You'd pay $40 for a slab of Cascade Premium or Boags Premium... can get boags draught for $30 sometimes on special.
Carlton is normally under $35, sometimes $30
VB, no idea... tastes like piss anyway!
Carlton Cold, right on $30 most of the time
Extra Dry can normally be had for $30 as well
Corona, can honestly say I have NEVER had one. Don't want to either.
EDIT- Coopers Sparking Ale is my current fav, low $40's a slab. A fantastic beer and 1.7 standards as well, so go to smash a few before heading out
