Well, our daughter, who undertook "community service" as something semi-required by CDN Intl School - actually did it by helping out playing and semi-teaching young kids on Saturday afternoons at the church my spouse & daughter attends.
CrossRoads do lots of worthwhile work; it's near Gold Coast. Warehouse; office; cooking; equipment repair; packaging up clothes.
Refugee Council; teaching English; playing games with children; office work.
Amnesty International, World Wildlife Fund, aged care facilities,
What are your daughter's interests? Then google it.
When my grandson did the Silver AYP a couple of years back, he accumulated most hours at Crossroads and helping out in school - his community service record must be signed appropriately for validity.
