The aboriginal Nauo Tribe were the first people in the area. In the early days the area was known as Shannon and the first white settlers came to the district in 1904. The township was surveyed in 1908 and was first called Bellwood, but the name of the towns railway siding called Yeelanna stuck. Yeelanna had a policeman in the early days who lived in a tent, and there were two brick cells there for the wrong-doers. A large dam was dug in 1909 and supplied the township in the early days, and later was connected to the Yeelanna oval to water it for football and cricket. Yeelanna had a butcher shop, a blacksmith shop and a 19-room hotel in the early days. The hotel opened in 1912 and closed in 1924, it was then dismantled and the stone was transported to Kimba to build the current Kimba Gateway Hotel. Also, there was a bank, a bakery until the 1950s, a boarding house that opened in 1910 and a primary school that opened in 1908 and closed in 1972. The school is now the Bellwood Museum. There was a railway station, five railway cottages that were demolished in the mid to late 1970s, and a couple of mechanical businesses. The town had two shops in the early 1980s, with one being also a post office. The last shop closed was the Yeelanna General Store in the late 1980s. There were five fuel agents in town, with at least two still being their in the 1990s. There is still one mechanical business. The old oval owned by the Yeelanna Memorial Association is used to put in a crop by the Yeelanna Memorial Association to help with their funds. The Recrerational Park with the new oval was created in the 1950s and the new oval was used until around 2003–04 when the new oval was last used by the Karkoo/Yeelanna cricket club. The part of the recreation ground where the new oval was, has been sold and a new house and shed built on it where a spraying and windrowing business is run from, but the part of the recreation ground where the toilets, tennis and netball courts are remain in public ownership. The town has a Hall with public toilets, a post office in one of the front rooms of the Yeelanna Hall, grain silos that were built in the 1960s and a railway line that has been their since around 1908 and transported grain to Port Lincoln for export until 2018 when all grain transportation on Eyre Peninsula went by Road Train, fourteen houses, a Uniting Church, a CFS brigade, an Agriculture Bureau that has existed since 1908 that is the Yeelanna/Karkoo Ag Bureau that has their meetings at the Kooplex at Karkoo, a Country Woman's Association, a museum called Bellwood Museum, and a historic cemetery.

Yeelanna Football club was formed in 1909 and the Netball club in about 1934 and amalgamated with the United football and netball clubs in 1964 to form the United Yeelanna Football and Netball clubs. The amalgamated club kept using the blue and gold Yeelanna colours. Yeelanna football and netball clubs played at three home ground's being Murdinga, Karkoo and Yeelanna. They stopped playing at Murdinga in 1974 and Yeelanna at the end of the 1994 season.
