The preservation of soil and water underpins everything that we do at PSK.

We honour our mission by delivering technical excellence for each and every client we work with. But we don’t stop there. We believe that our knowledge and passion should be shared with the broader community; to guide, connect and thrive.

We have a lot of fun and love what we do.


The late Henry Parsons, a founding Director at PSK, enjoyed Greek philosophy and designed PSK’s logo using alchemy symbols. He chose the alchemy symbols for earth and water which represent the key elements that PSK aims to preserve through our consultancy services.

Henry chose the colour maroon to represent the rich red soils commonly found in Queensland.
