I am extremely lucky that I've always had such a supportive family to allow me to adventure and spend time doing these kinds of things. I'm sorry to hear that! I know how much you have been wanting to dive and explore for yourself
Hi I'm from Colombia but I live in Australia as well. Definitely the reefs in Colombia, San Andres y Providencia Islands, Tayrona Natural Park and Malpelo.
Reef health-wise, I was very impressed by Cuaracao. Similar to your Cambodia experience it wasn't the most "fishy" experience, but the soft and hard corals were very healthy. My first ever dive was in Dahab in 2008, before getting certified in Jordan in 2013. As a primarily Carribean diver now I do miss the vibrancy and biodiversity of the Red Sea.
The Red Sea lives in my dreams! I cannot wait to go dive there again. I have never heard of the diving in Cuaracao. I'm so excited to add it to the list! 🌎
