The Dutch King and Queen will head to the racetrack on day two of their Perth visit.
King Willem-Alexander and Queen Maxima will meet with trainers, owners and jockeys in the mounting yard, walk through the crowd and grandstand before watching the Melbourne Cup.
Fashion aficionados will be keen to see what the glamorous Argentinian-born Queen Maxima wears, given she is known for her chic sense of style.
On Monday, she stood out in a beige and green dress by Dutch designer Mattijs van Bergen with a matching fascinator, gloves and jewel-encrusted necklace.
