Internet good plan in australia?

[bathuu]

Hi all, i've just arrived in Australia, i need to set internet in my home now. Place that where i'm staying is doesnot have landline which originally i wanted go with ADSL internet connection. I'm a type of person who downloads a lot of stuff from internet so as much as bandwidht i can get is important to me than its fast download speed.
Is there any cheap plan ($40-50) that offer around 20-30GB monthly limit and 512-1024kb/s download speed without use of landline.
Cheers all

By the way i live in a Brisbane suburb

Check out if EVDO works in your area. Small device, fits in USB 2 port, great speed in 3G coverage areas. Works slower in 2G covered areas. (wireless). Please do a Google search for EVDO. My answer to you comes via EVDO at my end...
