The Australian supermodel, who got engaged to Jake Wall last year after a seven-year relationship, said that they are planning on celebrating with friends and family on March 19 in Sydney's Palm Beach.
Hawkins told the Herald Sun: "Jake and I are going up there for four days and then people will come up for the party on the Saturday.
"I have not got a dress yet. I am going to meet [designer] Toni [Maticevski] before I fly out. Being engaged is just cool - it is wonderful."
