About Upper Main Arm
Upper Main Arm is a small rural locality in the Byron Shire, tucked into the lush hinterland of northern New South Wales approximately 10 kilometres west of Mullumbimby and around 30 kilometres from Byron Bay. The locality covers 16.8 square kilometres of fertile valley country, with properties running along Main Arm Road through rolling paddocks and subtropical vegetation. With a 2021 population of 283, it is a tight-knit rural community with a below-average median income reflecting its alternative-lifestyle demographic.
Upper Main Arm is home to the historic Kohinur Hall, a community gathering point that hosts local events and reflects the locality's strong sense of community identity. Main Arm Upper Public School serves local families, and the surrounding landscape of creek frontage, rainforest pockets, and farmland draws those seeking an off-the-beaten-track Byron hinterland lifestyle. The area appeals strongly to small-scale farmers, artists, and those drawn to alternative living, sharing postcode 2482 with Mullumbimby, the nearest service town.
Upper Main Arm falls under postcode 2482 and is governed by the local council Council (LGA). For state elections, residents vote in the Lismore electorate.
