Dynaudios are terrific, but do give the B&W 805's a shot and decide for yourself. In that general, high-line, monitor/bookshelf price range, you may also wish to consider Revel M22's (my favorite), and similar offerings from Focal, Monitor (Golds/Platinums), Aerial, Joseph, Totem, DALI, and PSB among others, if they are available (can't speak for Australia -- sorry!).
If you cannot test other speakers, Dynaudio is certainly a safe enough bet for terrific sound.
