Hawkins received an elaborate Mikimoto pearl encrusted crown, worth $250,000 as well as an extensive prize package. Hawkins was the first blonde haired woman to win the title since Angela Visser of the Netherlands in 1989.
As Miss Universe, Hawkins represented the Miss Universe Organization. Her "sister" 2004 titleholders were Shelley Hennig (Miss Teen USA, of Louisiana) and Shandi Finnessey (Miss USA, of Missouri). During her reign, Hawkins travelled to Korea, The Bahamas, Brazil, Czech Republic, Germany, Greece, Singapore, Indonesia, Canada, Trinidad and Tobago, Cuba, India, Ecuador, Mexico, Puerto Rico, had multiple trips to Thailand, the host of Miss Universe 2005, and her home country of Australia. As part of her year-long reign as Miss Universe, she resided in New York City in a riverside apartment provided by the Miss Universe Organization. Also during her reign as Miss Universe, Hawkins stated that her wish was to continue modelling and become a television presenter.
Shortly after being crowned Miss Universe in 2004, Hawkins created news during a fashion show at Westfield Miranda, an Australian shopping centre, when she tripped on the hem of her dress, which fell to the floor. Hawkins was left scantily clad in her red g-string in front of a surprised crowd. Hawkins later apologized, laughingly adding she "wished she wore better underwear". The incident received the dubious distinction of being named "The most embarrassing moment ever shown on Australian television" by Australia's Nine Network. The "Wardrobe malfunction" was widely circulated through news outlets and according to Google, caused a sharp increase in internet searches for "Jennifer Hawkins".
Hawkins served as a judge for the Miss Universe 2008 finals in Vietnam.
