Production commenced in September 2005, producing at an initial flow rate of approximately 60–80 terajoules per day. Following an upgrade of the existing Varanus Island facilities, the processing capacity will increase to approximately 240 terajoules per day.

The John Brookes gas field will initially produce around 180 terajoules of gas per day and 850 barrels of condensate per day. The field will has three production wells producing to an unmanned platform.

Raw gas is sent to the Varanus Island processing facility via a 55 kilometre 18 inch multiphase pipeline where condensate is removed and stored and the raw gas is processed into sales quality gas. 

The sales gas is sent to mainland Western Australia via two 100 kilometre sales gas pipelines which connect into the Dampier–Bunbury and Goldfields Gas Transmission trunklines.
