G'day C501. Welcome.
That's a big question you ask.
What type of viewing do you want to do? Lunar/Planetary? Deep Sky? What kind of budget? Is transportability an issue? Will you want to dabble in Astrophotography? Do you want to track the Stars? Do you want GoTo? etc etc.
You will have to answer these questions first so we can guide you in the right direction, as every Telescope has a different use
