The 21-year-old Simmons has starred in his rookie National Basketball Association season for the Philadelphia 76ers, sparking comparisons between the Melbourne-born player and legend LeBron James.
Not only was Simmons not among the original 12 players selected for the Eastern Conference All-Star team, but he was passed over three more times.
But Mr Watts wasn't finished there, saying another overlooked Australian could be proof of a wide-ranging, anti-Aussie conspiracy that goes all the way to the top of the National Basketball Association.
The rant has had some cut-through, with ESPN already picking it up.
"He's already an National Basketball Association superstar, breaking first-year records held by greats of the game like Magic Johnson and Oscar Robertson".
Ben Simmons' exclusion from the NBA All-Star game has lead to a freaky rant in parliament from an Australian MP.
Someone check on Tim Watts.
Zaha out for a month
Crystal Palace manager Roy Hodgson has announced winger Wilfried Zaha will not be available for the Eagles game againstEverton this weekend.
"I paid particular tribute to South-Sudanese Australians Thon Maker and Mangok Mathiang who have not only reached the pinnacle of their profession, but did so after overcoming the challenges of arriving in Australia as refugees", Watts said.
"They show that Australia's diversity is our strength". However, his response on Thursday to a tweet that shamed the National Basketball Association for choosing Walker over Simmons was fairly ambiguous.
The story was also covered by the likes of USA Today, who expressed bemusement at the fact the issue was raised in Parliament.
In the initial speech, Mr Watts cited Simmons' statistics - and the case of Utah's Joe Ingles - as reasons why he was concerned with the NBA's decisions.
As for Simmons, he put in a star turn in his most recent game - against the Washington Wizards - dropping 15 points, eight assists, six rebounds, three steals and a block as the 76ers scored a 115-102 win.
Simmons was certainly a candidate as a replacement.
"It makes me think there is some kind of anti-Australian conspiracy going on at the league head office at the moment".
