Australia does not have a president. The government is run by a Prime Minister. The Prime Minister is elected for a maximum of three years per term, but there is no limit to how many consecutive terms they can be elected to office.
The French Prime Minister has no defined length for his stay in office. The President is elected for five years and picks the Prime Minister within the parliamentary majority. The Prime Minister has to answer to parliament which can ask for him to be removed. In French politics, it is common for the Prime Minister to protect the popularity of the president by taking responsibility of unpopular policies, and afterwards offer his resignation to the President. (The office of Prime Minister is often compared to that of a lightning rod.) Some Prime ministers stayed very few months in offices, others for many years.
