The Team Behind Yangga Civil

Colin McLennan is a Senior Jangga Traditional Owner who provides strategic oversight and cultural leadership across all of Yangga Civil's operations. He ensures culturally appropriate influence across workforce recruitment and development, and is the driving force behind the company's vision to become one of Queensland's leading Indigenous-owned civil construction businesses.

Chris Sariman leads the strategic, commercial, operational and financial performance of Yangga Civil. With extensive experience delivering road works alongside Traditional Owner personnel on Department of Transport and Main Roads (TMR) projects, Chris has mentored and trained numerous Indigenous operators — building operator capability, road construction skills and supervisory experience within live TMR delivery environments.

Nicole Kwarcianyi oversees corporate operations, financial management, governance, contract administration, compliance and business systems across Yangga Civil. Her leadership ensures the company maintains the governance standards and operational rigour required to deliver Tier 1 standard infrastructure services for local and regional councils.

Bon McLennan manages project mobilisation, workforce scheduling, procurement, plant and equipment logistics, resource allocation and site support. His hands-on coordination role ensures that the right people, plant and materials are in place to deliver projects safely and on schedule across remote and regional Queensland.

Jessica (Jess) Milloy is the dependable administrative backbone behind Yangga Civil's leadership team. She makes sure tenders go in complete and on time, records are accurate, contractors and suppliers are organised, and leaders and field crews have what they need to keep work moving safely. Jess independently runs the day-to-day operations of Bulgon Lodge in Collinsville for Jangga Operations, and supports Yangga Civil's executives with tender preparation, compliance documentation and corporate administration.

Tatiana Suangin is Yangga Civil's single point of accountability for quality on each project and the main quality contact for the client. She has hands-on experience on Queensland TMR projects across road construction and bridge strengthening and remediation, delivered with RoadTek and AECOM. Tatiana has also supported Central Highlands Regional Council works on the Dawson Developmental Road pave and seal project — giving Yangga Civil a CQR who knows Council's quality expectations first-hand.
