Kwong Sue Duk, also known as Kwong See Tek, () (4 September 1853 – 17 February 1929) was a Chinese Australian herbalist, merchant, and miner. Early life Kwong Sue Duk was born in Guangdong Province, China, in 1853. In his teens, he travelled to the Californian gold rush where he made a modest fortune mining for gold. He returned home to Toishan, China, and embarked on an education in Traditional Chinese medicine. Immigration to Australia In 1874, Kwong Sue Duk married his first of four wives, Gee An Gow. In 1875, after the birth of his first son, Kwong Kong Sing, Kwong settled in Cooktown, Queensland, Australia, gateway to the Far North Queensland gold rushes. Career In 1882, Kwong returned from China to settle in Southport, Northern Territory. Operating under his business name, Sun Mow Loong, he eventually established a successful general trade store and real estate enterprise. He was well respected and influential amongst the Chinese and European communities and was consulted over many matters concerning the Chinese. In 1884, Kwong Sue Duk married his second of four wives, Chun Ngor Gwei, and obtained his naturalisation certificate in Australia. In 1885, Kwong Sue Duk moved to Palmerston (early Darwin) and in March 1887 he met and married his third of four wives, Yuen Yuk Lau. In 1888, he built the famous Sue Wah Chin Building, originally known as Stone House. In 1889 he returned to China and brought out his first wife and three children to Palmerston. In 1897, a tropical cyclone damaged much of Palmerston, including Kwong's group of rental properties. His first wife had difficulty adjusting to the harsh conditions, and in 1898 he travelled with her to China where she chose to remain with her four children. In 1899, Kwong met and married his fourth wife, Wong Kwei Far, and returned with her to Palmerston. However, the damage of the cyclone and the generally depressed state of the Northern Territory economy left Kwong in a poor financial situation. He became a citizen in 1889. In 1902 the family set up a store and business in Cairns, Queensland where he sold mostly Chinese goods. In the back of the store he had an office where he dispensed Chinese herbal remedies. In 1910 he returned from Hong Kong to settle in Townsville, Queensland, and in 1913 most of the family followed. Kwong established another successful Chinese herbal medicine
