In the 2013 edition of Astronomy Australia (Wallace, Dawes, Northfield), available from Bintel online, there is a long list of deep sky objects (DSOs), their tyo\pe, constellation, and magnitude.
There are also specialist books on the southern sky, one of which is O'Mears's Deep Sky Compansion: Southern Gems which lists over 120 deep sky objects: clusters, galaxies, etc which can be seen from Australia.
However, as with all the DSOs, a dark sky really helps and significantly improves your chances of seeing them.
Now there are many software applications that give you exact co-ordinate locations (in either equatorial or Alt/Az locations) and these are often free or very low cost as downloads. They are available for PCs, Apple IOS and Android. Some are: Mobile Observatory, Skylight (which is usually given away free with small Celestrons'), and the Sky Safari group (3 apps, the last two of which are very powerful tools but cost some money to download. CHeck out Google Store etc for the apps.
There are also the old fashioned star charts which you can also buy from Bintel. Have a browse through their book section online, there is heaps of interesting stuff there.
Finally, while a 130mm will see many DSO, especially the brighter ones like Omega Centauri, 47 Tucanae, Centarus A (The Hamburger Galaxy), if you live in a major city it will be a real struggle to get down to the magnitude levels less than those of the brightest. If you take your scope to a really dark spot away from the cities you will see much more and learn the sky.
Best of luck.
