A drift dive though the Dennison Canal
at Dunalley. This is a restricted
navigation channel so aproval form the
canal superintendant needs to be given.
Best done at slack high water( about
2hrs 15min after Hobart high water)
The best section is around the Bridge
with lost of soft corals and sponges.
Often large schools of fish pass
through.
Carefull planning is required and a
safety boat should be in attendance as
the current can exceed 15km/h.
