Some Kind Words From Our Customers

Our customers think that we provide some of the most outstanding surveying services in the Adelaide area, from property divisions and estate development to civil works and commercial projects. But you don’t have to take our word for that, just take a look at some of the many glowing testimonials that we regularly receive and decide for yourself.


“I recently completed my third subdivision with Sawley Lock O’Callaghan. I have returned each time because the service is exemplary. I encountered many problems during the developments, yet the team at Sawley Lock O’Callaghan were able to liaise with Councils and other professional bodies to provide a solution on each occasion. As a developer, I required assistance in many areas, specifically local knowledge and attention to detail. My questions were replied to promptly and in a manner that was easily understood. Fee structures were very reasonable and well documented at the start of the process. All drawings provided were of a very high standard. My initial thoughts when I started land development were of great concern with so many potential pitfalls. The Sawley Lock O’Callaghan team have provided great comfort with positive interaction from start to finish.”

“On-going support”

“We appreciate the on-going support we receive from Sawley Lock O’Callaghan as a survey services provider to HDS Australia, especially the extra effort you put in when quoting (often at short notice) to ensure the project scope is well defined and achievable.”

Managing Director
HDS Australia

“You guided us”

“Thank you for the efficient way you guided us through the subdivision of our block. We finally completed the subdivision, and the block sold three weeks after going on the market. We appreciated your assistance very much.”

“It is such a change to deal with people who are professional, helpful and pleasant. Of the four times we have used Sawley Lock O’Callaghan, it has always been the same, and it happens all too rarely these days. It was very much appreciated”

“diligent, thorough, intelligent, insightful and tireless”

“I engaged Sawley Lock O’Callaghan for my subdivision project in 2015. They were fantastic to work with – diligent, thorough, intelligent, insightful, and tireless. They were extremely professional. As the project manager for my project, Max was always willing to listen yet never shy to give honest feedback. When we had certain issues with one of the government departments Max went out of his way in helping me to negotiate a lower fee hence saving me thousands of dollars. His expert technical know-how and vast experience helped my subdivision go through smoothly. I have thoroughly enjoyed working with Max and Sawley Lock O’Callaghan and will use them again in a blink of an eye.”
