Welcome to the community,
Could you please send me a PM (private message) with your Full Name, CID (customer identication number) and your mobile phone number, so I can take a look at your service?
I was able to locate your account details.
I can confirm you're on the 12/1 NBN Plan.
Which translates to a Max download of 12 Mbps & an upload of 1 Mbps
the next plan is our 50/20
