The roles of a pilot depends first of all whether they are deployed or at home.
While at home (and not on exercise) a pilot will spend usually only a little bit of time flying compared to fulfilling secondary duties. These duties will be assigned according to your level of seniority. Junior officers will usually be tasked with more squadron-based roles. These include keeping the maps up to date, ensuring everybody's log books are correct, being a
PR point of contact for the squadron, being a family liason officer for those members that are deployed etc etc. Any day to day jobs you can think of to keep a squadron running have to be done by somebody.
There are also a raft of other jobs that involve keeping the base your stationed at running day to day, and it is likely you could pick up some of those responsibilities as well.
While on exercise or a deployment, pilots will spend the majority of time either planning or flying - completing the job they've trained to do.
As you become more senior through your career, the jobs you're assigned will become more complex and you will bare more responsibility.
To sum it up, the ADF is like any other organisation really - junior officers (managers) tend to be more concerned with day to day operations, and senior officers (managers) tend to be more concerned with the medium to long term strategic planning.
