To mark this historic and important milestone, the three postal administration – Singapore Post, Australia Post and New Zealand Post jointly issue a Tripartite Stamp issue with the theme Parliament House. This further strengthens and arms the excellent relationship of Singapore with Australia and New Zealand.

The theme, Parliament House is meaningful and interesting because Parliament House is important buildings of the country. To add on to the signicance of the Singapore-Australia-New Zealand Tripartite Joint Issue, this stamp series will be released on the 14 August 2015, on the rest day of World Stamp Exhibition 2015. It will be an issue that celebrates the extraordinary friendships forged between the three countries.
