The Australian beauty rocks a long-sleeved crop top and bikini bottoms on the cover and talks staying happy through those challenging times.

"Happiness is a choice we make. You can wake up and say, 'Oh, I can't believe it's so cold,' or you can say, 'Oh, wow, this is a great opportunity for me to try out my new sweater.' No one can be consistently positive, but why not make the choice that makes you feel better rather than the one that drags you down?" the 30-year-old tells the magazine.
