Nick Kyrgios dedicated his Hopman Cup title to late coach Darren Tandy after powering Australia to victory in Saturday's final against Ukraine at Perth Arena.

Australia's 17-year Hopman Cup title drought came to an end after Kyrgios and Daria Gavrilova secured singles wins in the decider.

Gavrilova's 6-4 7-6 (8-6) victory over world No.19 Elina Svitolina gave Australia Green the perfect start, before Kyrgios wrapped up the job with a 6-3 6-4 demolition of Alexandr Dolgopolov.

Australia's only previous Hopman Cup title came back in 1999, when Mark Philippoussis and Jelena Dokic took out the crown, beating Swedish pair Jonas Bjorkman and Asa Carlsson in the final.
