Blyth, SA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Blyth is a small farming town in South Australia's Mid North, about 132 kilometres north of Adelaide and just west of the Clare Valley, in the Wakefield Regional Council. The surrounding Hundred of Blyth was proclaimed in 1860 and named after Sir Arthur Blyth, three times Premier of South Australia, and the township itself was laid out in 1875 with the railway running through its centre. The district's climate and soils suit wheat, barley, hay and the grazing of sheep and cattle, and farming still shapes local life. In town, the old Masonic hall has been reborn as the Blyth Cinema, while the Dean Nicolle Eucalypt Walk, opened in 2025 along the former railway corridor, gathers thousands of plants, including hundreds of rare eucalypt varieties.
