Low on the horizon from Sydney
These clear the horizon but stay low, so trees and buildings may hide them: Lyra (~19°, northern) · Carina (~17°, south-western) · Cygnus (~14°, northern) · Andromeda (~13°, north-eastern) · Leo (~3°, western).
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: Taurus, Cassiopeia, Orion, Perseus, Canis Major, Ursa Major, Gemini. To catch them, you'd need to travel toward the Northern Hemisphere.
