11:45 a.m.

With center stage to be taken by Ash Barty and Danielle Collins in the women’s singles final later in the day, the junior boys and girls finals were first up on Rod Laver Arena.

Top-seeded and 16-year-old Petra Marcinko of Croatia plays eighth-seeded Sofia Costoulas of Belgium in the junior girls final. Top-seeded Bruno Kuzuhara of the United States plays fourth-seeded Jakub Mensik of Czech Republic in the boys championship match.

Kuzuhara, 17, is Brazilian-born but moved to the U.S. with his Japanese-heritage parents when he was an infant. The Florida-based Kuzuhara has already won the junior boys doubles title with Coleman Wong of Hong Kong — they beat American Alex Michelsen and Adolfo Daniel Vallejo of Paraguay 6–3, 7–6 (3).

The junior girls doubles title has also been decided — Clervie Ngounoue of the U.S. and Russian Diana Shnaider beat Canadians Kayla Cross and Victoria Mboko 6–4, 6–3.

After the Barty-Collins singles championship match, the men's doubles final features an all-Australian lineup. The crowd-pleasing and so-called “Special K" team — Thanasi Kokkinakis and Nick Kyrgios, play Matt Ebden and Max Purcell.
