Sources of the PM's Powers

Head of Government
The PM is the top amongst equals in Australia, hence they acquire all the information before cabinet and shadow ministry. They are briefed from all the departments whereas Ministers are briefed from their department. The PM&C also provides info to both PM & Cabinet, which ensures that the PM is aware of all things happening.
Advisor to the Governor General
As an advisor to the GG the PM has the sole decision on the date of the next election. This can be highly advantageous as the PM might declare an election when his/her approval ratings are at a high, allowing them a high chance to win the next election. Section 28 limits this power of the PM as it sets a maximum date for the general election to be called. Section 57 also gives the power to the PM to request a double dissolution election, as per the criteria of the section is met.
Head of Cabinet
As the Head of the Cabinet the PM is able to dictate the agenda for cabinet meetings. This means that the PM’s agenda is the Govt’s agenda. Ministers are also allowed to discuss issues but are they are restricted by having the need to provide documents, benefits/costs & statements regarding human impact which narrows the scope of discussion

This allows the PM to withdraw support from MHR’s (within his/her party) who vote against the govt legislation, making it harder for them to run in the next election. Without party discipline, rogue party members may vote for whatever they want, hindering government business. These rogue members are dealt with the aspect of CMR, entails that ministers must support and defend the decisions of cabinet and the government, hence serving collectively.
