you have to know both the ottawa charter and the jakarta declaration, they usually only test one each year and im fair sure they always test ottawa charter, but if it comes up you need to no it. sometimes they will ask a multiple choice q on jakarta declaration but most long responses are on ottawa charter.
a few years ago my teacher made a question up for the hsc and they said they would use it one day. it was: how does the jakarta declaration build on the ottawa charter?
its all about the new public health approach, just keep relating it all to that
