarkable transformation began in 1986 from a desolate tin mining wasteland into a vibrant urban center [2, 13]. This meticulously planned development is approximately 800 acres (323 hectares) and is located merely 20 minutes from Malaysia’s capital city, Kuala Lumpur [1]. The township embodies a unique "Resort Living Within A City" concept, offering a wide spectrum of amenities and services within a single vicinity [2].

Today, Bandar Sunway stands as a testament to human ingenuity and urban foresight. It is a self-contained integrated resort city featuring residential areas, commercial centers, educational institutions, a medical facility, theme parks, hotels, and a major shopping mall [2]. The city attracts an impressive annual visitation of 30 million people, solidifying its status as one of the region's most preferred tourist destinations and a highly sought-after place to live, work, study, play, and shop [2].

• Bandar Sunway was transformed from a former tin mining wasteland starting in 1986 [1, 13].
• The township spans approximately 800 acres (323 hectares) [1].
• As of 2020, the population of Sunway (Bandar Sunway) was 72,162 [3].
• It is home to Malaysia's first themed shopping mall, Sunway Pyramid, which opened in 1997 [2, 13].
• Sunway Lagoon, a multi-park destination covering 88 acres with over 90 attractions, is a key draw [2, 13].
• The Sunway Integrated Resort City attracts an annual visitation of 30 million [2].
• Bandar Sunway is Malaysia's first fully integrated Green Township, as certified by the Green Building Index [13].
• The township operates Malaysia's first elevated electric bus system, the BRT-Sunway Line, a public-private partnership [13].
• Sunway Medical Centre, established in 1999, is an accredited private hospital offering comprehensive healthcare services [13].

Bandar Sunway falls under the administrative purview of both the Subang Jaya City Council (MBSJ) for the majority of the township and partially the Petaling Jaya City Council (MBPJ), with the MBSJ taking over most administration from MBPJ since 1997 [2, 4]. The township is divided into neighborhood sections from PJS 7 to PJS 11, with MBPJ retaining administration over northern parts including PJS 10, PJS 5, PJS 6, Sunway Mentari, and Setia Jaya [2].

On the broader political landscape, Bandar Sunway is part of the Subang constituency at the federal parliamentary level, and the Subang Jaya constituency at the state legislative assembly level in Selangor [4]. Local governments in Malaysia, unlike federal and state governments, are appointed by the state government rather than being elected, a practice that has been in place since 1965 [5].

The economy of Bandar Sunway is primarily driven by the Sunway Group, a major Malaysian conglomerate with diverse interests [15]. Their core businesses, including real estate, construction, education, healthcare, retail, and hospitality, are integral to the township's economic fabric [15]. The Sunway Group operates on a unique "Build-Own-Operate" business model, becoming a part of the communities they serve and striving to create sustainable developments where people can live, learn, work, play, and stay in a healthy and connected environment [14, 15].

This integrated approach has transformed Bandar Sunway into a significant economic driver, attracting more than 42 million visits annually and supporting a vibrant community [14]. The consistent development and expansion of world-class facilities, such as the Sunway Pyramid shopping mall, Sunway Lagoon theme park, and Sunway Medical Centre, contribute significantly to the local economy through tourism, retail, education, and healthcare sectors [2, 13].

Bandar Sunway is well-connected through an extensive network of highways, providing accessible links to major cities such as Kuala Lumpur, Shah Alam, Petaling Jaya, and Klang. Key highways include the Federal Highway, Shah Alam Expressway (KESAS), New Pantai Expressway (NPE), and Damansara–Puchong Expressway (LDP) [2]. The township is also served by efficient public transportation, notably Malaysia's first and currently only elevated Bus Rapid Transit (BRT) line, the Sunway Line [2]. This BRT system enhances connectivity by linking major points within the township, including Sunway Mentari, Sunway Pyramid, and Monash University, and connecting to the Setia Jaya KTM Station and the LRT Kelana Jaya Line Extension Station in USJ 6 [2, 13].

Historically, Bandar Sunway even had its own monorail service, the Sunway Monorail, from 2000 to 2007, which was later incorporated into the BRT line [2]. Additionally, rapidKL bus services and the Smart Selangor bus route SJ02 further contribute to public transport accessibility [2]. The township also benefits from its proximity to Subang Airport, with rail connections available via the Subang Jaya station [2]. A first-of-its-kind water treatment plant in Sunway South Quay produces approximately 10,000m³ of water daily for commercial buildings, reducing reliance on public water supply [14].
