Hi there, why not start your own store?
7 Food excursions that are currently being used by teachers of food technology in Australia.
This word document lists excursions in Sydney Port Stephens and Melbourne.
The hyperlinks link to the registration for each excursion.
I have taken my group to the Easter Show one in the past and my colleagues gave me the rest of the list that they have used.
I am in no way affiliated with any of the groups. These are just the popular ones. Enjoy
