Billie-Jo Barbara

Chief Human Resource Officer

Department for Child Protection

(New nominee)

As an outcomes-focused executive and board director with a track record in complex leadership and organisational transformation, my point of difference is the ability to get even the most challenging of team members or director colleagues to align to the vision and accomplish what is required.

Drawing upon almost 20 years of experience across the value chain of HR and business operations, I connect strategy with execution – translating challenging mandates into actionable strategies and initiatives that deliver targeted stakeholder outcomes, often in sensitive and/or legacy landscapes, where a future culture of achievement is needed.

Focused on people, performance (including financial), leadership development and capability, I look across the span of opportunities, whilst appropriately managing quality and risks. I connect stakeholder groups with purpose and the bigger picture, identifying and mapping out tangible pathways and plans to transition into the future. Underpinned by additional skills in organisational-wide workforce planning, proven success in change management, risk and governance, I bring the influence, acumen and credibility needed to deliver on key priorities.

Attributes that Billie-Jo will bring to the Divisional Council:

  • Has chaired two NGO boards and sat as a non-executive director of two NGO boards in total and sat on various executive and oversight committees, including as a current member of the Department for Child Protection’s Senior Executive Group.
  • Experienced in governance, and as a executive within the sector whilst also but also brining a range of other contributing skills such as oversight of corporate services, HR, strategy and business planning functions.
