From what I have seen on Coz, about 60% of the people dive solo. They are frequently diving off of a boat and accompanied by a guide and at least one friend who is also diving solo, but nonetheless....
The advantage of solo diving by yourself is that you aren't under any delusion about who is going to save you if the proverbial dung hits the proverbial fan.
Nonetheless, one should not solo dive alone at least until he or she has a reasonable amount of experience and understands the skills and additional equipment that should be present, and should start in a familiar location under good conditions. If a diver thinks "solo diving" is dumb or unduly dangerous, then that diver should not do it all. The same could be said about caves, rebreathers and other types of diving.
So, to the OP, no you probably don't want to do this by yourself just yet and maybe ever. Find another person to hang around with you on shore dives this trip and if you want to dive by yourself later, look into the issue a bit more and get a bit more experience, and maybe borrow one of Dandy Don's pony tanks
