Explanation

Sierra Leone issued the first self-adhesive stamps in 1964, though they were experimental and faced technical issues. Tonga issued self-adhesives in 1963 but they were not technically stamps - they were embossed labels. Australia's first national self-adhesive issue came much later in the 1990s.
