KEY WEST, Fla. (AP) -- An Australian woman is getting ready to swim from Cuba to Florida.
Endurance swimmer Chloe McCardel has a practice swim scheduled Sunday in the waters off Key West. Her attempt at swimming across the Florida Straits from Cuba to the Keys without a shark cage is set for June.
She's the latest swimmer to try the difficult crossing.
American Diana Nyad has tried four times: once in 1978 with a shark cage, and three times in the last two years without it. After jellyfish thwarted her most recent attempt, in August, Nyad all but ruled out a fifth try.
Strong currents forced Australian Penny Palfrey to abandon her attempt last July.
One Australian has successfully finished the swim. Susie Maroney did it in 1997 with a shark cage.
