The first recorded European exploration of the area around Tomerong probably occurred when Lieutenant James Grant of the Lady Nelson ventured inland from Jervis Bay up to 13 kilometres in 1801. Land grants occurred around Jervis Bay and St Georges Basin in the 1830s and 1840s with the first Tomerong land sale occurring at Nowra on 8 May 1855. Settlement increased as the a bridge was constructed across Falls Creek and the development of the main south coast road provided transport and mail services. The Travellers Rest Hotel was opened in 1857 to service the travelling public and, five years later, a Post Office and School were established. Both celebrated their 150th anniversary in 2012. A Church was constructed in 1877 and a General Store commenced operation about 1882, but it was the development of the timber industry that saw Tomerong's importance grow, just as farming had started to wane. For the next 100 years the industry was so important to the village that it resulted in the headquarters of the Clyde Shire being constructed in 1908. A School of Arts was constructed in 1926 and remains a popular venue for entertainment, not only for the locals. The consolidation of sawmills saw local enterprises reduce in the 1960s and 1970s and the bypassing of the village in 1995 by the Princes Highway meant the village became more attractive for family living adjacent to the growth areas of St Georges Basin and Huskisson/Vincentia.
Contemporary Tomerong
Since the last sawmill closed in the mid 1980s and the main south coast road bypassed in 1995, the village, whilst quieter, has increased in population and dwellings. Its precinct is still dominated by the , , Post Office, Church and the volunteer building. The has a busy patronage with private and community events. A new Rural Fire Service building was opened in 1991 opposite the Union Church that, whilst undergoing major repairs in 2000s, has seen little use since 1993. The Public School was the subject of a major building program in 1995 and remains the major employer in the village. Volunteer organisations are an important part of village life with members active in P&C, Rural Fire Service, the and the School of Arts. Other bodies have been organised as required; such as the , that organised the Church's restoration; the Campaign, that successfully lobbied to prevent a local shale quarry from being used as a non-putrescible waste dump; and the Sesquicentenary Committee organising celebrations for the primary school's .
Geography and climate
The village is 48 metres above sea level and is overlooked to the north by Tomerong Hill at 111 metres. The settlement is concentrated on a north to south spur of this hill which runs two kilometres down to Tomerong Creek 20 metres above sea level. A ridgeline, of about 100 metres above sea level, located two kilometres west of the village runs generally north to south. Creeks north east of the village generally drain to Currambene Creek and Jervis Bay, whilst those to the south generally run to St Georges Basin. The village lies near the southern extremity of the Sydney Basin with the higher areas to the north and west comprising Nowra Sandstone that thins to the south and east to reveal Wandrawandian Siltstone. Average minimum and maximum temperatures in degrees celsius and average rainfall in millimetres are shown in the following table.
