Hi TGS and welcome!
The Silvia and Rocky combo is a great place to start and is the setup of choice for many CSers. Used well, you will get a brilliant result.
You will need:[*]Machine and grinder[*]Tamper 58mm (get a good one if you possibly can)[*]Coffee[*]Jug/s[*]Backwash detergent and blind filter
Other deisirbles/optionals[*]Knock tube[*]Tamp mat[*]Training- if required[*]Thermometer if you must- I am not crazy about them as you need a really good one if you want accuracy[*]Deep double basket
The Silvia and Rocky are pretty scarce in Melbourne but I am unsure as to the situation elsewhere in Australia. We have managed to get a few today: http://coffeesnobs.com.au/YaBB.pl?num=1163933911/5#5 Nearly had to sell my soul to get them! ::)
Good luck with your shopping ;)
