Discussion of snorkels or now snorkels is a personal preference and can get pretty strong support on either side. Location of the dive tends to dictate to me if I carry one. Mostly I don't. I find they pull against my mask and make it leak. Perhaps the shape of my mask Some places here REQUIRE a snorkel (Queensland) be carried. We have the fold-able ones to put in our BCD pockets for that purpose..
A high percentage of our diving is shore diving. We tend to lay on our backs on our back inflates and chat as we fin our to the point we want to drop down. We tend to stay underwater until we get to the exit point. If necessary we can surface and swim back in the way we started but we seldom do it that way after all you can see more stuff underwater. Lots of weed and kelp to get tangled in so just not worth bothering with for most of our diving.
The requirement in QLD is to carry a snorkel when on a dive charter, not dive with one or at least its enforced that way.
