Charity Begins at the Post Office
Like most Australians I support a rather long list of charities, because by their very nature, charities rarely generate sufficient money from commercial enterprises to carry out the very expensive activities which seek to make life infinitely more comfortable for those less fortunate members of our society.
Other charities exist to care for the welfare of both domestic and wild animals, and others to provide services for the community such as volunteer rural firefighters and lifesavers. These are equally as expensive to operate as is medical research into the whole range of human illnesses.
Australia Post, which of course is not a charity, derives substantial income from the postage paid for regular communication sent to a whole bunch of strangers by the vast majority of the charity organisations in our society.
I wish that the charities who have my address would treat it as top secret for their eyes only.
