There's no such thing as unlimited residential internet in Australia.
Not for $59.99 anyway - and from what I found, it is $79.99 with TPG, as you have to bundle your home phone with them. Also note the ~Limited coverage availability at selected ADSL2+ with Home Phone enabled exchange areas. Which would relate to the fact that they have to be exchanges that TPG owns, which you'll find is predominantly exclusive to Sydney (http://www.tpg.com.au/maps/).
Even with all of this, TPG is notorious for having poor service and high contention.
