Sydney Basin
–
The Sydney Basin is both a structural entity and a depositional area, now preserved on the east coast of New South Wales, Australia and with some of its eastern side now subsided beneath the ocean. It has also lost area on its side by erosion. The Sydney Basin consists of Permian and Triassic sedimentary rocks and it is named for the city of Sydney which is centred within it and stretches from Newcastle in the north to Batemans Bay in the south, and west to the Great Dividing Range. The basin is home to the major centres of Newcastle and Wollongong. Sydney’s famous harbour and the cliffs of the Blue Mountains are signature formations of relatively hard upper strata of sandstone. The basin contains the UNESCO World Heritage-listed Greater Blue Mountains Area, definitions of the boundaries and what comprises the Sydney basin vary significantly. The Australian Government classifies the basin as an interim Australian bioregion consisting of 3,629,597 hectares, according to NSW Primary Industries, the basin extends through approximately 350 kilometres of coastline from Newcastle in the north to Durras Lake in the south. From Durras Lake the western boundary continues in a line through Lithgow to around Ulan, to the north the boundary extends 120 kilometres along the Liverpool Range to a point 80 kilometres north of Muswellbrook, and then runs 200 kilometres back to the coast at Newcastle. To the east the basin continues to the edge of the continental shelf, the total area of the basin is approximately 44,000 square kilometres onshore plus 5,000 square kilometres offshore. The centre of the basin is located around 30 kilometres west of the Sydney central business district at Fairfield, in addition, some of the rivers of the Hunter-Central Rivers catchment and the Southern Rivers catchment also lie mainly in the basin. In the Hunter-Central Rivers catchment, the Hunter River sub-catchment forms the boundary of the basin. In the Southern Rivers catchment, the Illawarra sub-catchment and the Shoalhaven sub-catchment forms the southern boundary

Hierarchy
–
A hierarchy is an arrangement of items in which the items are represented as being above, below, or at the same level as one another. A hierarchy can link entities either directly or indirectly, and either vertically or diagonally, indirect hierarchical links can extend vertically upwards or downwards via multiple links in the same direction, following a path. This is akin to two co-workers or colleagues, each reports to a superior, but they have the same relative amount of authority. Organizational forms exist that are alternative and complementary to hierarchy. A hierarchy is a system or organization in which people or groups are ranked one above the other according to status or authority, Hierarchies have their own special vocabulary. Most hierarchies use a more specific vocabulary pertaining to their subject, for example, with data structures, objects are known as nodes, superiors are called parents and subordinates are called children. In a business setting, a superior is a supervisor/boss and a peer is a colleague, degree of branching refers to the number of direct subordinates or children an object has a node has). Hierarchies can be categorized based on the degree, the highest degree present in the system as a whole. Categorization in this way yields two broad classes, linear and branching, in a linear hierarchy, the maximum degree is 1. In other words, all of the objects can be visualized in a lineup, note that this is referring to the objects and not the levels, every hierarchy has this property with respect to levels, but normally each level can have an infinite number of objects. An example of a hierarchy is the hierarchy of life. In a branching hierarchy, one or more objects has a degree of 2 or more, for many people, the word hierarchy automatically evokes an image of a branching hierarchy. Branching hierarchies are present within numerous systems, including organizations and classification schemes, the broad category of branching hierarchies can be further subdivided based on the degree. A flat hierarchy is a hierarchy in which the maximum degree approaches infinity. Most often, systems intuitively regarded as hierarchical have at most a moderate span, therefore, a flat hierarchy is often not viewed as a hierarchy at all. For example, diamonds and graphite are flat hierarchies of numerous carbon atoms which can be decomposed into subatomic particles. An overlapping hierarchy is a hierarchy in which at least one object has two parent objects. Pseudo-Dionysius used the related Greek word both in reference to the hierarchy and the ecclesiastical hierarchy

Yora languages
–
The Yuin–Kuric languages are a family of mainly extinct indigenous Australian languages that existed in the south east of Australia. They belong in the Pama–Nyungan family and these languages are divided into the Yuin, Kuri, and Yora groups, although exact classifications vary between researchers. Yuin–Kuric languages were spoken by the inhabitants of what are now the cities of Sydney. The Yora or Iyora group is accepted by Dixon, dharug, an extinct language which attempts are being made to revive. They were spoken in the region of Sydney, jeremy Steeles partial reconstruction of the Sydney language includes a comparison of pronouns in several Yuin–Kuric languages. The following partial and simplified version shows some of the similarities and differences across the family
