Informal volunteering has a long tradition in Philippine culture. Recent developments in formal volunteering have led to Filipino volunteers and volunteer organisations becoming engaged in diverse forms of service as a strategy for achieving personal, organisational and national development goals. The last decade has seen a rise in opportunities for both international and in-country volunteer service for Filipinos. Given their common goals of cultural understanding, empowerment and poverty alleviation, this article argues for international volunteer service as a twin programme of in-country volunteer service. Particular reference is made to the cycle of national volunteering which incorporates the interactive impact of returning international volunteers and in-country volunteers on volunteering and development work in the Philippines. It is proposed that this twinning programme be bridged by the VOICE Network, a Filipino-led, Philippine-based multisector national network of primary volunteer organisations.
