A 15-year-old boy has been charged over the alleged gang rape of a six-year-old girl on Mornington Island.
The teenager allegedly assaulted the girl last April and has been charged under the Youth Justice Act.
Reports at the time alleged the girl was attacked by four teenaged boys aged between 14 and 16.
She was reportedly taken from an Aboriginal community on the island to Townsville Hospital after the attack.
A spokesman said the charges laid on Tuesday relate to that investigation.
It's understood investigations are continuing.
Mornington Island is the largest of the North Wellesley Islands group and has an indigenous population of more than 1000, primarily Lardil people.
