Maroons coach Kevin Walters confirmed the additions of the four former Maroons as part of a "fresh approach" ahead of Queensland's 2019 campaign.
Hodges will join Camp Maroon as an assistant coach, while Civoniceva comes in as a team manager.
The recently retired duo of Thurston and Slater will be involved in a coaching and mentoring capacity throughout different stages of the series.
Together, the decorated Queensland quartet played an astonishing 125 State of Origin matches for the Maroons and are outstanding role models and community leaders.
