I think that there are several changes that need to be made in relation to the way Governments run in Australia and the way that they interact with one another across state lines, the following things should be nationalised,
1, All the State Police Forces should be merged to the Federal Police.
2, All Prisions should be run by one central body.
3, National Road Rules should be across all of Australia. Motor Transport in general should be federally run.
4, One education system - HSC for all students.
5, Water Managment of all resevoirs and infrastructure should be centrally run.
6, Public Transport should be nationalised, Tickets should be the same price across Australia on the smart card scheme and should work in any network.
7, All hospitals should be run by Medicare themselves.
It seems to me that we over replicate and make massive amounts of red tape to do anything. If someone from S.A is charged with an offence in W.A, why should the SA police have to apply to the courts in WA to extradite that person? What a phenominal waste of resources, yet one that is replicated over and over again in what I have posted above and plus no doubt various other things that could be made examples of!
