At Sleeman Sports Complex, the Brisbane Aquatic Centre’s indoor Olympic pool is 50 metres long.
The Brisbane Aquatic Centre in Chandler contains a 50-metre indoor Olympic pool, built for long-course competitive swimming. It also has a separate 50-metre outdoor Olympic pool, so the answer refers specifically to the indoor facility rather than to the centre’s smaller lap or diving pools. The indoor pool is listed with a depth of 2 metres.
Sleeman Sports Complex was purpose-built for Brisbane’s 1982 Commonwealth Games and has since become a major Queensland sports venue. The aquatic centre hosted swimming, diving and other events during Brisbane’s sporting history, while the wider complex also includes cycling, gymnastics and arena facilities.
A common mix-up is choosing 25 metres, because the centre also has a 25-metre lap pool and a 25-metre diving pool. Those are separate facilities. Olympic-standard swimming pools are generally 50 metres long for long-course racing; 25-metre pools are used for short-course competitions.
