He played college football for the Utah Utes, where he won the Ray Guy Award and was a unanimous All-American as a sophomore in 2016.

Wishnowsky was born in Gosnells, a suburb of Perth, Western Australia, to New Zealand parents from Hawke's Bay.

He grew up playing Australian rules football, but was forced to give up the sport at age 18 due to repeated shoulder injuries.

While the work paid well enough for him to purchase a house in his hometown near Perth along with his best friend, he grew to hate the job and sought another career path.

Although no longer playing full-contact Australian rules, he continued to play a flag version of the sport alongside several friends, one of whom had a connection to Prokick Australia, a training centre in Melbourne that converts Australian rules players into gridiron football punters.

By that time, Utah had brought in earlier Prokick graduate Tom Hackett, and were pleased enough with him that they reached an agreement with Prokick director Nathan Chapman to leave a scholarship open for Wishnowsky once Hackett's Utah career ended after the 2015 season.
