Newton is one of the UK's leading consulting firms, known for its data-driven, results-focused approach to solving complex business challenges. We partner with organisations across the public and private sectors to deliver measurable, sustainable improvements through a distinctive commercial model: our fees are contingent on delivering agreed outcomes.
As Newton expands into Australia, this is a unique opportunity to join at a pivotal stage of growth. You will help build our Australian business by developing trusted client relationships, leading high-performing teams, and delivering lasting outcomes for defence clients.
Our teams lead intensive diagnostics and multi-year transformation programmes, taking end-to-end responsibility for identifying opportunities, designing solutions, and embedding sustainable change.

· Working closely with programme leads to ensure workstream KPIs are aligned to client organisational outcomes and wider transformation objectives
· Working on site in different Australia locations, day to day with client counterparts to review progress, problem-solve and drive performance improvement, while building lasting client capability. We are happy for you to be based anywhere in Australia with a good airport nearby.
· Creating clear, compelling and data-driven stories for stakeholders – from frontline managers through to senior leaders and executive sponsors – and working with programme leads to remove blockers to progress
· Proactively adjusting delivery, resourcing and commercial plans in collaboration with programme leadership to keep workstreams and programmes on track
· Identifying opportunities for future work within your client area and supporting wider account and market engagement activities alongside programme and account leadership
