She thanked the "incredibly accommodating staff" who had made "the last few VERY CHAOTIC days easier for myself and the kids".
"Nothing like spontaneously packing at 2am right," Sophie said. "We were all tested at the airport yesterday (on Wednesday), are all NEGATIVE."
Event organiser @sociallyem said she had come up with a plan for Sophie and Emmy to come to Perth earlier than anticipated to avoid getting stuck in Melbourne.
"We didn't want the same thing to happen that happened in March, we had to postpone the event because of a Covid lockdown," she said in a video shared to her Instagram stories.
"So we acted really quickly this time, I threw a crazy idea out to the girls and said, 'hey, do you want to jump on a plane the second we heard of any Covid situation going on in Melbourne."
Fashion influencers face 'massive kick in the guts'
The timing of Melbourne's snap lockdown couldn't be worse for many of the city's influencers as Afterpay Fashion Week is due to start in Sydney next week.
Identical twins Marissa Sohtra and Rebecca Loucas, who run popular fashion Instagram page @twiceblessed, revealed they had to shelve plans to come to Sydney.
The pair had been due to fly to Sydney on a 6.30pm flight on Thursday night, but had cancelled after NSW announced anyone coming in from Melbourne would still need to follow lockdown orders.
Sohtra and Loucas wrote on their Instagram story that the lockdown had come as a "massive kick in the guts".
"Going to fashion week isn't just a 'flashy time to show off' nor is it 'wanky' or out of touch, it's our job," they said.
"The income and potential income generated from FW [fashion week] sustains us financially for months."
The sisters said it was "incredibly frustrating" to miss out on the event after last year's fashion week was also cancelled because of the pandemic.
"Just as we were rebuilding financially after the horror that was 2020, and spending all this money to get to Sydney, it's gut wrenching to be in this position again," the pair wrote.
