SEQUEST was formed on August 1st, 2009, to provide a community-focused volunteer emergency radio monitoring group for members of the public who use CB radio and to improve services for the CB Radio network. In 2011, we moved into marine radio to improve coverage across Moreton Bay and surrounding inland waterways, particularly when local blue-water rescue groups are closed, or areas cannot be reached by radio. As an ACMA-licensed limited coast marine rescue station, we provide a maritime emergency radio communications service to all vessels. When SEQUEST was founded, the original name was Southeast Queensland UHF Emergency Team (SEQUET). The name "SERVICE" was added and later renamed to "SEQUEST". 2011 was a big year for SEQUEST.

Not only dealing with the flood disaster around southeast Queensland, but SEQUEST expanded its operations into the maritime radio network and obtained its first ACMA license "VND717", limited coast non-assigned. Dedicated to helping and assisting the maritime community and supporting volunteer marine rescue groups. During 2013, once again played a role in helping the community around Southeast Queensland. Volunteers put in tireless hours to keep social media services updated and staff radio emergency channels for calls for assistance from the Lockyer Valley to the Fraser Coast. In 2016, founder Shane Barnes was awarded the City of Ipswich Medallion in recognition of his valuable contributions to the Ipswich community. Shane was also nominated for the inaugural Queensland Volunteering Awards but was a runner-up. A year later, Jimboomba member Matt was nominated for Queensland Volunteer of the Year for his role during the floods that affected Jimboomba. Another milestone on the list was the purchase of the IPS06 UHF CB Repeater. In 2017, our Jimboomba base assisted with communications in the area following flooding from the Logan River caused by ex-TC Debbie. Over 100 calls for information updates were requested. The QLD Government invited our organisation to join the Emergency Volunteer Advisory Forum as a member.

SEQUEST has also been involved in many local community events such as Leukaemia Foundation's Light the Night, Brisbane Convoy for Kids, Oxfam Brisbane Trail walker, VMR Brisbane Community & Emergency Expo, Brisbane All Emergency Services Expo, and Marine Rescue Bribie Emergency Services Expo
