UFC is back in Australia this weekend with a pair of title fights atop the marquee. It's a big one in Sydney when middleweight champion Dricus du Plessis takes on former champion Sean Strickland in the main event.

With both fighters being deceptively difficult to kill, their first encounter back at UFC 297 ended up being a tactical, back-and-forth battle that saw Du Plessis narrowly scrape out a split decision win on the scorecards to become the new champion at 185 pounds.

In the co-main event, China’s Zhang Weili (25-3) will defend her strawweight championship against top-ranked challenger Tatiana Suarez (11-0) of Rancho Cucamonga, California. Zhang has won her past three title defenses, two by unanimous decision and the other by second-round submission.
