Shikar - walk before run! You might do well to look at the CPL syllabus first before ATPL.
If you are going to study in Australia, there is an excellent initial guide to aviation called the VFR handbook that captures the essence of the sorts of things you need to know to achieve some degree of excellence in the procedural aspects of flying - the laws are all about safety so theres lot of aviation knowledge embedded in them.
It can be downloaded on the Australian CASA website
When you start studying make your learning systematic and not just the minimum standard.
good luck!
