Where you buy these things will depend on where in Australia you live (assuming you live in Oz). It may also depend on your consumption habits and the quantities you would wish to buy. I find the organic product selection is getting better all the time at my local supermarket - but the small quantities sometimes make it uneconomical to buy things like flour or coffee - which we have come to have more of in our diet.
There are also many organic and natural supermarkets popping up in urban areas. If you live outside those areas perhaps you can buy co-operatively with likeminded friends.
Conduct a google search using key words like organic grocery tea and your town/region and see what comes up?
