Whilst contributions to thadocta's Australia-registered nonprofit are not charitably deductible in the USA, they are certainly for a worthy and good cause, good enough non-Australian members may be willing to contribute on behalf of a longstanding FT member who has contributed here himself to our travel knowledge. :-:
(US Internal Revenue Code Section 501 (c) (3) excerpt states, in part,
"Not Deductible As Charitable Contributions
Foreign organizations (except certain Canadian, Israeli, and Mexican charities."
Please note this is only applicable to U S contributors seeking tax-deductability for their contributions; check your own country's regulations for further information.)
