Indigenous high school students in Brisbane are graduating at the same rate as non-Indigenous students, making the Queensland capital the first to close the gap in Australia.

The Queensland Government has reported more than 98 per cent of Indigenous students, or 268 people, successfully completed Year 12 in Brisbane, compared to 94 per cent of non-Indigenous students, or 7,105 people.

Across the state, 94 per cent of Indigenous students, or 1,753 people, got their leaving certificate compared to 95 per cent non-Indigenous, or 26,644 people.

Last year, 86 per cent of Indigenous state school students successfully completed Year 12.

That means an extra 209 Aboriginal and Torres Strait Islander students graduated high school, up to 1,753 from 1,544 in 2014.

Education Minister Kate Jones said more Aboriginal and Torres Strait Islander students had successfully completed Year 12 than ever before.

"Here in Brisbane when it comes to Year 12 attainment we have well and truly closed the gap," she said.

"We know that a quality education transforms lives so closing the gap on Year 12 attainment for Aboriginal and Torres Strait Islander students is crucial."

Ms Jones said there was still more to be done to improve Year 12 retention rates.

For Indigenous students, the number of Year 10s who go on to complete Year 12 increased from 64.3 per cent in 2014 to 66.7 per cent in 2015, however that was well behind the retention rate of 83 per cent for non-Indigenous students.

"We are working hard to turn this around by providing additional help from Year 11 to support students through the senior years of school," Ms Jones said.
