The star sang at an intimate concert for just a few hundred music industry figures, celebs and media personalities at the Wildfire venue on Sydney harbour overlooking the world-famous Opera House and bridge.
Kyle, 43, performed five acoustic songs at Monday night's packed bash, including her 1988 hit, I Should Be So Lucky.
On stage, Kylie told how glad she was to be back home in Australia for her Aphrodite world tour.
She said: 'I'm absolutely beside myself. I'm finally home.'
Kylie performs three concerts for her fans in Sydney this week before heading to Melbourne, her home city, to continue the Oz leg of her tour.
