 In 1964 one acre (0.4ha) of land was purchased on the opposite side of McCulla Street, and a swimming pool was constructed and opened there in 1967, the school's centenary year.The school grounds were once again inundated by floods in January 1974, with the ovals submerged and water reaching halfway up the posts supporting Block G, where a painted mark reportedly indicates the flood level.In 1985 a new concrete retaining wall was built along Sherwood Road, and in 1990 Hall Street was widened and a new ramp and access path built.
