OK, the setup APPEARS to be correct, in that the sidereal time (which is worked out from the geographical coordinates and the hours from GMT) showed the same value as that on the website
http://www.jgiesen.de/astro/astroJS/siderealClock/ when set for Sydney.
What is strange is that I was unable to align the scope using Antares (almost at azimuth) and Spica, using 2 star alignment. I got an alignment mismatch error even though both were spot in on my 6mm EP. Then I went to Jupiter, confirmed the coordinates, and it was then unable to find Antares accurately...
