This marked Rafael Nadal's first tournament appearance since being forced to retire injured at the 2023 Australian Open. The Spanish veteran, aged 37, showcased his dominance against the Australian wildcard Jason Kubler, who struggled to pose any threat. Nadal's next opponent in the Brisbane International quarter-finals will be another Australian, Jordan Thompson.
