Christine

Christine first joined Oaktree in 2015, volunteering in various roles before stepping in as Head of International Engagement in September 2017. She knows that young people are a passionate and capable bunch, and play a crucial role in creating a fairer, more equitable world. Christine loves working alongside our partners in the Asia-Pacific region, and is most excited about work that shifts power structures and challenges the status quo. When not at Oaktree, you can find Christine studying a Master of Public Health, eating delicious, locally grown food, and roller-skating by the beach.  

 Esther Wan

Chief Financial Officer

Contact: e.wan@theoaktree.org

Esther has followed her father's footsteps to pursue a career in Accounting. She can't seem to run away from volunteering her time to causes she believes in, co-founding The Village School Project when she was still in her teens. She loves creating beautiful things in Microsoft Excel, namely lists. What are her plans for the future? You may find that in an Excel sheet.   

Stacey Batterham

Head of Campaigns

Contact: s.batterham@theoaktree.org

Stacey started at Oaktree in 2014, working on the End Poverty Roadtrip. Over the last four years, Stacey has worked on mass mobilisation campaigns and political advocacy, engaging thousands of Australians on issues around poverty and aid.

Amy Pearce

Head of Marketing and Fundraising 

Contact: a.pearce@theoaktree.org


Amy joined Oaktree in 2016 and comes from a background in digital and print marketing. When she's not pitching for innovative strategies around fundraising, marketing or communications, you can find Amy sitting in the sunshine or talking about the sunshine on a cloudy day. Amy may be one of our newest members on the team, but her motivation and passion towards young people and the power they have to create change is at the forefront of her work.
