Hi acuyeskenso,
No every building has TPG FTTB, if you move house and that place has not TPG fibre, NBN or ADSL will be you only options.
You can move by contacting our customer service (they are a bit busy) or online, https://community.tpg.com.au/t5/Accounts-and-Billing/Moving-your-TPG-services/td-p/17838
Thanks
