I'd put the sextant, map, and shark powder last. The first two are almost useless unless you plan on building a raft and trying to find civilization, and chances are you don't know how to use the sextant anyway. The shark powder is even more useless. As far as I know a transistor radio refers to a radio that can only receive, not transmit radio signals. If this is correct, then it's only possible use is to start fires, unless you have a degree in electrical engineering(and you probably wouldn't be able to make a working transmitter in the proper range and frequency anyway).

I'd put the chocolate bars lower on the list, other items on the list such as the fishing kit would be much more useful in the long run.

The army supplies probably contain some fishing items, but that depends on the kit, and the more fishing supplies the better. Since it's the only item on the list that probably contain matches or another firestarter, I agree with it's priority on the list. However I wouldn't say that it has all the essentials, or even close to that.

I'd put the 10 liters of fuel a bit higher on the list - 10 liters is a lot, and it can help start fires if used carefully, in addition to being used for signal fires. This is especially important with limited fire supplies and likely someone inexperienced with creating fires in the wilderness.
