"As a parent of colour, I am always conscious of the presence — or absence — of diverse representation in kids' pop culture, what it means for children and the conversations we have around that," she added.
"I sincerely believe you don't have to be 'Other' to think about this too."
She said the show could do with depicting more diverse people.
"Where are the disabled, queer, poor, gender diverse, dogs of colour and single-parent dog families in Bluey's Brisbane?" she wrote.
"If they're in the background, let them come forward. (Maynard, voiced by Sean Choolburra, I'm looking at you.)"
Her article has caused an uproar on social media, with many accusing her of politicising an innocent children's show, while others agree she raises a valid point that needs to be discussed.
"Not. Everything. Has. To. Be. Political," one person said on Twitter.
"Why can't people just enjoy the simple things in life without viewing them through the prism of race, gender and other socio-political messages?" another one asked.
Others also came out in Wang's defence.
"It was the gentlest, most soft piece about the topic and full of praise for Bluey. What is actually wrong with people that we can't talk about these things in this country?" one Twitter user said.
"Beverley Wang's observation about diversity in Bluey is a small part of an appreciative column about what the show means to her. Doesn't read like an offensive in the culture wars," another person wrote.
