The Toowoomba and District Old Machinery Society Inc. was formed in 1996 by a group of local enthusiasts who discovered the need for a club of likeminded people interested in old machinery and memorabilia.

The aim of the Society is to preserve and promote the interest of old machinery within the community.  The Society started with 6 members and saw a rapid growth within 4 years to over 80 members.  Today the Society is one of the largest of its type in Queensland with over 90 members, many of whom are actively involved in club and community events.

The Society is a family based group and has the ability to help members operate their equipment efficiently and safely.  We can assist members in dating most types of equipment.  We welcome junior members and are only too happy in assisting them and helping them explore the ways of their forefathers.

The Society has achieved a well recognized reputation within the community; for example several members are actively involved with the Jondaryan Woolshed.  We have members from throughout Queensland and we assist many other societies in providing both static and working displays for their events including rallies, local shows, fetes, fundraising events and field days.

As a member society of the National Historic Machinery Association (NHMA), TADOMS provides members with appropriate insurance cover for operating vintage machinery within the community.

From 2026, we will be holding our annual Old Machinery Expo on the first Saturday in September at the Oakey Showgrounds.

In 2006, The Toowoomba and District Old Machinery Society Inc. held the second Queensland Heritage Rally (QHR) hosting over 300 engines, 300 tractors, 50 cars and trucks, 20 steam and many other exhibits.  We repeated hosting the QHR in October 2016.  In August 2025, TADOMS joined with Steaming on the Downs, and the Queensland Steam and Vintage Machinery Society, to host the 19th National Historic Machinery Association (NHMA) rally (“Steaming Under the Southern Cross”) at Kingsthorpe Park, between Toowoomba and Oakey.  This rally was awarded the Oakey Community Event Award at the Australia Day awards in January 2026.
