ACF pressed the Federal Government to lead a campaign for a worldwide ban to whaling and for an end to whaling in Australian waters. Thirty thousand supporters responded to a television advertising campaign to 'Save the Whales'. In a 2004 speech to mark the 25-year anniversary of the end of this slaughter, former ACF president, Peter Garrett, described the ban on whaling – which came after examination of evidence from scientists and conservation groups that included the ACF and Project Jonah – as "a critical moment for...the many Australians who were beginning to attach a greater significance to the protection of our natural world".
