Multiple World and Olympic champion Sally Pearson will make her big event return at the upcoming IAAF Diamond League in Birmingham on June 30.

However, the 26-year-old will take part in Czech Republic meeting in Ostrava three days earlier.

The Australian has recovered from grade-one hamstring tear she suffered in the 4x100m race at Asian Grand Prix Athletic Championship last month.

With only eight weeks to the World Athletics Championships the Queenslander feared the worse but now she claims to be back in her training rhythm and eyes peak form for Moscow.

"My motivation, which I think is the key to optimal performance in training and competition, is at an all time high," posted Pearson on her blog.

Pearson hopes to repeat World Championship success in Moscow this season, in her favourite, 100 metres hurdles, event.

World discus champion from 2009, Dani Samuels will also make her comeback in Birmingham, after suffering a foot injury.

Following an unsuccessful competition at London Olympics 2012, Samuels stated she had learnt her mistakes.

"The lesson for me was that I needed to bring some variety back into my program and I have started to do that," she told reporters.

The priority for both of the Australian athletes is now to continue competing at top class level and once again, stand on the highest step of the podium at World Championships ahead of their event rivals.
