1. What is a republic?What is a monarchy?How does the Cth-Constitution frame the Australian monarchy?

2. What is democracy?How does the Cth-Constitution frame the Australian democracy?

3. The author of the text (https://www.canberratimes.com.au/story/7633779/an-australian-republic-requires-a-new-constitution/) is critical about the electoral system in Australia as one central pillar of the democratic principle. What does the Cth-Constitution say about elections? Does the Cth-Constitution prescribe any particular electoral system? How did the High Court interpret the Cth-Constitution regarding elections?

4. What is a"single-member district electoral system"?The author (in https://www.canberratimes.com.au/story/7633779/an-australian-republic-requires-a-new-constitution/) comes across as rather critical in that regard and appears to favour a "proportional representation" electoral system instead. How does such a system differ from the "single-member district electoral system"? How does Australia's differing electoral systems in the House and the Senate support (or not) the arguments presented by the author for or against these two electoral systems?
