An Aussie couple’s dream wedding reception went unexpectedly viral after a video captured the moment a lavish floral display caught fire.

The bride, who looked stunning in a floor-length, long-sleeve gown, and her groom made a grand entrance into their wedding hall, greeted by a drumming circle.

The guests cheered as the newlyweds entered the venue and did a small dance, smiling and gazing at each other lovingly as they celebrated becoming husband and wife.

But unbeknownst to the couple, trouble was brewing in the background.

The decorative pyrotechnics that were dotted along the walkway into the hall had ignited a floral arbor at the entrance.

Within seconds, the arch, filled with white and pastel pink flowers and attached to a wooden frame, burst into flames.

But the couple seemed blissfully unaware, continuing their dance as the flames grew larger.

The footage, shared on TikTok, even shows some guests and performers glancing nervously at the fire, yet no one appears to raise the alarm or alert the couple.

As the video gained nearly half a million views, viewers were quick to comment on the bizarre scene.

“Love how the drummers played still like when the Titanic was sinking and the violinist still played – dedicated,” joked one.

“(The couple) were oblivious to it all, now that’s love,” quipped another.

However, many voiced concern over everyone’s lack of action.

“Considering people noticed the blaze immediately, this could have all been avoided if someone had asked the staff members for an extinguisher,” said one.

“Seriously, no one stopped to let them know there was a fire?” questioned another.

Others questioned the use of pyrotechnics indoors, especially near flammable decor.

“Indoor fireworks need to be banned,” claimed one.

“This is unacceptable and shouldn’t have happened,” wrote someone else. “Imagine if someone got hurt.”

Meanwhile, some just shared their sympathies.

“My heart goes out to the wedding couple,” said one. “I hope they were still able to enjoy their day.”

The poster then shared a follow-up clip, showing guests standing on the waterlogged floor after the fire sprinklers were triggered.

The once stylish room was now flooded with water, the tables were abandoned and guests were standing around, unsure of what to do next.

It is unknown what wedding venue this occurred at.
