In 1927, legislation was enacted to grant the National Association perpetual lease of the grounds, at that time comprising just under . There followed a burst of ground improvements, mostly designed by architect Richard Gailey Jnr, including a dog pavilion, meat exhibition pavilion, more turnstiles and a new lavatory block in 1927; new horse and cattle stalls; and turnstiles at the corner of Costin Street and Gregory Terrace, in 1928. Also erected in 1928 were show pavilions for General Motors Pty Ltd, Brisbane Cars & Tractors Ltd, the Vacuum Oil Co. (concrete structure), and the Kodak Company Ltd, and a demonstration fibrous cement cottage designed by architect EP Trewern for James Hardie & Co. At this period the RNA sought to make the grounds a first-class venue for cricket, football and other sports, but had limited success in attracting the big matches. The year 1928 was a high point for the Association's sporting ambitions, with the showground the venue for the first England versus Australia cricket test in Queensland and the first in the 1928–29 series.

(Previously the creche was located on the main showgrounds north of Gregory Terrace.) The centre was operated by the Creche and Kindergarten Association and provided baby care while parents were enjoying the rounds of the show. In 1939, the Creche was removed to a new location near the Anglican dining hall, north of Gregory Terrace.

Although it was not uncommon for banks to establish agencies at showgrounds around Australia, this building is believed to be the only "exhibition" bank building specifically constructed for the Commonwealth Bank. The northeast end of the building was extended in 1947. Despite the severe economic depression of the
