WWF-Australia funds species and habitat conservation and runs a plastic-pollution programme (state single-use scorecards, Plastic Free July partnership, ReefCycle). It states that 74 per cent of spending goes to programmes and publishes an annual report (wwf.org.au/annual-report-2025).
It is a registered charity (Australian Company Number 001 594 074) and says donations over $2 are tax-deductible. Honest caveat: plastics is one programme among many, so a general gift will not go only to plastics; ask about directed giving if that matters to you. World Wide Fund for Nature (WWF) International's donate page blocked our check, so we list the Australian entity only.
