(Very) Small Bushwalking Shoes / Boots - Australian Vendors?

Hi there.
I'm gently encouraging my partner to do some bushwalking with me. One hurdle though is that she is very small in stature. Consequently, her feet are very small as well. We recently visited a couple of hiking supply / shoe shops in Brisbane, and her feet were way too small for any of the women's shoes they stocked, and the kid's shoes were limited in range and not really fit for purpose. She seems to be the equivalent of a US Women's size 4, or US Kid's size 2. Her foot length is about 20cm.
I have taken a look at the REI website, and can see they have an excellent range of children's bushwalking shoes and boots.
Are there any outlets with a similar range in Australia?
Many thanks.
