Incredible scenes were witnessed over Sydney Harbour today as KIISFM radio host Kyle Sandilands and his pregnant fiancée Tegan Kynaston hosted a spectacular gender reveal party with family, friends and celebrity guests including Sandilands’ co-host Jackie O Henderson.

Red Bull Air Race world champion and former RAAF top gun fighter pilot Matt Hall was charged with the honours of revealing the gender of their baby, alongside Emma McDonald, emerging elite air racing pilot.

Sandilands, 50, announced he is expecting his first child with Kynaston, communications director, 35, last week following their engagement in January this year.

The superyacht was located at Bradleys Head in full view of the happy news. A trail of vibrant blue smoke travelled throughout the harbour as the planes flew past the yacht over to Kirribilli, the Sydney Harbour Bridge, Opera House and Mrs Macquarie’s Chair before returning east to the heads.

Hall was excited to be part of the occasion, “This is something very different for us and an interesting challenge from a planning and testing perspective.

It’s a special time, welcoming a precious life into the world and this little baby will certainly know he or she is very loved.

Emma and I are definitely very humbled to deliver the exciting news”, he said.

Matt Hall Racing has been working closely with the team at KIISFM for many weeks in preparation for what they believe is the first time a gender reveal of this nature has been performed in Australia.
