The several species of Casurina that grow around here all have much longer needles, usually 6" +, depending on species. They are almost all olive-green, drab coloring, even the new growth. Unless pruned up, they are branched to the ground and have a fairly formal Christmas tree shape. They tolerate a lot of wind, then the 'formal Christmas tree shape' becomes more windswept, but almost always maintains one main leader, then horizontal or somewhat hanging branches.
Melaleuca linariifolia has pale, peeling, papery bark (the classic Melaleuca bark which gives them their common name, Paperbark).

M. bracteata has darker, gray/brown, fissured bark, as do the trees posted above by Stephanie Choo.
