Stolen Olympic and Commonwealth Games medals belonging to Australian pole vaulter Tatiana Grigorieva have been found, Queensland police said today.

Grigorieva's sporting mementoes were stored in a safe stolen from a business premises at Tingalpa in Brisbane's east on July 18.

Police have recovered several items following the execution of a search warrant in the Wynnum area, on Brisbane's bayside.

Grigorieva's Sydney Olympic silver medal and 2002 Manchester Commonwealth Games gold medal were among the items found.

Police said other sentimental items including medals and an Australian flag bearing autographs of the entire Australian 2000 Sydney Olympic Games team were yet to be recovered.

The Gold Coast based athlete, who has been competing in Europe, earlier this week thanked Queensland Police and the community for their support in trying to recover her 'life box'.

The Australian Olympic Committee had offered to replace her Sydney 2000 medal if it was not recovered.

Three-time Olympian Katrina Powell is still hoping her two Olympic hockey gold medals will be returned following the robbery at her Perth home last week.

If the former Hockeyroo's medals are not recovered the AOC will work with the IOC to replace them.
