“Saski Collection 100% profits today are going to emergency relief for the Australian bushfires,” read the caption from the since-deleted post.
The backlash that ensued got so bad that she ended up deactivating her Instagram account completely, The Daily Telegraph reports.
After a while, the model reactivated her account with a fresh post that didn't distract from what she was trying to get across.
Tammy initially urged her fans to help donate last week, with an emotional post on Instagram.
Our home is burning. These are the worst bush fires on record and they are still burning,” she wrote.
"Five million hectares (15 MILLION ACRES!!!) of land has burned. Our wildlife are burning alive (more than 500 MILLION!!) and many homes have been lost.
"I stay praying for all the families and the firefighters and the lives lost," she added.
Celebrities such as Kylie Jenner, Selena Gomez, Pink, Margot Robbie, Chris Hemsworth, Nicole Kidman and more have been donating to the cause.
