They are sweet, juicy and, unlike cattle or sheep, they do not put up a fight - mangoes are the latest target for highly organised gangs of poachers in Australia.
As farmers in Queensland, the Northern Territory and Western Australia begin this year's harvest, thieves are launching night-time raids and stripping orchards of tens of thousands of dollars' worth of fruit.
Some farmers have resorted to hiring security guards to protect their crops.
'There are at least half a dozen around here who have taken on security guards,' said John Morton, chairman of the Burdekin District Mango Growers' Association, in northern Queensland.
'Three years ago I got hit really bad. They stole A$30,000 [HK$132,000] worth in a single night. Since then I've put up an electric fence round my orchards.'
So far, none of the poachers have been caught. Police have advised growers not to confront the thieves because they could be dangerous.
'We are not going to go up to them and be John Wayne,' Mr Morton said. 'The advice is to take their number plates and ring the local police station.'
