Welcome to the site Julie!
holy moly, you're jumping in at the deep end! Do you have any gear? It will be exspensive to get all the gear together, so i hope you really like camping because you wouldn't want to buy it all then hate it! It's usually best if you can go along with people that have all the gear and see what works and what doesn't for you.
For example, you want a tent, chairs, tables, lights, esky/fridge, tarps etc etc, it all adds up and before you know it you've spent thousands. Is that ok?
We could tell you what you need but i'd hate for you to go out and buy it all then really hate it because it rained and there were too many flies, too much noise etc etc.
This could be interesting!
