Hi Prova, you shouldn't have any problems seeing it in Canberra. I can see it from the middle of Melbourne.
1. You have to start from Deneb Kaitos, a.k.a. Beta Ceti - it should be quite bright and easily naked eye.
2. When you have that star in your viewfinder, move the scope south a little bit until you see three stars in the shape of a triangle - quite bright, around magnitude 5.
3. From there, nudge it south a bit more and you'll see 4 stars in the shape of a lop-sided rectangle, not quite as bright as the triangle. If you can get here, you're very close to NGC 253.
4. In your viewfinder, look for a faint slash of misty light, about 1 degree away from the rectangle of stars. That's the galaxy.
It should look good in your scope. You'll see a faint triangle of magnitude 9 or 10 stars, with the galaxy splashed right through it. There is also a nice globular cluster nearby - NGC288 - some scopes can fit them both into the same eyepiece field of view.
Good luck - post your results!
