In the following year they issued rules for opening hours and the protection of flora in the park by impounding grazing animals and banning the cutting of grass and trees.

However, at this time the trees supplied by him were said to be growing well and the park was in good order with a drive and entrance gates and enclosed by a post and rail fence.

The Brisbane Botanic Gardens and Acclimatisation Society had also supplied fruit trees and flowering shrubs by 1875 and a house had been built for the Superintendent.

[2] Facilities built while the park was a government garden included a bush house erected in 1890 and a band rotunda constructed in 1891.

[1] In 1915, F W Turley, who had trained at Kew Gardens in England, was appointed as curator and began a number of works that are still prominent features of the park.

[1] In the 1930s Depression a number of large-scale works including the construction of walls, gates and terracing were carried out in the park by relief labour.

[1] In 1935, the Walter Burley Griffin Incinerator was constructed in the southern section of Queens Park to process the city's refuse.

In 1928 a service station was established on the northeast corner of the park and a section on the western side was used to construct the King George V memorial scout hall that opened in 1937.

[1] Queens Park has continued to develop and recent work has included the redesign of the menagerie as a nature garden and the reconstruction of an early bell gazebo that collapsed in the 1980s.

[1] The northern section of the original reserve is occupied largely by Ipswich Girl's Grammar School, though it contains two memorials and a striking pyramidal structure of limestone terracing alongside Brisbane Street.

The section in the centre is officially Queens Park and also contains the Walter Burley Griffin Incinerator, which is separately entered in the Queensland Heritage Register.

These are of a consistent and distinctive style and are constructed of rubble with stone capping and include walls, steps, terraces and several gateways with cylindrical posts.

Queens Park was one of three government reserves for gardens located at the early settlements of Ipswich, Toowoomba and Warwick, other of which were later established in a few other key regional centres.

It preserves examples of mature plantings, garden layout, stone walls, bush houses, rotundas and other park structures which reflect changes in ideas and usage over time.

Its natural landform of gentle slopes and elevated position contribute to the visual character of the town and important vistas can be obtained to and from the park.

It contains several major buildings of good quality design, such as the Burley Griffith incinerator, the sports clubhouses and the park curator's house and features many fine examples of stonework in local limestone.

It is also associated with the prominent Ipswich men who served as Trustees from 1862 until the last part of the 19th century and with architects M W Haenke and W Burley Griffith who designed buildings in the park.

[1] The Ipswich Nature Centre is located within the boundaries of the park and features a number of native animal species including tiger quolls, dingoes, southern hairy-nosed wombats, swamp wallabies, brush-tailed rock wallabies, red kangaroo, greater bilbies, emus, wedge-tailed eagles, lace monitors, spotted python, saw-shelled turtles and over thirty other species of birds, mammals and reptiles.
