Found out that I needed a 12 month contract which would cost me $149 to break, he was unable to tell me why this was required or what costs it covered, or whether this would be reduced over the period of the contract (ie. a cancellation one day early would still cost me $149).
Also found out that I would need to purchase my own ADSL modem (and the only one for sale on the site was the Fritzbox for vdsl), the guy couldn't even recommend one. It appears this requirement isn't on the Snap website, as I didn't realise this until I talked to him.
These were enough to send me to telstraclear, with no contract and a free modem ($5 less per month, and 10 extra GB on their cable network).
Hope this helps.
