Hi Darren,
What programming language and libraries are you using? I'd suggest to use Python and the
Skyfield library. After that calculating everything is a piece of cake and you can easily do timezone conversions. I'm using Skyfield all the time and it's fantastic.
Speaking about Venus - at 6:30pm in Sydney it should be at ~300 deg (West-North-West). Or alternatively -60 off North, but azimuth goes from North through East (90) to South (180) and then to West (270), so saying "due west at 62 deg" technically it's not correct.
