He added: "With the first ball all I wanted to do was try and hit the stumps, then I just wanted to repeat that with the second.
"When it came to the third I don't know, I was in a dream. The crowd were really helpful, and with that third ball I wanted to do it more for them than for me."
Newell said his family hadn't witnessed his feat at first hand but explained it didn't take him long to tell his wife.
"She was in the car when I called, with my two sons. They were all cheering and screaming when I told them."
Newell said he would use the money for a family holiday, ideally to witness England in Ashes action in Australia later this year.
"If we can get tickets we'll go to Melbourne for the Boxing Day Test at the MCG (Melbourne Cricket Ground) later this year, but if not the Caribbean."
Before that series, England defend the Ashes against Australia on home soil, with the first Test at Trent Bridge next month.
Former England captain Michael Vaughan joked on Twitter that, having seen his bowling, Newell should be fast-tracked into Australia's squad.
