I wanted to research them, that's why I was asking the question ! I have no particular interest in buying them (at this moment but who knows, maybe in 5 years I might).
It's interesting, ask a question but get no answers to the question asked
Aside from the bit of very general info from MR that I knew already and the specific link from auric (thank you).
eg WHERE do you buy them, HOW (and WHERE) do you trade them, WHAT rate.. Then perhaps more questions afterwards, like if they are not offering a decent interest rate above bank deposit rates where the hell is the incentive, the bank deposit are currently gov't guaranteed, or perhaps buy say, ANZ pref shares that pay 2% above the 90 day bank rate etc etc
If I ever did buy them it wouldn't be through a non listed fund, I would want direct investment. I had heard I needed sums of $500,000 or so to buy bonds directly for example but from that link it appears that info was incorrect.
I was asking questions and then hopefully more questions as I gained some understanding
