"We are glad that Australia has decided to open its first so-called pop-up embassy in Tallinn, which will undoubtedly increase Australia's visibility in Estonia as well as our region more broadly," Mikser said according to a ministry press release.

"An ambassador beginning work at the pop-up embassy will introduce new opportunities to the already constructive and close cooperation between our two countries," he added.

According to the Estonian minister, the experimental pop-up format for an embassy may end up leading to pilot projects for other countries as well. "Let's hope that Australia's positive example in its innovative pop-up embassy will encourage other countries to develop similar forms of cooperation in Estonia," he said.

A pop-up embassy is a diplomatic mission in which the ambassador does not work daily, but rather is on site as required.
