Chris Hemsworth And Elsa Pataky Help Out At Their Kids' Byron Bay School

First, he had to defeat Thanos, then he had to show up for lunch duty.

Just days after his mega-blockbuster Avengers: Endgame hit cinemas, Chris Hemsworth was there to fight a different villain... lunch.

Alongside wife and Tidelands star Elsa Pataky, Hemsworth carried tubs of supplies and helped roll sushi rolls for the students of Byron Bay Public school alongside other parents (aka the lunchtime avengers).

Pataky posted updates throughout the day of herself and Hemsworth challenging each other as to who was helping out the best, captioning one quick vid, "Always helpful to have a superhero in the kitchen!!"

While the pair looked like they were having a blast volunteering in the canteen, the school had just hours earlier been thrown into chaos when a teacher was allegedly attacked by a parent with a pair of scissors.

Zane Vockler, 28, was rushed to Tweed Hospital in a stable condition following the attack, with the school going into lockdown for the morning.

It appeared the A-lister parents were there to lift some spirits, joking with the others in the canteen about their help. After being told Hemsworth didn't do "too bad", the Thor star joked, "Too bad? We dominated! Dominated!"

Parents to India, 6, and twins Tristan and Sasha, 5, Pataky and Hemsworth are no strangers to getting involved in their kids' school. In a GQ profile last year Hemsworth revealed one of his greatest triumphs as a father -- and possibly in life -- was when he competed in a "running of the dads" at India's field day.

"There was just this wave of nirvana," Hemsworth said while recalling his victory, "I turn around, and I go, 'Where's my daughter? Where is she?' And she's like, 'Dad, did you win?' And I'm like, 'Did I win? You didn't see it?!' They gave me a sticker. A first-place sticker."

Even Pataky admitted she had never seen her husband so excited, "Not even about getting a big job... it was probably one of the best things that has happened to him in his life, which is funny, right? All the things he has achieved."
