In his first official coaching gig, Symonds will share the reins with ex-Queensland and Australian Country mentor Vic Williams for the Under 19s tournament to be held from January 12-22.
Williams said the Townsville-based Symonds would link with the recently named squad before they flew out to Adelaide.
"Many of these young blokes are at the stage where they are getting ready to take the next steps into Premier Grade cricket and possible state squads so Roy will have plenty to teach them about that," Williams was quoted as saying by the Australian AAP news agency.
The Queensland squad features Australian Under-19 selections Tom Healy - son of former Test wicketkeeper Ian Healy.
Symonds had announced his retirement from professional cricket in 2012, citing family reasons.
Symonds was embroiled in the biggest controversy of his career after alleging that India off-spinner Harbhajan Singh racially abused him in the Sydney Test in 2008.
