Managing Director

Hi, my name is John Diakomanolis, Managing Director of One Call Venue Services.


I’ve been working within the Gaming Industry for almost 20 years and began my career facilitating and overseeing EGM Installation works & Gaming Room Developments for the Tatts Pokies Network….

”The man on the ground, so to speak”

My role quickly escalated, and as Senior Service Delivery Manager for the Victorian Gaming Network my passion to improve service solutions for Gaming Venues matured.

With highly developed skills in Gaming Room Fitouts & Refurbishments, Project & Service Management, AutoCAD, Product Development, Joinery Design and Electrical Cabling, life took me onto the path of starting my own company and so “One Call Venue Services” was born.

My goal is to deliver great services and quality products for our customers, with a strong focus to continually improve project costs for Gaming Room Fit Outs for all Gaming Venues across Australia.

I’m a strong believer that you shouldn’t have to pay excessive prices just because the sign out the front says “Pokies”
