Maha Sinnathamby AM (born 10 December 1939) is a prominent Australian entrepreneur and property developer. He is the visionary behind the Greater Springfield project, which stands as Australia's largest master-planned community.

In recognition of his innovative leadership in creating Springfield—the nation's first privately developed city—Sinnathamby's Springfield City Group was honored in 2019 with induction into the Queensland Business Leaders Hall of Fame. This accolade highlights the development's significance as a landmark nation-building initiative.

Early life and education

Maha Sinnathamby was born on 10 December 1939 in Malaysia. Of Sri Lankan Tamil heritage and practicing Hinduism, he grew up on a British-operated rubber plantation located in Rantau, Negeri Sembilan. His father worked on this estate and endured captivity as a prisoner of war during the Japanese occupation of Malaysia, being liberated in 1945.

Sinnathamby relocated to Australia to pursue civil engineering studies at the University of New South Wales. After completing his degree, he gained professional experience as a civil and design engineer throughout Southeast Asia before returning to Australia.

Business career

Beginning his property ventures in Perth in 1971, Sinnathamby later moved to Queensland during the early 1980s. There, he broadened his portfolio by developing residential subdivisions alongside commercial real estate projects.

Greater Springfield Development

In 1992, Sinnathamby partnered with Bob Sharpless to purchase a 2,860-hectare site near Ipswich, located southwest of Brisbane, for $7.9 million. He played a pivotal role in advocating for critical education and transportation infrastructure, culminating in rezoning approval granted by the Queensland Parliament in 1997.

Recognized as Australia's largest master-planned community—and ranking tenth worldwide—Greater Springfield is structured around three key sectors: health, education, and information technology:

• Education City: This educational precinct at Springfield Central encompasses a campus of the University of Southern Queensland, ten schools, student accommodation, and a technical college, collectively serving approximately 14,000 students.
• Health City: Occupying 52 hectares, this health-focused area includes the Mater Private Hospital. Additionally, the Aveo Group is developing 2,500 senior living residences integrated with healthcare services.
• Idea City: Serving as the IT hub, it houses Australia's Polaris Data Centre and fosters innovation commercialization through collaborations between government entities and private enterprises.

Public and private investments have surpassed $15 billion. The establishment of a $1.2 billion dual-track railway and transit hub in 2013 enhanced connectivity between Greater Springfield and the broader South East Queensland region. The community currently hosts around 35,000 residents, with projections estimating growth to 105,000 by 2030. The master plan dedicates nearly 30% of land area to preserved green spaces.

Springfield City Group

Following acquisition of the original landholding, Sinnathamby established Springfield City Group (previously known as Springfield Land Corporation), where he serves as chairman. This entity oversees all aspects of Greater Springfield's ongoing development.

Personal life

He wed Yoga in 1968, and together they have four children: three daughters named Raynuha, Meera, and Uma, along with a son, Naren. Sinnathamby is an avid golfer who frequents the Brookwater course.

Net worth

Sinnathamby first appeared on the Financial Review Rich List in 2017, with an estimated net worth of AUD 1.02 billion. By 2025, his fortune had nearly doubled, reaching AUD 2.01 billion.
