Timing. All timing has compromises. October-December has easier water availability, cooler and lower fire risk, but you may encounter residual snow drifts (more likely on a N-S routing than S-N), and some river crossings may be trickier. Jan-Mar is hotter, and some water sources may have dried up - serious blizzards are less likely (but still possible). You takes your choices.
Water. Read Chapman's guidebook carefully. He describes water sources as "reliable", "usually" and "sometimes available". In general, there is water available every 10-15 km, so unless it is a really hot day, you mostly only need to carry 2l with you. Certainly you should have the capacity to carry 5l (a bladder, collapsible bottle or wine cask are good for this) to carry into a dry campsite or hot day. The availability of water on the less reliable sources will depend very much on how spring rain there will be. The driest section is from Mt Speculation to Mt Hotham, although a number of rainwater tanks have been installed there, so water is actually pretty easy now.
Food drops. Start your planning with the resorts of Hotham and Thredbo (both have stores with somewhat limited availability, but you can post specialty items to yourself). Kiandra, Benambra-Corryong Rd and Mt Skene/Rumpff Saddle as the mid-points between the resorts gives you approx 110 km between drops all accessible with 2WD vehicles (although the Licola Rd is closed until October). Others go with a couple more drops, although accessibility is harder. I'd suggest working out your food per day, number of days and desired pack weight and let the answer fall out from that - those intending to do more side trips and/or fewer km per day will usually do more food drops. Rumpff/Skene is the only food drop where you might include water as well.
Comms. With the spread of ski resorts in Victoria, you will generally only be a day or two between higher peaks that have line-of-sight to a mobile base station, but no mobile coverage in the valleys. Things get patchy in NSW once beyond the main range (although some coverage near Kiandra/Mt Selwyn). Biggest blackspot is Kiandra-Orroral. So as long as you have an EPIRB/PLB for if things go wrong, sat phone not reqd as you can stay in reasonable contact with a 3G phone (esp. on the Telstra network). Anyone attempting the AAWT should have good navigation skills with paper maps and compass - the GPS in your phone is a good backup if you want to occaisonally confirm your position, or in a whiteout. If you intend to use GPS as your primary means of navigation, then a dedicated GPS unit may be a better option. If using the GPS in your phone, consider offline maps and also how you are going to keep your phone charged - GPS and screens are huge battery drains.
Pack weight. You should be aiming at 6-8 kg base weight (ie. excluding food, fuel and water), although lighter weights are possible with careful gear seelction. If you post a proposed gear list, there are plenty of people on these forums who will critique it (in a positive way).
Food. Getting in a balanced, adequate diet while staying lightweight and non-perishable can indeed be a challenge. Keeping it varied and appetising for 6 weeks is also important. You should be aiming at 3500-4000 calories per day, at around 700-800g pppd. Carbs are your body's preferred fuel source for intense exercise like climbing mountains, and protein is essential for muscle repair. However, protein and carbs are heavy at just 4 calories per gram, while fats are much denser at 9 calories per gram. So peanut butter, and adding some olive oil to dinner meals are common ways experienced long distance walkers add some lightweight calories. You don't need to use fancy (and expensive) freeze dried meals - I just use commercial rice and pasta mixes, and throw in some vegetables I have dried myself (diced and dried in the oven for 3-4 hours @ 60-70C) and some dried meat or chicken, or some sliced salami.
Training. You should be thinking about your walk program before the AAWT, and plan a number of 2-3 day walks in the leadup to your big trip to a. gain some experience (especially navigation), b. build fitness and c. test and tweak your gear and menu plans.
Chapman's AAWT Guidebook should be an early purchase, as it will help a lot with your planning.
