The town of Nhill is located between the smaller centres of Dimboola and Kaniva in the west of the state. It is approximately at the half-way point between Melbourne and Adelaide on the Western Highway.
Nhill is situated within a rich wheat growing and sheep grazing district, as well as being surrounded by a number of state and national parks. The Little Desert National is just a short drive south of town while the vast waters of Lake Hindmarsh are around 40 kilometres north-east of Nhill near the town of Jeparit.
The commercial centre of Nhill extends along Nelson Street and around the corner into Victoria Street, both of which are wide boulevards with gardens located within their median strip. Goldsworthy Park has particularly attractive gardens and occupies the central strip along the northern end of Victoria Street. It features a large war memorial, a bronze draught horse monument to signify the important role the breed had in working the wheat fields, a band rotunda, visitor information centre, playground, shelters and lawns. A number of historic buildings line both Nelson and Victoria Streets including the post office (built in 1888) and several large hotels.
A large grain silo, which is apparently Australia's largest single-bin silo, can be found at along Davis Avenue near the railway line. It is part of the historic Noske Flour Mills.
At the southern end of town is Lake Nhill and adjoining swamplands, although they can dry out in periods of drought. When there's water about, the lake is ideal for boating with a boat ramp located within the picnic grounds at the southern end of Campbell Street. The Nhill Swamp Boardwalk is an extensive elevated walkway which winds its way through the swampland on the western side of the lake. A branch of the walkway extends out to a bird hide from which birds and other animals can be observed.
Jaypex Park is situated along the eastern side of Victoria Street and also provides access to Lake Nhill via the Nhill Swamp Boardwalk. Within the park there's an extensive playground, picnic shelters, BBQ facilities and an information shelter containing a preserved sample of an Aboriginal scar tree. Also found in the park is the John Shaw Neilson Memorial Cottage, which was transported to its present site from Penola in South Australia where the lyric poet was born in 1872. It contains documents and relics related to the poet's life.
