Mental health and suicide prevention were the focus of a fight night in Cleveland on Saturday.
The Quandamooka Cup drew over 700 people and raised a substantial amount of money for the charity Beyond Blue.
The event also paid tribute to North Stradbroke Island teen Jai Burns.
Martial arts and Muay Thai boxers from Brisbane and the Gold Coast slogged it out in 16 fights during the event at the Cleveland showgrounds.
Promoter Warren Westerberg said the youngest fighters were seven and eight-year-old brothers Jesse and Jack Johnstone from Muay Thai Mulisha, who were trained by their father Chris Johnstone.
The oldest fighter, 56-year-old Tony Hallovich of Southern Stars Muay Thai entered to tick off an item on his bucket list and because he wanted to support the event.
Also competing was Strikeforce Muay Thai Gym’s Aaron Leigh, a two-time world champion, came out of retirement to fight in the Quandamooka Cup.
A fighter in the main event Mark Sarracino, an Australian who lives in Thailand, is a multiple national title winner.
Boxers from Supajai Gym, named after the Straddie teenager, also competed.
Mr Westerberg said everyone involved in helping to organise and host the event had done it on a volunteer basis.
This included about 40 volunteers from Redlands Martial Arts Academy, led by instructor Shane Degney, who helped with the event, including setting up and pulling down the venue.
Mr Westerberg also recognised Punish, a Gold Coast company that provided fight gear, including an Aboriginal-style handpainted boxing glove, which was auctioned on Saturday.
Kev Stephenson from Beyond Blue attended and spoke about their work and his own experiences.
The event raised awareness about mental illness, bringing it into the open and showing people they are not alone.
Mr Westerberg said many of the fighters suffered from depression or anxiety or had family members or friends who had committed suicide.
