environmental consulting for Mining, Quarrying & Civil Construction in Queensland

Practical, plain English environmental advice without the big consultancy price tag.


"It seems to me that the natural world is the greatest source of excitement; the greatest source of visual beauty; the greatest source of intellectual interest. It is the greatest source of so much in life that makes life worth living."

— Sir David Attenborough

RiethThink Environmental Solutions is a Queensland-based environmental consultancy founded on a simple idea — that environmental compliance should be practical, embedded into how you operate, and actually make sense to the people doing the work.

We're a small, nimble team based in Logan City, and we work directly alongside businesses across South East Queensland, the Scenic Rim, and the Darling Downs. Our clients are miners, quarry operators, civil contractors, and rural landholders who need reliable environmental support without the overhead of a large firm.

We cover the full project lifecycle — from initial approvals and management plan development through to ongoing monitoring, regulatory reporting, and rehabilitation. Whether you need someone embedded in your site team or just need a specific piece of work done well, we're here to help.
