Chapman Description The slender-billed thornbill is a small bird, with head and body length of 9-10 cm. The upperparts are light olive-grey to dark olive-brown. The rump and base of tail are buff-yellow to yellow-olive. The forehead and cheeks are scalloped and flecked pale to deep cream. The underparts are uniformly cream-white to cream-buff. The bill is dark and the eye pale.

  • Regional Internal Migration Estimates, Provisional, March 2021
    3 August 2021 Regional Internal Migration Estimates, provisional, March 2021 In the year to March 2021 there was a recovery in the number of interstate moves, with 371,000 people moving interstate compared with 354,000 moves in the year to December 2020. This recovery was driven by the highest number of interstate moves for a March quarter since 1996, with around 104,000 people moving. Close to a quarter of the increase in interstate moves was driven by increased departures from Victoria, as Melbourne exited its second lockdown in November 2020. This was due to an outflow of 28,500 people from Melbourne to the eastern states, with the majority of people leaving Melbourne settling in regional Victoria. Net internal migration for regions outside the capital cities continued to increase, with net migration of 44,700 people in the year to March 2021. The number of capital city residents moving to the regions is now higher than it was prior to the onset of the pandemic (244,000 departures compared with 230,000 in March 2020). The recovery in the number of people moving interstate has affected states and territories differently, with smaller states seeing fewer departures, reversing recent historical trends. Net interstate migration has slowed due to COVID, but started to recover in March 2021 Since the onset of the COVID-19 pandemic net interstate migration has fallen from a high of 404,000 in June 2019, to a low of 354,000 people in December 2020. Interstate migration has started to recover with 371,000 people moving interstate over the year to March 2021.

    Soils of the Northern Territory | factsheet Soils are developed over thousands of years and are made up of air, water, minerals, organic material and microorganisms. They can take on a wide variety of characteristics and form ecosystems which support all life on earth. In the NT, soils are an important natural resource for land-based agricultural industries.

  • European Discovery and South Australian Administration of the Northern Territory
    3 Prior to 1911: European discovery and South Australian administration of the Northern Territory The first of five time periods that will be used to structure this account of the development and deployment of vocational education and training in the Northern Territory covers the era when European explorers initially intruded upon the ancient Aboriginal tribal lands and culminates with the colony of South Australia gaining control of the jurisdiction. Great Britain took possession of the northern Australian coastline in 1824 when Captain Bremer declared this section of the continent as part of New South Wales. While there were several abortive attempts to establish settlements along the tropical north coast, the climate and isolation provided insurmountable difficulties for the would-be residents. Similarly, the arid southern portion of this territory proved to be inhospitable and difficult to settle. As part of an ongoing project of establishing the borders of the Australian colonies, the Northern Territory became physically separated from New South Wales when the Colonial Office of Great Britain gave control of the jurisdiction to the Government of the Colony of South Australia in 1863 (The Parliament of the Commonwealth of Australia 1974, p. 83) following the first non-Indigenous south to north crossing of the continent by the South Australian-based explorer John McDouall Stuart in the previous year. 35 VocatioNAL EducatioN ANd TRAiNiNg On the political front, in 1888 South Australia designated the Northern Territory as a single electoral district returning two members to its Legislative Assembly and gave representation in the Upper House in Adelaide. Full adult suffrage was extended by South Australia to all Northern Territory white residents in 1890 that demonstrated an explicit and purposeful disenfranchisement of the much more numerous Asian and Aboriginal populations.

This had, and will have into the future, a number of impacts that belie the effect of a seemingly low proportion of aged persons in the Territory population. Treasury: Northern Territory Demography Presented the following unique features of the NT population: - • The NT population has a very different age distribution to the Australian population (see graph below), with more children, young adults and fewer old people. However, the NT’s population has been aging just as fast as the national population in terms of average age.

  • Australian States and Territories Suicide Data 2019 (ABS, 2020)
    Australian states and territories suicide data 2019 (ABS, 2020) Released, 23 October 2020 Notes about this summary: Victorian data ─ Care needs to be taken when interpreting data derived from Victorian coroner-referred deaths including suicide (Victorian and national mortality datasets). ─ In the first quarter of 2020, the ABS and the Victorian Registry of Births, Deaths and Marriages (RBDM) undertook a joint investigation aimed at identifying death registrations that had not been submitted to the ABS as part of usual processing procedures. ─ This investigation identified 2,812 deaths that had been registered in 2017, 2018 and 2019, but had not previously been provided to the ABS. These deaths were not reported because of an issue associated with the Registry's previous processing system which was replaced in early 2019. ─ The ABS has made a permanent time series adjustment to statistics for suicide deaths. The additional death registrations for 2017 and 2018 have been placed back in their respective registration years. ─ This time series change is associated with an administrative processing issue rather than a true change in the prevalence of suicide deaths. Australian Capital Territory suicide data 2019 (ABS, 2020) Number of deaths ACT, 53 NT, 50 TAS, 108 Australian Capital Territory in 2019 ‒ 53 people died by suicide in the Australian SA, 251 Capital Territory (41 male, 12 female), which is an increase on the 47 recorded in 2018.

  • 19. Liberty Square
    19. Liberty Square Liberty Square was named by the Darwin Town Council in June 1919 to commemorate the ‘Darwin Rebellion’ of 17 December 1918. That rebellion, which culminated in a protest directed at Government House by hundreds of workers on this site, and the unrest leading to it, resulted in a 1919 Royal Commission into the Administration of the Northern Territory conducted by Justice Norman Kirkwood Ewing (1870-1928). On the western side of Liberty Square is a memorial cairn at the place where the sub-sea cable from Banjowangie (Banyuwangi) Indonesia was joined with the Overland Telegraph Line to revolutionise communications in Australia on 20 November 1871. Towards the eastern side is a plinth and plaque commemorating the scientific achievement of Pietro ‘Commendatore’ Baracchi who, in collaboration with colleagues in Singapore and Banjowangie, established true longitude of Port Darwin and other Australian colonial and New Zealand capital cities in 1883 in the grounds of the Port Darwin Post Office and Telegraphic Station (now Parliament House). On the eastern side near the Supreme Court is a Banyan tree, which is valued by the community as a remnant of the original Darwin foreshore vegetation. It is over 200 years old and was the congregation point for Larrakia youths prior to ceremonies that took place under the nearby Tamarind tree. Liberty Square was the site for the original Darwin Cenotaph, which is now located on the old Darwin Oval on the Esplanade. History Sub-sea Telegraph Cables From the 1850s telegraph technology was very quickly taken up by the Australian colonies, building networks across their own territories, and then soon connecting to each other.
