Baffin Bay Geological Survey has estimated that at least 13% of the world's undiscovered oil deposits and 30% of the world's undiscovered gas pockets are located in the Arctic, with the seas around Greenland potentially holding large amounts of natural gas and lesser amounts of crude oil and natural-gas liquids. Accordingly, the Greenland authorities have offered a large number of off-shore concessions for potential hydrocarbon (oil and gas) extraction. The largest concession-areas are located in seas west of Greenland; primarily in Baffin Bay and the Davis Strait, but with several smaller concessions in the Greenland Sea in the east also.

Major rivers of the division, from north to south, then east to west include the Clarence, Macleay, Hunter, Hawkesbury-Nepean, Shoalhaven, Clyde, Snowy, La Trobe, Hopkins, and Glenelg rivers. For administrative purposes, within the drainage division, the basins are generally classified into the following catchments, from north to south, then east to west: Australian south-east coast drainage division The south-east coast drainage division is the very long, narrow area of southern Australia between the Great Dividing Range and the Coral and Tasman seas, and the Bass Strait.
