United front! Siblings Bindi and Robert Irwin arrive at Brisbane Airport alongside mother Terri ahead of emotional anniversary

The Irwin family appeared closer than ever as they left the airport on Monday, two days before the 18th anniversary of Steve Irwin’s tragic death.

Bindi Irwin, 25, was a real mother as she walked through Brisbane airport with her two-year-old daughter Grace Warrior.

She was joined by her husband Chandler Powell, her brother Robert, 20, and her mother Terri after their visit to North Queensland for their annual Croc research trip.

To steal the show with her family, Bindi opted for comfort in a casual checked shirt over a grey T-shirt, paired with light blue jeans and white sneakers.

She appeared relaxed yet focused as she carried Grace, who looked adorable in a pastel pink jacket and matching pants, while holding a children’s book.

The Wildlife Warrior looked comfortable and casual, wearing a gray cap.

Walking next to her was Bindi’s husband Chandler, 26, who looked like a real pillar of support.

Chandler wore a black T-shirt, beige shorts, and hiking boots, with a large backpack over his shoulder.

Robert seemed in a cheerful mood and his broad smile was a clear sign that the family continues to find joy, even in difficult times. He was chatting with a male friend.

Meanwhile, their devoted mother Terri, 60, was spotted walking apart and keeping a low profile.

The Irwin matriarch opted for comfort in a blue Steve Irwin Wildlife Reserve T-shirt, lightweight jeans and practical gray sneakers.

She added a touch of discretion with a black face mask and a cap, her backpack slung over her shoulder as she walked briskly through the airport.
