naval base to Fort Cornwallis, the tiny island made its debut in the colonial records in 1797. The idea for the military post is to protect the new township of Jamestown (now known as Bayan Lepas) for any attack. However, the plan was delay due to serious malaria outbreak. When the British found that Georgetown to be in a better position to make a profitable port, Pulau Jerejak naval base project was totally abandoned.

In 1900, Pulau Jerejak was turn into a quarantine centre as Penang started to experience growth. Many immigrants who flooded Penang at that time were sent to Pulau Jerejak for health inspection.

rampaged the centre destroying several buildings. Luckily the, officer in the centre are able to contain the problem without much difficulties.

A year later, Pulau Jerejak saw an upsurge of detainees due to more and more drug related menace. Due to more prisoners and as a security measures, fisherman from nearby island were prohibited from going near to the island (not more than 200m from Jerejak beach). There are few incident of inmates reported being escape from the island and the exact escape routes are still remains a mystery. Prior to the prison closing down in 1993, all the inmates were transferred to Johor. The last group of inmates left the island on 13 August 1993.
