Sydney - A daredevil Australian couple will leap from a hot-air balloon at 12,000 metres in the hope of gliding safely back to earth using what skydivers call wingsuits, news reports said Monday.

Glenn Singleman and Heather Swan expect to be in the air for 7 minutes and glide 30 kilometres after jumping from the balloon above the Outback town of Alice Springs.

The wingsuit gliding record they hope to break Tuesday is held by a Spanish team who flew 20 kilometres above the island of Gibraltar in the Mediterranean.

The Australian pair hold the a world record in BASE jumping which they set in India in 2006. (dpa)
