Blue Lake National Park is a national park in Queensland, Australia, 44 kilometres (27 mi) east of Brisbane on North Stradbroke Island. Access is provided by road 9 kilometres (5.6 mi) west of Dunwich. Camping, open fires, and domestic animals are not permitted in the park.

Blue Lake

The park's main features is Blue Lake which is known as a "window lake" and is just under 10 metres (33 ft) deep when full. It is home to the southern sun fish. Water from the lake overflows into the Eighteen Mile Swamp. The aboriginal name for Blue Lake is Karboora.

Environmental studies have revealed the lake has been uniquely stable for thousands of years. Blue Lake was the focus for research on environmental change in which numerous indicators such as water discharge, water quality, pollen and algae samples were examined to understand the history of the lake.

Tortoise Lagoon

The ephemeral Tortoise Lagoon is also found in the national park. This small perched lake was 1.4 metres deep in 1974 when it filled.
