A few of the bottles I stocked up on were in the $20-$25 range for 650 ml and that was in Victoria where the beer is markedly cheaper. Not sure what it would have cost here if it was available.
Unlike wine, however, there appears to be a real top end to where beer prices can go. The best beer doesn't seem to get much more expensive than this.
Reminds me of the scene in Hall Pass where 3 shots of tequila was $57.
