Glider pilots from around Australia are hoping for another few weeks of ideal conditions to 'ride' the rare Morning Glory cloud in north-west Queensland's Gulf of Carpentaria.
It is the only place in the world where the meteorological phenomenon can be reliably predicted and is seen every year during September and October.
Lyn Battle from Sweers Island, in the Gulf, says this year's clouds have been spectacular and pilots say it is the ultimate experience to glide on one.
"We had one a couple of weeks ago and we got on to the guys at the weather bureau and they were able to look at the satellite pictures," she said.
"It stretched from north of Karumba, across Sweers, all the way across the Gulf to Groote and almost up as far as Gove.
"That's about 1,000 kilometres, that's a long cloud."
She says it is rare to see.
"We've had some very spectacular clouds this year, better than last year," she said.
"We've had some from the south, which is very unusual and it's all to do I think with the early humidity, which bodes for a good wet season.
"It's become very popular - I was in Burketown the other day and there was a whole range of gliders and ultralight-type aircraft.
"There's a Japanese film crew back in town again."
