As a licenced electrician, John identified a gap for quality trade services in the Darwin market back in 2009. 

Having moved to the Top End from the Queensland coast, John started Johnny Cool with just a mate and his own son as an apprentice. John has grown the company from 3 to over 60 employees at its height. 

With construction of the Inpex LNG gas plant completed, Johnny Cool now boasts a team of 5 on the gas plant, with another 20 based in our Berrimah premises. 

John still oversees operations each day but rather than spending his time on the tools, John (reluctantly) now spends his days desk-bound preparing quotes and project scopes. 

His 30 plus years experience in the industry is a valuable and competitive edge for Johnny Cool.
