I have just got into the collection house (last week and today) with the key strategic reason being the level of household debt in Australia. Interest rates will rise over time and I shudder to think what this will do for the ability of a lot of Australians to make repayments. A couple of more links below helps to also set the scene.
I also believe if management are being honest (ie have brought out all the dirty washing) then the stock has been oversold. In addition I like the fact they are not prepared to overspend to acquire debt to be collected.
