So one easy way to make a raised bed is simply to buy some straw bales. The walls of the bed only need to be bale height, and maybe a layer of top soil over the top.
Eventually what happens is the that bale breaks down. and you keep adding layers of mulch and compost. Its also a great idea to put your compost bin in the middle of the bed, so as it breaks down, its feeding the soil directly in the bed (because why do you want to make extra work for yourself, shovelling compost onto beds?!?). You can do the same with worm farm - in fact you buy some worm farm kits from Bunnings that you bury directly into the ground, and then you feed your green and brown waste directly into it - the worms feed off it, and the nutrient from their castings is directly in the soil, ready for your veggies' roots to take up.
There's plenty of stuff on the net for this sort of thing - the idea is to make gardening as effortless as possible.
