The 48-year-old, who has cerebral palsy, “cried his eyes out” when he found out he would be able to take part in the Abseil for PMH.
Mr Sully’s neighbour Alicia Tavani had wanted to sign up for the event as part of her fundraising campaign as the Wanneroo representative for Miss Teen Galaxy Australia.
But at 14 years old she was told she was too young.
“Robert and I have always spoken about when Robert turns 50 we will skydive together as it’s one of Robert’s dreams but that is in a few years’ time,” Alicia said.
“When I was told I was too young, I asked if Robert would be able to take my place.”
“As soon as I got the approval, I went over and spoke to Robert and told him what I had organised for him to do.
“He cried his eyes out that somebody was giving him the chance to be able to do something amazing and because he feels so privileged to be able to fundraise for an organisation that is very close to his heart.”
Mr Sully will abseil down the QV1 building on St George’s Terrace as part of the event from May 5 to 7.
One of his carers Barry Dyer and Alicia’s dad Paul Tavani will join him.
For Mr Sully to take part, he will take a lift to the 39th floor, then be carried another flight of stairs to the 40th floor with the help of his carers and event organisers.
“Robert has asked me still to be there with him during this time and help him out to the 40th floor,” Alicia said.
“Then I’ll be waiting down on the ground with a bottle of water when he comes flying down.”Each member of the abseiling team must raise a minimum of $500.
