Answer 1

Piece by piece we’re seeing a clearer picture of the priorities of the new federal Turnbull government. Yesterday the Department of Prime Minister and Cabinet published the full administration arrangement ordwer for the machinery of government changes to match Prime Minister Malcolm Turnbull’s frontbench overhaul.

Three departments get new names to match their ministers’ titles:
Department of Agriculture becomes Department of Agriculture and Water Resources (DAWR).Department of Industry and Science becomes Department of Industry, Innovation and Science(DIIS).Department of Communications becomes Department of Communications and the Arts (DCA).

Answer 2

What were the new administrative arrangements during this period?

Answer. The new administrative arrangements during this period were:

Some important administrative posts were made hereditary means that sons succeeded father to these posts. 

Sometimes one person held many offices. For instances, besides being a maha-danda-nayaka, Harishena was Kumar-amatya which means an important minister, and a sandhi-vigrahika meaning minister of war and peace.

Important men probably had a greater say in local or city administration. These included nagara-shresthi or chief banker or merchant of the city, the sarthavaha or leader of the merchant caravans, the Prathama-kulika or the chief craftsman and the head of the Kayasthas or scribes.
