hi, depending what you're after, i've found ebay to be great. you can buy things that are second hand or brand new at a fraction of the price...and you dont have to leave home.
also, theres a website called the bub hub. it's www.bubhub.com.au
The Bub Hub is an online, fully searchable, directory of local pregnancy and parenting information, shops and services. it's a really good site, check it out
My favorite site is www.usedbabyproducts.com.au , new fast growing platform for parents wanting to sell or buy baby things. They have promoted my ads on the facebook as well. Its super quick and free, less effort than outdoor markets, and reaches more people , that's for sure. Try it! It's very easy. grin
I have ordered from www.babyshop.com.au, www.limetreekids.com.au and www.cherubbaby.com.au and have found all three of these sites to be easy to navigate.
I have found that they offer some good products and the prices don't seem to be too high.
I have also found that facebook has been a great avenue to find nice little Australian owned stores.
If anyone else knows of any more Australian Brands I would love to check them out smile
