King Willem-Alexander and his wife Queen Maxima of the Netherlands continued their state visit to Australia by attending a concert at the Sydney Opera House on 2 November.

The Dutch King and Queen are visiting the country to commemorate the 400th anniversary of the landing of Dutch explorer Dirk Hartog. The royal couple appeared in high spirits as they posed for photographs following the concert.

Australian Prime Minister Malcolm Turnbull can be seen playfully gesturing as he stands next to Willem-Alexander and Maxima in one shot, as his wife Lucy Turnbull, Governor General Peter Cosgrove and Lady Cosgrove look on.

Maxima – who is renowned for her bold and colourful style choices – looked sensational in a green and teal colour-block satin floor-length gown which featured a grey waistband to highlight her svelte figure.

Enhancing the glamour, Maxima wore her blonde hair in a voluminous updo and donned statement jewels to seal the look. The accompanying ladies wore black gowns while the men dressed in black tie.

Ahead of the concert, the Dutch royals and the prime minister and his wife posed for snaps outside the impressive Sydney Opera House as they waved to onlookers. Maxima and the prime minister's wife appeared to get on famously as they chatted among the audience before the show commenced.
