The first Hologic WTA Tour tournament is set to kick off on New Year's Day at the Adelaide International 1.

This year, Memorial Drive will host back-to-back WTA 500 tournaments, starting with Adelaide 1 and following a week later with Adelaide 2. Both tournaments feature top-flight fields, as the tour's best look to get their seasons underway ahead of the first Slam of the season at the Australian Open, which begins on Jan. 16.

Here's everything you need about the two weeks of tennis in Adelaide:

When do the tournaments start?

Adelaide 1 will begin on Sunday, Jan. 1, with Adelaide 2 commencing on Monday, Jan. 9. Adelaide 1 features a 30-player singles draw and a 24-team doubles draw. Adelaide 2 also features a 30-player singles draw, but a slightly smaller doubles draw at 16-teams.

Both tournaments will be played on outdoor hard court using the Dunlop Australian Open ball. Both events are joint ATP/WTA events, with the ATP holding ATP 250 tournaments each week.

When are the finals? 

Adelaide 1: The singles final will be played on Sunday, Jan. 8, at 4:00 p.m. The doubles final will be played on Saturday, Jan. 7, at noon. 

Adelaide 2: The singles final will be played on Saturday, Jan. 14. at 4:00 p.m.  The doubles final will be played on Friday, Jan. 13 at noon. 

Who are the defending champions? 

Adelaide hosted a WTA 500 and WTA 250 last January. Ashleigh Barty swept the Adelaide 500 singles and doubles titles, defeating Elena Rybakina in the singles final and winning doubles with Storm Hunter. 

Madison Keys won the Adelaide 250 title, defeating Alison Riske in an all-American final. Japan's Eri Hozumi and Makoto Ninomiya took home the doubles title.
