Some overseas websites have reported on the SA discovery, speculating whether the remains belonged to the UK girl.
The bones were found earlier this month in scrub alongside the Karoonda Highway near Wynarka, east of Adelaide.
Police believe they belong to a fair-haired girl aged between two-and-a-half and four who may have been murdered up to eight years ago.
Supt Bray says a task force set up to investigate the girl's death has taken more than 500 reports through Crime Stoppers.
