The Australian sun can be intense, even in cooler months. Bring plenty of water to stay hydrated, and use reef-safe sunscreen to protect your skin and the environment.

3. Be Mindful of Marine Life

While it’s exciting to encounter marine life, it’s essential to respect their space. Avoid feeding fish or touching any creatures you encounter, as this can disrupt their natural behaviors and habitats.
