What is believed to be the world's longest pineapple has gone under the hammer for charity in far north Queensland.
Cairns resident Coral-Leah Kemp has spent the last two years tendering to the juicy fruit, which grew to 35 centimetres tall and 6.8 kilograms on her first attempt on growing a pineapple.
She even created an Instagram page for her pride and joy, called pricklypiney.
'I've been watching this mega pineapple grow for months and had no idea it would get so big,' she told the ABC.
'It's the first pineapple I've ever grown and it's turned into a monster. It's quite an unusual shape as well.'
While it's taller than Northern Territory woman Christine McCallum's effort in 2001, it missed out on the world record for being the world's biggest pineapple because it's 1.4 kilograms lighter.
In far north Queensland, pineapple is sold at $2.29 per kilogram, which means the monster fruit would sell for $15.50 if sold at market price.
