I got all my stuff from Springers. Some of their stuff is cheap compared to other places, but some stuff is expensive, but it's a good place to go and check out. You can browse stuff in the shop and talk to them about it, and get an idea of what you want, and you can then search other places for prices to compare.
They have a website: http://www.springers.com.au
The website is good as it has prices.
PS. Thanks Jo&Kev.
I ended up running the fridge through the solar regulator, but then found out that's no good because because the regulator can cause damage to accessories when it cuts in and out. And it's also no good to run the battery down to 10.5 as it damages the battery, sooo now i have set the cut out higher on the fridge and will have to rewire it so it's directly from the battery again. I think the battery is on it's way out as it was second hand when i put it in, so i'll get a new battery, one day
