Expedition Status

Welcome to the Operation Wallacea expedition status page. This page is intended for updated arrival information for each site. Please note that due to timezone differences, updates to this page may be delayed by a few hours, and we cannot give specific information regarding school groups or individuals.

We advise all the parents or loved ones of our expedition attendees that it is not unusual to have no contact with participants throughout their project. Most of our sites do not have phone signal, and those that do have intermittent signal typically have activity schedules that make it difficult to find the time to call home. No news is good news, and we will always get in touch with emergency contacts if something were to happen.

The UK Office operates 24/7 contact numbers during our season, you can find the numbers on the right. Outside of UK office hours (9am – 5:30pm Monday-Friday) we would ask that people only contact us if there is an emergency, in order to help us keep the line clear.

We are sometimes able to post updates of our expeditions on our social media, visit our biodiversity messaging page to see our most recent updates on instagram, TikTok, Facebook and Twitter

Summer 2026

Croatia: Expeditions Have Begun!

All students have arrived safely on site and are now beginning their surveys.

Over the coming weeks, students will be gaining valuable field experience while contributing to our ongoing conservation and research programme.

Our expeditions will run until 12 August 2026, providing nine weeks of data collection for our Summer 2026 season. New students and staff join the expedition each week, with official expedition dates running from Thursday to Wednesday.

This status page will be updated as soon as we receive reports from staff on site. Please be aware that communications can occasionally be delayed due to field conditions, but we will endeavour to share updates as promptly as possible.
