The 26-year-old striker has been at the forefront of the women's game in Australia ever since she made her international debut in 2007, at the age of 16.
She was the first Indigenous Australian - male or female - to score for Australia and was a member of the all-conquering Matildas team that won the Asian Cup in 2010.
Now at 26, she's still regarded as one of the "juniors" in the Matildas squad, with the experience of a player beyond her years having represented the national team 74 times, while scoring 22 goals.
Despite her past successes, she believes the time is right for the Matildas to challenge for the upcoming women's World Cup in France.
"It's not out of the question," Simon told SBS News.
"It's a very realistic goal. I believe we have the talent and ability within the group.
"In the last couple of years we have created a new found belief within the group that we can (win the World Cup)."
Simon's confidence stems from results the Matildas recorded against some of the game's super powers, including victories over Japan, Brazil and the US.
"If we can continue to go in the right direction, which we have been, by no means is it out of the question," she said.
"It's a very realistic goal as a national team."
Simon will make her return to the W-League on Friday when she makes her debut for Melbourne City against Perth Glory.

She spent a season in the National Women's Soccer League representing the Boston Breakers.
Guiding Melbourne City to a third consecutive national title was Simon's priority.
She said it was difficult comparing the NWSL with the W-League.
"They're very different leagues," she said.
"I've been thankful to have played four seasons over in America. I've been here from year one with the W-League so you can't really compare to be honest.
"They're different styles of football and different standards. The great thing is that we're able to play in that league but also come home and play at home in front of family and friends."
