Lake Cathie is a town in New South Wales, Australia about 15 minutes drive south of Port Macquarie. At the 2011 census, it had a population of 2,998.
The town is a popular holiday destination on the Mid North Coast because of its tranquil location which hosts the lake, lagoon and beaches. It has a Woolworths supermarket, local Tavern, Lake Cathie Bowling Club, bakery, fish & chip shop, coffee shop, pharmacy, post office, a newsagent and a bargain shop. Its main feature is a tidal lake fed by the ocean daily. Several time throughout the year the lake is closed over by shifting sands and becomes dark in colour due to the tannins in local flora. Tourism centres on the lake as it is a popular swimming and fishing spot all year round especially when the lake is open.
