"Set on the western side of Circular Quay, the Museum of Contemporary Art Australia (MCA) is the country’s leading institution for modern art. While access to touring international exhibitions from the likes of Tatsuo Miyajima and Annie Leibovitzincurs an entrance fee, the permanent collection of more than 4,000 contemporary works by Australian and Torres Strait Islanders, from Gary Carsley to Lena Yarinkura—plus a rare collection of artist notebooks, music, letters, and sketches—is always free. Come on Wednesday night when the gallery is open until 9 p.m., or for the adults-only Art Bar on the last Friday of the month. The rooftop café offers occasional live music and DJs plus glittering views of the Sydney Opera House and Harbour Bridge after dark."
