Teri Hatcher, best known for starring in Desperate Housewives, is also heading to the Sydney expo but is charging considerably less for her starpower with fans having to fork out $70 for an autograph and $80 for a picture.
Since the announcement, most fans have taken to Twitter to express their excitement over Hemsworth even making an appearance at the popular expo but plenty have also tweeted their outrage over the hefty price.
Another user angrily slammed the affordability of the meet and greet.
"I just looked up the price list for Chris at supanova and its $200 for autograph and $210 for a photo what the f**k i cant afford s**t," they wrote.
The backlash became so severe that Supanova themselves responded to the criticism after a fan wrote "either Chris' manager is being hard to work with, or you're taking advantage of Chris' appearance and charging us more ..."
The Supanova expo travels all around Australia and draws numerous celebrities to the comic and gaming event.
The expo, which was last in Melbourne in April, drew the likes of Game of Thrones star Natalie Dormer (who charged $80 for an autograph), Wolf Creek star John Jarratt ($40 for an autograph) and Bones and Buffy star David Boreanaz (who charged $100 for an autograph).
