A book called a Missal contains the words and readings for the Mass. You can purchase one that just contains what you will need for the Sunday Mass, or you can get one that is suitable for Masses on all days. Missals are available at most Catholic bookshops.
There are other religious groups that either print or provide a digital version of the readings, for example, Word Among Us https://wau.org/meditations/
However, you might find the wording slightly different if they aren’t Australian sites/publications as not all countries use the same version of the Bible.
The Universalis app can be set to the Jerusalem Bible, the version used in Australian Masses http://www.universalis.com/
