Situated 82 kilometers north-northeast of the Sydney CBD, the suburb of Lake Munmorah is a peaceful residential enclave renowned for its picturesque coastal landscapes, serene waterways, and extensive outdoor activities. Nestled near pristine beaches, national parks, and tranquil lakes, the area is highly valued for its boating, fishing, and walking trails, offering a relaxed lifestyle comparable to neighboring Mannering Park. The demographic profile is characterized by a high proportion of retirees, older Australians, and couples without children. Residents generally present lower qualification levels and sit within the lower income quartiles. The local housing market is defined by a strong level of outright home ownership, a high concentration of detached houses, and constrained property supply. As of May 2026, the estimated resident population of the suburb of Lake Munmorah stands at approximately 5,165. This current figure, derived from annual SA2-level estimated resident population statistics and quarterly national address updates, represents minimal growth since the 2021 Census when a population of 5,084 was recorded. While overall population expansion remains subdued, the area is experiencing a notable demographic aging trend, highlighted by a significant and growing presence of residents in the 75 to 84 age bracket and an elevated proportion of individuals aged 85 and over. This aging profile aligns with strong industry projections for future services sector employment, even as the community maintains a quiet and stable growth trajectory.
Estimated residents are up from 5,084 at the 2021 Census — a change of 81 people, or 1.6%.
