John Millman defeated Marc Andrea Huesler 6–7, 7–5, 6–7, 6–2, 6–3 in the first round of the Australian Open on hard court. Despite entering as the underdog at 2.25 odds against Huesler's 1.72 favourite status, Millman recovered from two set deficits to claim a five-set victory. The Australian's comeback was anchored by improved form in the fourth and fifth sets, where he secured consecutive breaks to seal the match. Millman's ability to weather the Swiss player's early pressure and execute in the closing stages proved decisive. The result sends Millman through to the second round and suggests renewed competitive form heading into the tournament's early stages.
