Grow Rich,i'm still in my negative mood regarding penn.Penn suggests nbn margins are trending towards 'zero'..Again can u think of a worse phrase for a co to suggest ie zero margin?.imaginary black hole,tpg mini mouse mobile threat.
These are the phrases /statements  the market remembers.
To be honest i haven't looked at tls's nbn margin trend,by memory tls pays approx $40 plus to access nbn sells $60 ?,also the larger the telco customer base the more competitive advantage that telco has.
I believe tls has introduced new nbn plans,2 of them,one i might change to and save $5 per month ie 50gb data,unlimited local/national calls and free calls to australian mobiles for $70 per month,plse check my details 
I would like to know if tpg has mentioned nbn margin trending to 'zero'.?Kitty,do u remember if teoh has used the word 'zero' nbn margin in his presentations,just doesn't sound like teoh,but yep it sounds like a penn comment..
ps this is a question as i don't follow financials in detail,but is penn also referring to the 'low cost' belong re sell  business when penn suggests 'zero' margin?lol how to stuff a sp use the term 'zero' margin.
