I appreciate your proactive approach of contacting the NT EPA for advice on appropriate remedial action, and encourage you to continue this practice should future instances require further clean-up efforts or investigation

Clint, I would like to express my thanks once again, both to yourself and your team that assisted with the incident on Sunday. The very prompt response, and professionalism shown on site when your crew arrived to a completely different situation than envisaged, was very much appreciated. Please thank Darren and his team that worked on site.

Diggamen did a fantastic job yesterday installing the routed timber signs at Karlu Karlu. The guys acted in a very professional manner and constructed the signs to the precise specifications.

"I wish to forward my appreciation for this signage works at ANZAC hill.
We had signage damaged at the last moment and had no options available to get new signs in from the supplier.
Diggamen went far beyond the normal signage requirement and got the job completed.
Staff observed the new signage was installed in time and on location with the protective cover of polycarbonate.
Well done Clint and the Diggamen team. Your efforts are appreciated "

Diggamen response times are quite exceptional and exemplary. Well done Clint Thomson, and thank you. I could cite numerous instances of prompt response times by the company from recent times. Their reliability and response times at fatal accident sites, truck rollovers and the like serve to make my job at these times just that much easier.

The course at Simpsons Gap looked magnificent with the cones and the clear signage. This is important for participants and I had some comments after that it was the best marked course they had seen. Along with the great scenery it made for a memorable event for everyone. So thanks.
