simple veggie garden fence

I need to fence my veg garden, predominantly against rabbit (and puppy...) pressure. I want it to be nice to look at, but also rigid and ideally, simple to install. I guess this could be split into a few questions:

My veg garden is in an unusual, previously landscaped part of the garden. It is not square - there are curves, slight changes in direction - see below images. Assuming I ignore curves and aim for straight lines there are in total 7 sides, ranging from 4 to 12 meters in length and not a right angle to be found. It will have 3 gates, with maybe another to be added at a later date.

What sort of distance from the edges should I be setting the posts? The garden, again detailed below, is raised on two sides by a dry stone terrace wall and flanked on another by the driveway. Accordingly, getting as close as I can to them is preferred - I am not cutting into any other gardening area on these 3 sides, but do not want to undermine what's here. I want to plant medicinal flowers and herbs along the fence line too, so the fence will be set in or at the edge of a bed. Should I be turning the sod to soil before installing the fence or after?

I'm considering either posts with rabbit-proof mesh fence running between or that plus hazel pickets - available very easily in the UK in this form:



In doing this though, I'm wondering if I can get away with just posts and wire (or that and pickets as well), without needing to worry about bracing posts or any other structural aspects? I don't want the mesh to sag, but does that really mean tension wires, braces and alike?

I'm looking at pictures of what seem to be very simple fences, but are the corners and changes in direction actually reinforced and complicated?

Maybe these are silly questions but in total its about 50 meters of fence. Appreciate the insights of anyone who has done this before - I'm trying not to spend a whole bunch of money I do not have on tools or materials I may not need.

I like t-posts and wire because you see through it easily yet it is sturdy.  I bought a post pounder at my farm store for around $30 and the t-posts come in several heights, all requiring to be put into the ground at least 12 inches. This would be a little too much for your beautiful garden maybe.  I like wire, whether it is poultry fencing or woven or welded, but the size of the holes depends on what needs to stay out.  I also found that if you only need to fence out bunnies, you can use the shorter wire which saves money and is easier to make tight than the taller types.  One think that I use on a more temporary basis is plastic chicken fencing in black, which surprisingly "disappears" when you look at if from a distance.  A puppy may chew on plastic, but the bunnies here don't.  

Recently I found green chicken wire and small metal posts that can be pushed into the ground by hand or with a hammer. They were more expensive than t-posts but can be used and re-used and pulled up fairly easily.  I used these to cage my young trees for the winter.  

I love your plan for this area!  Very nice!
