A fatigued Leisel Jones was able to muster her trademark finishing burst to win the women's 100m breaststroke final at the Australian short-course swimming championships in Melbourne on Wednesday night, but missed the world record.

Jones hoped to match the feats of her training partner Libby Lenton, who has twice smashed the world record in the 100m freestyle, but was just off the pace.

The 19-year-old Queenslander, who last week won the 100m breaststroke and broke the world record winning the 200m at the long-course world championships in Montreal, clocked 1:05.35, outside American Tara Kirk's record of 1:04.79.

Short-course specialist and winner of the 50m event here, Brooke Hanson, led at the three-quarter mark, with Jones powering home to take gold.

Hanson touched the wall in 1:05.48 while Jade Edmistone, who won the 50m setting a world record in Montreal, finished third in 1:06.66.

Jones, the Commonwealth record-holder in the event, said she was mentally fatigued after Montreal and missing her family.

While this event doubles as trials for the world short-course championships in Shanghai next April, Jones didn't plan to compete as it followed the Commonwealth Games here in March and admitted she lacked some motivation.

"It's a bit hard to race when you don't have many goals ... I don't want to swim short-course so it's a bit tough to swim with no real mission," Jones said.

She was disappointed she didn't match the feats of Lenton, whom she described as "inspiring".

"I'm so proud of her to come off eight days of hard work and Duel in the Pool and then to still come out and break world records twice.
