The Mandurah resident won three medals in the equestrian competition during the Pinjarra event on October 12.
His performance was notable considering he had back surgery late last year, which interrupted his training.
The 15-year-old started riding at six, but was riding competitively for the first time.
Cameron, who has special needs, is a member of Riding for the Disabled Association (RDA) Murray-Mandurah.
Cameron’s mother Diane said the competition was an important initiation.
‘Cameron really enjoyed the event and is keen to compete again next year,’ she said.
‘With more training, we are confident he will have even more success in the future.’
RDA Murray Mandurah president Belinda Brown praised Cameron’s dedication to riding.
‘He is very selfless and rode really well during the Special Olympics,’ she said. ‘He represented Murray-Mandurah with distinction and just loves riding.’
