Received an email from Telstra Bigpond as follows the other day:

“Telstra realises that there has been a delay in responding to your enquiry and we would like to extend our apologies. Your email has now been received by our department and we have included a response to your email below.

If you would like to supply us with the phone number, including the STD area code, that you wish to have BigPond Broadband ADSL connected to, and address, we will be able to advise of ADSL availability on this line.
Yours sincerely,
Rick Palma
On behalf of Justin Milne

I am waiting to see if anything positive comes of this, will continue to note progress here.
