Tania Taylor, Volunteer Coordinator

Tania arrived in Australia in 2004 from South Africa and thought she was set to pack her suitcases away and settle in her new country.  Life had other ideas though and after 2 years she found herself back on a jet heading to Suriname, a country she knew nothing about.  After 2 years adapting, Tania's next move was on the cards and she spent 12 months in Montreal followed by 2 years in Mozambique.  Tania was very privileged to land a volunteer stint for an orphanage in Mozambique and given the difficulties surrounding the children, found herself becoming an untrained "Bob the Builder" joining a volunteer team physically building an orphanage in a 3rd world country.  Finally, she returned to Australia where her suitcases now collect dust!

Tania joined PACT in 2017 as a volunteer, progressed to the Administration Officer and has since added the title of "QLD Volunteer Coordinator" to her portfolio where now spends her days making the "business" of volunteering as smooth and easy as possible for all those invaluable volunteers who selflessly give of themselves every day.   When Tania is not coordinating volunteers, she herself is a PACT Child Witness Support Volunteer and works in the Gold Coast area.

Our Child Witness Support Volunteers

Our Child Witness Support Volunteers are truly the lifeblood of PACT. Coming from various backgrounds and walks of life, the traits our volunteers share is compassion, resilience and the skillsets to build rapport with a child victim or witness to support them throughout their courtroom journey.

Requiring bucket loads of dedication to meet the emotional and time-heavy demands of the role, our Child Witness Support Volunteers are truly incredible. And since the process from initial arrest to trial can take up to two years and have unexpected delays along the way, our volunteers dedicate a significant amount of time providing impartial knowledge and support to child witnesses, ensuring they and other vulnerable young people have the ability to give their best evidence and move forward with strength and hope for the future.
