Hello Paul
I imagine that if Telstra had ports available, they would be "selling" them.
Only Telstra would know what their situation is, and a third party website would not have this information.
I can't offer you any other information as I am a customer....I am not a Telstra employee
You could speak with Telstra 24/7 Live Chat https://livechat.telstra.com/TCOM:Crowdsupport:Consumer
Thanks
