When the star's comments inevitably filled up with a mix of support and negativity, Brooke further elaborated on her Instagram Stories.
The reality TV star asked her followers to "please refrain" from making comments about her "connections" or receiving an "exemption."
"These are totally invalid to my situation," she wrote. "I'm a WA resident. But I'm not coming back to WA for work/essential work, therefore I can not really apply for any exemption.
"As for compassionate grounds, I was allowed in last time under compassionate grounds but still had to quarantine two weeks," she wrote, of travelling home for her sister's funeral last August.
"That wouldn't be an accurate cause as time would be a consideration for them (the government).
"As for 'connection' I don't have some magic strings to pull. Even if people did, I wouldn't feel entitled to that," she continued. "Everyone is patiently waiting to get back home."
Brooke finished off by saying that, while the two week quarantine is something she's considering, she isn't quite ready to do it again after the previous two times.
"I'm already in a vulnerable state of mind with what's been going on," she wrote. "I'm building myself up to it. If it comes to it, I will prep myself for quarantine."
Brooke wasn't the only one upset by the decision, with Channel 7 TV Presenter Abbey Gelmi sharing the news headline with followers.
"I'm so angry I don’t have words. @mark_mcgowan_mp is out of control. @scottmorrisonmp do something. Anything. We just want to see our loved ones," she wrote on her Instagram.
TV Presenter Riana Crehan said she just wanted to reunite with her family, after her father passed away in the past two years of border closures.
"We just want to see our loved ones," she wrote. "We have missed Birthdays, Weddings, Births, Deaths and time. We have missed precious time. Time we will never get back. We have done what you asked. My question is what have you been doing?"
