About Combined Services Group
Combined Services Group exists to solve one problem: Pacific operators who need dependable underwater expertise with no compromise on safety. From our headquarters in Denarau, Nadi, we coordinate commercial diving and underwater engineering across Fiji and the wider Pacific.
What makes us different is the combination that few can deliver: deep local Pacific knowledge paired with international certification standards. We understand the waters, the logistics, and the conditions across Fiji, Vanuatu, Solomon Islands, Papua New Guinea, and Samoa, and we hold our work to engineering-grade reporting and a safety-first culture on every dive.
