Fruit and veg

Ok I am sure this has come up before (sorry!) but we need some help. We are going to be building some raised beds for veggies and herbs and have some space for fruit trees and potted edibles.

We are in Sydney, the Hills District if it helps, so after some suggestions for best fruit and veg to grow for the climate.

If anyone had companion planting ideas as well for raised beds, that’d be so so helpful.

Thank you!
