Welcome to a new addiction and a costly one at that but a real fun hobby.New directions is quite expensive for supplies .I am a fan of
http://www.aussiesoapsupplies.com.au/ for probably the best bases(Brambleberries) in Australia not cheap but the best and wonderful service too.They also stock Brambleberries fragrances etc and for a small deposit will order special things you want from Brambleberries you have to wait for the next shipment to come in from the States but if you really want something special that is the way to go,freight is a killer from Brambleberries US if you do it on your own.
Another fragrance supplier is
http://bigtreesupplies.com.au/ Karen is a dream to order from such fast and efficient service ,she also stocks lots of different moulds at slightly cheaper prices than Aussiesoapsupplies.She also has micas and colourings as well.Great site to grab a coffee and just go through all her fragrances she runs reviews on her fragrances so that can be a help if you are just starting out.
My other fragrance supplier is
http://www.exurocandles.com.au/ they stock fragrances for both candles and soap so make sure you read each blurb so you get soap safe fragrance.The freight is great $4.35 for as many fragrances as you want which saves a bit.
Hope this helps
