Not to overthink about this or anything, but the consequences of some of Phryne's decisions are hilarious and genuinely life changing in ways that the show never touches on.
Phryne flies to England. In doing so, she becomes the first woman to fly solo between the two countries. The real first woman to fly between the two countries was Amy Johnson. Yes, that Amy Johnson. She was a complete unknown when she set off from Croydon, and only started attracting attention when she was in Asia and on schedule to break the record for fastest journey. When she eventually reached Darwin, she received over 500 telegrams, and a crowd of over 30,000 people welcomed her when she arrived in Melbourne. Shell received so many complaints about her route from people who wanted her to visit their town that they had to put an announcement in the paper that it was nothing to do with them.
Miss Fisher is not an unknown. By the time she leaves Australia, she is the daughter of a Baron and the niece of one of Melbourne's more respectable matriarchs. She has directed a box-office breaking film after investigating the murder of its much-loved star, organised a tennis tournament and investigated the murder of a rising tennis star, and additionally been involved in the investigation of the murders of a hugely popular and successful football player, a noted theatre actor, a well-known French artist and a racing driver.
It's no wonder she had Frederick Burn outside her house. She was already a celebrity, before she set off on such a ridiculous endeavour. She's the sort of woman who gets featured on stamps, and in ranges of inspirational books for little girls. She has almost certainly been a Barbie.
The personal life section of her Wikipedia is just going to be a list of notable men she was rumoured to be engaged to and then Jack, at the bottom of a 10,000 word essay about all the other ridiculous shit that she did, and it will double in length when the Official Secrets Act expires.
