David Siang Hai Teoh is a prominent Australian businessman best known for founding TPG Telecom and Tuas Limited. Despite his immense influence in the telecommunications sector, Teoh remains a highly private individual, rarely seen in public or giving interviews. His journey from Malaysia to Australia and his rise to one of Australia’s wealthiest individuals is a testament to his entrepreneurial spirit and strategic acumen.

Early Life and Migration to Australia

David Siang Hai Teoh was born on January 1, 1956, in Malaysia. Although detailed information about his early years is scarce, it is known that he emigrated to Australia in 1986 with his wife, Vicky Teoh. Seeking better opportunities, the couple settled in Sydney, where they would eventually build one of Australia’s most successful telecommunications companies.

Founding of TPG Telecom

In 1992, David and Vicky Teoh founded Total Peripherals Group (TPG), which initially operated as a computer retail business. Over time, TPG pivoted into telecommunications, driven by Teoh’s vision to capitalize on the burgeoning internet market. The company’s growth was propelled by strategic acquisitions, including:

• Mobile Spectrum Licenses
• Internet Service Providers (ISPs)
• Corporate Telecommunication Services

These acquisitions enabled TPG to evolve into one of Australia’s leading internet service providers, offering both fixed-line and mobile services.

Merger with Vodafone Hutchinson Australia

One of the most significant milestones in Teoh’s career was the proposed merger between TPG and Vodafone Hutchinson Australia. In August 2018, Teoh announced discussions for a $13 billion merger aimed at creating a formidable player in the Australian telecommunications market. The merger was initially blocked by the Australian Competition & Consumer Commission (ACCC), which argued it would reduce consumer choice.

However, in early 2020, the Federal Court overturned the ACCC’s decision, allowing the $15 billion merger to proceed. This merger solidified Teoh’s position as a key figure in the industry and created a stronger competitor to Australia’s dominant telecom players, Telstra and Optus.

Establishment of Tuas Limited and Expansion into Singapore

In addition to his success in Australia, David Teoh expanded his business ventures to Singapore. He founded Tuas Limited, which owns Simba Telecom, a telecommunications provider in Singapore. Simba Telecom has focused on offering competitive mobile plans to disrupt the established market in Singapore, much like TPG did in Australia.
