Julian Rocks – False Trench and Hugo’s Trench
The diving in False Trench and Hugo’s Trench is quite different to the rest of Julian Rocks. The two trenches are canyons that cut deep into the island and make for very interesting bottom contours. The further you swim into the trenches, the narrower the canyons get. There are lots of cracks in the rock big enough for divers to get through one at a time which makes for a very interesting dive. The trenches are well known for their abundance in colourful nudibranchs. When the current is running, the trenches are generally jam-packed with all kinds of fish life from huge Kingfish, Jewfish and Trevally to Queensland Gropers and Black Cods. The maximum depth in the trenches is about 17 metres.
