Himalayan cedar or deodar cedar are the common names of the
Cedrus deodara. I agree with Alpine concerning its growth.
Had a look at your Japanese white pine: really good material, but has been somewhat neglected. I wouldn't be surprised if it needed repotting. As it's not the right season for that, you could start by simply giving the tree regular doses of fertiliser and Seasol -- especially Seasol, as it's a lifesaver for neglected trees. Secondly, in your place I would start by removing the lowest branches on the left and right, and maybe the second ones as well, since they are underdeveloped. Then I would shorten all the new shoots. Don't cut them back completely to last year's needles, or the whole twig might die. White pines differ from the JBP in that respect. Read Kimura on the subject, in the Book
Pines of the Bonsai Masters Series, a book very worth having. See
http://www.stonelantern.com/Pine_Bonsai ... b1pine.htm Note that it is sold in Australia as well, by various bonsai nurseries. Anyway, with pruning and good care you should start to see some back budding, and healthy white pines are great back budders! I wouldn't do any further styling for now, leave the tree with its foliage to help it grow.
Some people might recommend slip-potting this tree into a larger pot until it can be properly repotted. I am hesitant on this, as I can't judge of the root system or the soil without seeing them, but I wouldn't disagree with other forum members who have experience on the subject.
