I would like to know what Commonwealth Government Securities are as I have a variety of definitions which all confuse me! I would also like to know their role in the Reserve Bank market operations.
Have you looked on the RBA site
On the side there are a list of choices which should help you out, domestic market operations should cover a lot of it
Government Securities or Govt. Bonds/Notes are issued by the RBA to meet funding needs
Last few years since Libs came in, they government debt has been reduced and there is not a lot of choice in the govt. debt market, so investors have moved into state govt and corporate debt
