Wow, what an opportunity! You say that online selling has not caught on--you are on the ground floor of something destined to be something big. You have little competition so this is your chance to be the first to corner the market with your products.
Study the US sites that are similar to yours. Learn what they do to market their products. Study what they have studied. Believe me, if you think Autralians are not on the internet, I can tell you are quite wrong. A great deal of traffic and sites in the children's area of interest pops up whenever I am looking for information.
Just be there when your community is looking for you.
Good luck and let us know how you are doing.
