the purposes of public recreation or for enlarging the Park" The Park was transformed into a showground within the first decade. In 1921, the Brookvale Show was established with the formation of the Warringah Agricultural, Horticultural, Amateur Sports and Athletic Association. Between 1919 and 1928 children from Brookvale School planted trees to commemorate Arbor Day and it was the setting for school sports days and Empire Day picnics. During World War II, Brookvale Park was utilised by the Defence Force for training purposes. Since 1945 onwards On 25 April 1951, a new attendance record at Brookvale was set at 9,447, with spectators overflowing onto the field for a match between Manly and South Sydney. Over fifty annual shows were held at Brookvale Park before the show was moved to St Ives Showground. Trotting and ring events were features of early shows at Brookvale. The trotting track occupied a substantial area of the Park with lighting of the ring for night entertainment. Substantial improvements were later made to form a sporting oval by the addition of stands. Pavilions were constructed along Alfred Road to house show exhibits. Outside of the annual show period these pavilions were used for local church services and meeting rooms for the local community. They were also used by local bands as a place to practice. 'With the formation of the Manly-Warringah Rugby Club, known as the Sea Eagles, however, the situation changed. The horse events of the Show had to be transferred to an oval in Frenchs Forest because the horses’ hooves did too much damage to the turf of the rugby ground, and the Show itself ended its long association with the Park in 1992. The growth in popularity of the Rugby League competition led to the re-forming of the oval into a rectangular field in 1970–71, with major earthworks undertaken to form spectator ‘hills’ on the eastern and southern sides of it. Following this came the construction of simple but large concrete grandstands on the western and southern boundaries of the field, and finally the Ken Arthurson Pavilion that linked the two. The construction of these facilities necessitated the removal of the original grandstand and the various exhibition halls and show pavilion, and with that, the termination of their use by community organisations and their hiring out for social functions'.
