To get the number of politicians down and save money abolish the 800 local gov't and the 8000 local politicians that go with it.
Then redraw the state boundaries so they have better populations.. Abolish Tasmania put it back into Victoria, rejoin NT and South Australia into WA. So with 3 States we save on 24 Senators and 50 odd House of Reps. That should save 100 million a year.
What is fair in Tasmania with less that 500,000 people having say 10 senators while NSW has the same number. That is unrepresentative of the majority. Then there would be no greens and we could get on with developing the country.
The NT is the 3rd largest self governed juristiction in Australia and only has 4 representatives in Canberra, both houses combined. Representation through population size doesn't really work well in the NT. Due to this system I am in Lingiari but I live 50km out of Darwin and All my business is conducted in Darwin which is basically the electorate of Solomon. There is a shit load of people with the same issue as Darwin's rural area forms a significant part of the NT population as a percentage.
I would rather see political representation more a geographic representation than a population one. It would help MP (Moana Pasifika)'s be more in tune with the needs and issues of the electorate.
How can the member for Lingiari possibly represent both the people of the Red Center and outer Darwin including everything in between.
I don't think we need less representation but more productive representation.
Then there is economical representation. Head per capita, we are the second largest economy in Australia.
There is a push for statehood in the NT. Should they ever get it, I wonder where the added Senate representation will come from.
I don't think it helps when the capital cities of most of the states are not even close to being central in their juristictions.
