It's quite confusing because the story sounds identical. The one obvious change is their hairstyles, but I could imagine if they were fleeing they might cut their hair and probably don't have access to Saudi family money for beauty (like hair straightening).
I just find it a little too coincidental that they were the exact same age, both sisters with the same age gap and both escaped in the same month from the same place. There have only been 80 or so Saudi women applying for asylum over a several year period.
Thanks Garcelle. It seems to me the twitter link and other information demonstrates fairly conclusively that the two women who died in Sydney (Asra and Amaal Alsehli) are
not/not identical with the two who (Reem & Rawan) were intercepted in Hong Kong and escaped from there to a third country.
Dates of travel and twitter usage
1. The twitter link -
https://twitter.com/hksisters6 - takes you to a twitter page that says "Joined February 2019". This refers to the flight of Reem & Rawan. [Not their real names.]
2. On 26 March, a person wrote on the hksisters6 account: "Now we’re in safe place, and we would like to live our life without fear. We’ll live normally away from the media. And again THANK YOU

Be strong!"
3. According to a
CNN report - which details the flight of Reem & Rawan / hksisters6 and is worth reading - Reem & Rawan began their escape on September 6, 2018.
4. The Alsehli sisters came to Australia in 2017 and were living safely in Australia by 2018.
Ages
According to multiple press reports - from reputable sources - at the time of their death, Asra Alsehli was 24 and Amaal Alsehli was 23. When they came to Australia in 2017, Asra Alsehli was 19 and Amaal Alsehli was 18. According to the CNN report cited above, Reem was 20 & Rawan was 18 in 2018 when they made their escape. That is a two year age difference. For the Alsehli sisters, the age gap in one year.
So what do we have:
1. their ages are different, in terms of birth gap and also at the time of their escape.
2. the dates of their escape are different - in fact, the Alsehli sisters were already in Australia.
The similarities are: they are female, they are human and they are Saudi, and trying to flee repression based on religious mores.
Conclusion: They are not the same sisters and there is nothing "coincidental". This false identification.
Given that the claim the Alsehli sisters escaped via HK, was based on this false identification,there is, on this basis, no reason to conclude the Alsehli sisters came to Australia via HK. They may have - the Australian government will have the records - but this false identification is not sufficient to conclude they travelled to Australia via HK; or that they had $5,000 with them.
The Sydney Morning Herald - already cited - tried to set this false identification straight, but other less reputable sites, that do not fact check, continued to repeat this falsehood. Simple research and basic analysis would have shown the journalists that the identification of the two sets of sisters was wrong.
