Australian Parliament Operation

I love Australia, and have been truly blessed to have been born here more than 8 decades ago.

I fully appreciate our constitutional monarchical form of government, and the way our national parliament is elected, including the original purpose of giving each state, regardless of its population, the same number of senators.

However I have reservations about how ministers of the Crown are appointed and perform their duties.

Firstly, I have never understood how the Senate, as a House of Review, could possibly contain ministers, whose decisions and performance should continually be under review, by the same body that they belong to.
Maybe, Senate Estimates does this job, but possibly doesn't cover more aspects of a minister's or department's performance beyond financial ones.

Secondly, the fact that a minister who has the responsibility to represent and promote Australia's interests above all others, also has the responsibility to represent and promote the interests of his/her electorate. And because of the possible composition of a minister's electorate this may cause a conflict which the current system seems unable to avoid. (Jason Claire and Tony Burke seem to be perfect examples of this conflict at the present time.)

Are any readers aware of any discussion or websites or publications suggesting possible tweaks that could be applied to our current democratic system of government that could ease/remove these conflicts without losing the advantages our current system gives us.

Thanks. Blessings, Barry
