The disabled shooter said the Swiss Open was always a strong event, but would be even harder this year.

"It's always a strong field but this year will be particularly strong because of the Paralympics," Worsley said. "Anyone who wants to compete at the Paralympics will be there, so it's going to be very stiff competition."

"I really like the Swiss range and seem to go well there."

Worsley will be competing in the prone and standing disciplines and is hoping for a strong result to secure a spot in the Australian Paralympic squad to be announced in July.

The difference between the two events is that in the prone the shooter's elbows can be rested on a support, but cannot in the standing.

After competing in the Paralympics in Atlanta in 1996, Worsley finished sixth in the standing and ninth in the prone at the Sydney Games four years later.

The shooter scored his first perfect 600 game at the Swiss Open last year, before falling back to second place in the 10 shot final.

This time Worsley will be hoping to score another perfect score but also come away with the top position. "I'm hoping to do well because it's my last hope before the Paralympic team is announced."

While in Europe Worsley will also compete at the Hessenpokal tournament in Germany.

The shooter has been competing in the two European events since 1999 and said it was the perfect preparation for his Paralympic campaign.

Worsley said his training in the lead-up to the two tournament was as good as could be expected and will fly out for Switzerland on Tuesday.
