Australian Open: Nick Kyrgios' colourful language lands him in soup

Australia's volatile Nick Kyrgios has been fined for a colourful directive to the rowdy crowd during his opening round win at the Australian Open.

The 22-year-old was slapped with a $3,000 penalty for unsportsmanlike conduct early in his 6-1 6-2 6-4 win over Brazilian Rogerio Dutra Silva in a night match on Hisense Arena on Monday.

The Australian was among six players fined a total $15,000 for indiscretions in qualifying and the main draw's first phase at the year's opening Grand Slam.

Croatia's Borna Coric was hit with a $5,000 penalty for racquet abuse during his defeat to Australia's John Millman.

Argentina's Diego Schwartzman and Romanian Marius Copil were fined $2,000 each for the same offence.

Kazakhstan's Alexander Bublik was handed two $1,000 fines and American Stefan Kozlov was penalised USD 1,000, both for audible obscenities during qualifying.
