 The school committee and labour under the Unemployment Relief Scheme were responsible for much of the ground improvement works.The Great Depression, commencing in 1929 and extending well into the 1930s, caused a dramatic reduction of building work in Queensland and brought private building work to a standstill.In response, the Queensland Government provided relief work for unemployed Queenslanders, and also embarked on an ambitious and important building program to provide impetus to the economy.
