Summary This IBA supports significant numbers of the endangered Swift Parrot and Regent Honeyeater in years when their favoured trees are flowering.

Site description Lake Macquarie is a large coastal lake north of Sydney. The Lake Macquarie IBA is defined as the southern edges of the lake, which support swamp mahogany, ironbark, forest red gum and spotted gum, which are key food species of Swift Parrot and Regent Honeyeater. This area covers the southern margins of the lake south of the town of Belmont, including Belmont Lagoon and Blacksmiths Reserves, from the lake to the sea; then between the lake shore and the Pacific Highway, south from the lake outlet at Swansea; then between the lake shore and the Sydney-Newcastle freeway to Dora Creek; then between the lake shore and Wangi Road north to Kilaben Bay. The area is primarily residential blocks with many large trees. Many coal mines extend under the IBA and there are two power stations.

Key Biodiversity Masked Owl; Ospreys nest regularly (this is the southernmost regular breeding site for this species in eastern Australia).
