Dixon is employed by the Melbourne Storm - the Falcons' NRL affiliate - but will relocate to the Coast this week to take up his new position.
The Sunshine Coast has won just two of 11 games this year and leaked a total of 145 points in its past three matches.
Dixon will play an advisory role in overseeing the Intrust Super Cup club's coaching staff and operations.
Falcons chairman Ashley Robinson said: "We understand that we are understaffed and underfunded and we are bringing him in to help mentor the coach (Glen Dreger) and the players."
Club chief executive Chris Flannery described Dixon as a key acquisition.
"He has a wealth of rugby league knowledge and experience after working under Wayne Bennett at the Brisbane Broncos for 10 years and then coaching overseas at the Celtic Crusaders in the English Super League for four years," he said.
"He will be a great addition to our coaching team and I am sure that all of our staff will appreciate having someone with John's vast experience in their corner."
Dixon, also a former coach of Redcliffe, will relieve some of the strain on Dreger.
Flannery said: "The hours that an Intrust Super Cup head coach is required to put into managing and preparing the team to play these days are very significant.
"We have brought in John to take some of the work
load from Glen Dreger, who is also a very successful NRL development officer on the Sunshine Coast".
Since taking over from Ivan Henjak midway through last season, Dreger has coached the team to three wins from 24 matches.
Dreger said he envisaged having a strong working relationship with Dixon as they tried to turn the ailing club's fortunes around.
"I look forward to working closely with John over the next 14 weeks of the competition, and hopefully beyond, to get this club back to the top of the Intrust Super Cup table," he said.
"John's experience will be invaluable to me and all of our coaching staff here at the Falcons, and we are looking forward to learning from him over the next few months."
Dixon will travel to Rockhampton with the state league side this Saturday.
