Kyle Sandilands set to marry fiancée Tegan Kynaston at one of Sydney’s most prestigious homes

Kyle Sandilands is going to marry his fiancée Tegan Kynaston on Saturday at Sydney’s famed $60 million Swifts mansion in the posh suburb of Darling Point.

The 51-year-old radio king has rented the stunning Grade II listed Gothic mansion to use as the venue for his lavish, star-studded wedding and reception.

The lavish property is the perfect venue for Sandilands lavish wedding, on which he reportedly spent $1 million.

It’s unclear what Sandilands paid to use the beautiful property for its big day, but renting the property for one night costs more than $20,000.

On Monday’s Kyle And Jackie O Show, the radio titan and his co-host Jackie “O” Henderson challenged listeners to guess the cost of specific elements of Kyle’s wedding in a game called “Higher or Lower.”

‘Do you know where I made the mistake? When I first met the wedding planner and wedding stylist… they said, “Okay, what budget are we on?” and I said, ‘There’s no budget,'” Sandilands said at the beginning of the segment.

As the quiz went on, it became clear that Sandilands may have poured as much as a million dollars into the lavish affair.

One of the most expensive features was the floral arrangements, which cost a whopping $150,000.

Henderson, who spent just $80,000 on her wedding to ex-husband Lee, was stunned by the price tag and asked Sandilands, “150,000 for something that dies a few days later?”

“Well, everybody can take home flowers and stuff,” Sandilands shrugged.

Tegan’s wedding dress costs less than $50,000, while the bridal party and pageboy suits cost more than $15,000.

The entertainment, which included renting multiple stages, audio equipment, and sound trucks, meanwhile cost more than $100,000.

Sandilands clarified that he actually saved money on the artist fees, as his pop star friends Guy Sebastian, Conrad Sewell and Samantha Jade had agreed to perform for free.

The wedding stylist’s fee was less than $250,000, while the food — which included an oyster bar and caviar — cost less than $75,000.

Sandilands revealed he spent less than $120,000 on security details, including 15 private security guards and members of the NSW and federal police.
