Senior Club (also known as Jimboomba Athletics) is available to all athletes turning 12 by December 31 in the calendar year.

Jimboomba Little Athletics can only provide external competition for athletes up to age U17.  However, there are many talented athletes at the centre who require wider competition, and want the opportunity to represent Queensland at the national championships and Australia at international events. Recognising this, the JLAC committee formed a close association with Jimboomba Athletics which is a senior amateur athletics club affiliated with Queensland Athletics and Athletics Australia. This partnership enables athletes who are aged over 10 to compete at events conducted by AA and QA associated organisations. It also enables athletes aged over 17 to compete at the club’s Friday evening competitions.

Over the years the club has had dozens of athletes compete at both Little Athletics and Senior athletics events and represent both their state and country.

Athletes who have won national titles and medals include Mitchell Fekete, Ben Roberts, Maddison Aitkin, Sam Windsor, Ashley Moloney, Tianah List, Camryn Newton-Smith, Talosaga Kia, Felila Kia, Motootua Kia, Sam Schmidt, Zac Macdonald, Brandon Sammut, Michaela Roberts, Lindsay Newton-Smith, Braelan Renton, Kyle Haslam and Jessica Pickles.

Past members of Jimboomba Athletics also include Olympians Genevieve Gregson, Camryn Newton-Smith, Ashley Moloney and Paralympian Torita Isaac.
