Also, margin squeeze is what I suspect happened to Vaya for two reasons:

1. How else did they end up with $50m in liabilities to Optus?
2. About a year back Vaya suddenly stung their entire customer base with a $20 'security deposit' which was ultimately deemed to be in contravention of the Telecommunications Consumer Protections (TCP) Code. http://www.zdnet.com/article/acma-finds-telcos-contravened-tcp-code-with-security-deposits/

Reading between the lines I'd say that that the latter was a pure cashflow grab as Optus kept squeezing Vaya.
