How close to Sydney are you, I'm thinking the original Cabela's store. It's nice when you are just getting started to be able to see, touch and select the stuff in person, that's how I was able to start. It may make a nice Saturday trip
Oops, There I go again, save to say it's been a while since I've been there. I stopped at the Sidney store in 1981 when it was the only store, I didn't know what it was until I got inside. I still say choose a good destination with a fly shop on the other end and make it a roadie. Call to check on hours and ask about the size of their inventory first. You can probably come up with some good prospects via Goggle.
It's Sidney, not the Australian Sydney. Only reason I know this is that I have lived In Sidney Nebraska for all of my life and have worked at Cabela's Distribution Company for quit some time lol. Have met the original Dick and Jim Cabela on many occasions and actually went to high school with some of their kids. There is a Cabela's in Omaha if you live close to there.
Any local shops are great - nice to see materials and talk to folks about them. Cabelas has some good stuff. If you have a Cabelas close to you, don't forget to check they tying stuff in their bargain basement online. You can have it shipped free to the store for pick-up. I've gotten some great deals there without paying extra for shipping.
Here are some websites I like: www.casterflyshop.com - a really great selection and FREE SHIPPING! I've had only good experiences with them.
I collect lots of materials that may or may not become flies in the future.
Halloween wigs, Christmas tinsel, packing foam, corks, fuse wire, lamp cord, rug hooking yarn.... road kill
I got boxes of the stuff and although I'll never use it all I use it enough of it that it's worth collecting and gets as much use as any store-bought material.
