An Australian man drowned in Hawaii on Thursday, the state's third tourist death in as many days , highlighting an ongoing safety issue in the islands.

On average, nearly one tourist dies a week in Hawaii , according to a special report by Honolulu Civil Beat, typically while engaged in common vacation activities such as swimming, snorkeling and hiking. Many more suffer serious injuries, including spinal cord damage.

Critics say the state doesn't do enough to warn its 8 million annual visitors of inherent dangers, especially those involving water. All three of this week's deaths appear to be water-related.
