This 51.5m geothermal-heated outdoor competition pool with a 1.5m wide movable bulkhead was built for St Hilda’s Anglican School for Girls, an independent day and boarding school in Mosman Park, and remains a centrepiece of the school’s sport and aquatics program. Widely regarded as one of the best school aquatic centres in Australia, a novel feature of the design is the spectator seating protected with coloured Danpalon-clad wind breaks. All pool plant and store rooms are located below the pool concourse.
