Hi Jimmy,
I believe "Australian Backyard Astronomy" is aimed at a young audience, probably not what you are after.
"Astronomy 2015 Australia" is a yearly publication with a lot of very useful information for astronomers of all experience levels. Not "step by step guidance" for beginners per se, but it is a very useful resource with month-by-month charts and things to watch for in 2015.
The Pocket Sky Atlas (from Sky and Telescope) that Wayne mentioned is a very useful star atlas and well worth buying to have by your scope when observing.
If you are looking for a step-by-step book for beginners, the venerable "The Amateur Astronomer" (12th Ed) by Patrick Moore is worth a read, as is "A guide to the night sky" (Revised Edition) by Robert Burham et al. You could probably get copies of these from your local library to read through and get you started. Another oldy but a goody is "The Southern Sky" by David Reidy and Ken Wallace. Out of print, but check your local library. (These 3 are all a bit out-of-date in terms of latest equipment, which is why I would suggest the library.)
All the best,
Dean
