Who We Are

Reece and Peta are Directors of OG Diesel NQ. Reece's journey began as a kid who loved to work on his bikes and cars, pulling them apart just to figure out  how everything worked. Now, as a fully qualified diesel mechanic with over 15 years of experience in the diesel mechanic industry, he has developed a deep understanding of diesel engines and repair techniques. Combining his hands-on experience and passion for his job!


Peta is the brains of the workshop, focusing on finance, customer bookings and parts ordering for a smooth running business. Peta has a passion for growing the small family business by prioritising quality, reliability and customer satisfaction.


We’re fortunate to have three enthusiastic and skilled staff members in our small family business–Mike, Kane and Lachlan. Each of the guys has a deep passion for all things diesel and mechanical. They frequently spend their weekends working on their own vehicles, or enjoying camping and fishing experiences in FNQ.


Whether you're running heavy machinery, light vehicles or an entire fleet, OG Diesel NQ is here to keep you moving.
