I'd strongly disagree with the aggressive behaviour accusation - jungles are not bad tempered snakes, in fact quite the opposite. Hatchlings and juveniles can be quite wirey and snappy, but quickly calm down with regular handling, and become a nice species to own.
True jungles only get to around 6ft in length, and so are much smaller than their cousins the coastal, but often the jungles being sold can be cross-breeds and therefore can grow larger and need more space.
We own Monty, who we believe to be a coastal x jungle,. he has the markings and colouration of a jungle but is the size of a coastal. Apart from that we are not blessed to own any true jungles yet,. they are quite hard to get hold of, and quite expensive. We know some people with jungles, and they are very beautiful snakes.
Similar to these guys are the irian jayas, have you looked into them Jacky? - we have a yearling pair of irians, who again top out at about 5 or 6ft and are a much more slender species. Again hatchlings can be snappy but they quickly calm down with regular handling and do well in an enclosure of 3ft x 2ft for one adult.
The difference with the morelias is that jungles are arboreal snakes, and need more height than the others, whereas coastals and irians will climb if given the opportunity but it is not so detrimental to their health if they can't climb. Next issue in Reptile Care (Nov) we are featuring articles on the jungle and the irian jayas, I can send you a copy if you like, or I can email you the articles over so you can read a bit more about them?
Here are some pics of our morelias - 1] Monty, our coastal x jungle.
2 & 3] Atlas and Inanna, our irian jayas, as hatchlings.
4 & 5] Atlas more recently
6 &7 ] Inanna more recently - Note how much their colour has changed in a year or so!
