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 main event of UFC 312 tomorrow night the middleweight title is on the line in a rematch. Champion Dricus Du Plessis (22-2) will look to successfully defend his title for the second time as he faces off against the man he defeated to become middleweight champion, Sean Strickland (29-6).
