Concertgoers have rubbished Whitney Houston's first Australian show with punters warned they would be better off skipping the concert and buying the album.

Houston sang off-key and was exhausted after just two songs when she performed her first show in Brisbane last night, write Nick Loader for AsiaCorrespondent.

The Houston Australian tour has been plagued with problems which led to the cancellation of the Perth show due to lack of ticket sales.

The comments from punters coming after the first show are littered with words like 'disappointed' and 'disgraceful' with one audience member calling it 'the worst concert I've ever seen in my life'.

The Houston ticket is not cheap. At $165, one Brisbane punter told CBS 'Houston couldn't entertain a dead rat'.
