Low on the horizon from Sydney
These clear the horizon but stay low, so trees and buildings may hide them: Lyra (~19°, northern) · Leo (~15°, north-western) · Cygnus (~11°, northern) · Pegasus (~8°, north-eastern).
Out of reach from Sydney
At Sydney's latitude these never climb above the horizon, so you can't see them from here at any time of year: Canis Major, Ursa Major, Andromeda, Cassiopeia, Gemini, Orion, Perseus, Taurus. To catch them, you'd need to travel toward the Northern Hemisphere.
