Hi Shaylee23
Sounds like a great adventure -- welcome to bushwalk.com
I found that the shops along the way are great for the meal whilst you are there (EG I have hade both breakfast and lunch at Somersby Store on different trips). There are basic supplies at Somersby and Yarramalong.
I think you will find it easier todo a couple of food drops before you set off, Cache the food somewhere you will find it again -- but that will be safe from animals and curious people.
You can still plan on stopping at the cafe's for lunch or an ice cream.
Aim to keep your meals simple but still yummy -- you can carry 12 days of food in a pack -- but I would do a couple of food drops with a few treats to make the walking a bit more enjoyable.
Hope that helps.
Happy walking
Matt
