Oxley Museum is managed by members of the Wellington Historical Society who work on a volunteer basis.
The collection reflects the European settlement of Wellington and its district and features a Chinese room, a Military room, Trades and Commercial room, Medical room and a room with a display of costumes. Several rooms on the ground floor have been set up as a Victorian House – bedroom, kitchen, pantry and laundry.
In the grounds of the museum, the visitor can see a one room school house which was removed from Windora and reconstructed, and a slab cottage once occupied by the Stinson family on a property outside Wellington and subsequently removed and re-erected on its present site.
There are also two sheds with farm machinery, horse drawn vehicles and large items (printing press etc). A feature item on display is the Centenary of Federation Signature Quilt with over 700 signatures of Wellington residents which was completed in 2002.
The Oxley Museum has a large number of books and pamphlets available for sale that cover the history of Wellington and adjacent areas.
