Sydney: Marnus Labuschagne hit his fourth century in just 14 Tests to guide Australia into a commanding position against virus-hit New Zealand on Day One of the third Test in Sydney on Friday. The rock-solid No. 3, last year's leading Test scorer with 1,104 runs at 64.94, again proved the Black Caps' nemesis with his second ton of the series to continue his remarkable scoring sequence.

Supported by Steven Smith's 28th Test half-century, Australia reached stumps at 283 for three with Labuschagne unbeaten on 130 and Matthew Wade a breezy 22 not out. The South African-born Labuschagne has now scored four centuries in seven Test innings this southern summer against Pakistan and New Zealand. "Terrific day," he said. "When you bat on Day One you know it can be a real prosperous day but if you get off to a shaky start it can be tough work.
