About Us.

The company was first established by Mel Ong in New Zealand under a different name during the early 1990s where major technical experience was garnered working with a prominent Auckland based contractor. Clients and projects included the Royal New Zealand Mint, University of Auckland, and Auckland Hospital as well as a few iconic factories.

​Years later OES as the company is now known in Perth, Australia; electrical engineering was added as a service. This effectively allows OES to provide our clients with ease and convenience, and for us to facilitate their requirements from design through to installation and completion.
