We looked at Blindsonline.com.au but didn't use them, they do however have really good feedback on productreview.

Who did you end up using if anyone?

will be using these guys when the time comes, have had good communication with them

We ended up with shutters to most of the windows (originally was going to do blinds) and the few blinds we did get we got through the shutter guy as he lives in our estate & did a great price.

We used Blinds On The Net and were very happy.

At our old place we used Blinds Online for the following:
2 x double roller blinds (sheer and blockout)
3 x venetian blinds
1 x vertical blind

They took a little while to arrive (for the vertical) but they were all very straightforward to install. I'd recommend them, and once our house is built we will be going with them again. You can order samples of their products from the website too.
