Later in the day, Albanese also responded to calls for a public holiday to be declared.

"Too late to call a national holiday after the @Socceroos huge win against Denmark last night. But if we win the #FIFAWorldCup... that might be a different story," the prime minister wrote on his social media.

On Sunday, Australia will face the football powerhouse, Argentina in their last 16 showdown as early as 6:00 a.m. local time.
