How much time do I need to give? One of the great things about volunteering for Sands is our flexibility. Because our phone support services operate 24 hours a day our volunteer parent supporters can sign on for wide range of shifts across the week – day or night - through our virtual volunteer roster. For support-based roles we do ask a minimum commitment of one 8-hour shift per fortnight. We do offer other once-off or short-term roles that require no ongoing time commitment.
