Main thing pointing that high up is making sure your scope doesn't hit anything while imaging, as that tends to put the camera low on refractors,
The south celestial pole ( SCP ) or “the Pole” in Sydney is only around 34degrees in altitude
Not exactly “high”. In fact I would say most astrophotographers image above 35 degrees due to variations in atmospheric instability which affects your image quality and resolution , the severity of which depends on your image scale
