Sandow grew up in Queensland, playing rugby league in the Aboriginal community of Cherbourg, a three-hour drive north-west of Brisbane.

He later moved to Brisbane, where he attended Marsden State High School with Israel Folau and Antonio Winterstein.

In 2006, while in year 12 at Marsden State High School, his classmates were Israel Folau and Antonio Winterstein.

[7] Sandow began playing in the National Youth Competition for the Rabbitohs squad, from the beginning of the 2008 season.

At the time Sandow was to make his début the club were sitting at the bottom of the NRL competition ladder.

In round 13 during the 2008 season, Sandow made his first-grade début against the Warriors in Auckland, New Zealand at Mt.

Sandow's fairy-tale start to his NRL career continued a week later in round 16, when after trailing 28–4 to the North Queensland Cowboys and coming back to level the scores at 28–28, he kicked the game-clinching field-goal to win the match 29–28, in what became the second biggest comeback victory in the history of the National Rugby League.

[10] Sandow's first two-years with the Parramatta Eels proved to be a struggle as his performances were inconsistent and he spent time in the New South Wales Cup, with the Wentworthville Magpies.

On 20 December 2017, Sandow signed a contract to join the Moranbah Miners in the local grade A Mackay rugby league competition for the 2018 season.

[22][23] Sandow earned selection in the Indigenous All Stars team, that defeated the New Zealand Māori 34–26, in a curtain-raising game at the Rugby League World Cup Opening Ceremony in October 2008.

On 2 January 2017, Sandow was charged with a public nuisance offence after being filmed in a street brawl in Queensland's South Burnett Region.

[25] On 10 January 2017, Sandow was fined $300 at Murgon Magistrates Court in Queensland over the brawl and he escaped conviction.

He also faced charges of dangerous operation of a motor vehicle, two counts of driving without a licence and evasion.
