The first British woman to reach the quarter-finals of a grand slam event in 32 years might have been the only Australian survivor, but for her parents' decision to leave the fatal shores when she was 14. 
Australian tennis lost Sydney-born Johanna "Aussie Jo" Konta to mother England, not because of inducements from the rapacious Brits. Nor was the defection due to some lost bidding war, or a falling out between Tennis Australia and the Konta family.
No, Konta, is a case of a player following her Hungarian-born parents, after her father took a job with a London hotel, the Marriott Docklands. "You can't tell people where to live," said one Tennis Australia insider.
Win a Gavrilova, lose a Konta. Australia, on the whole, gains more from the passport free agency market than it loses. But the loss of Konta is more keenly felt since Daria's done her dash.
Konta, according to Australian tennis folk with a memory that stretches back beyond a decade, was a capable but not spectacular talent in her early teens. By 2012, she was swearing allegiance to the Union Jack and reportedly shedding tears at the London Olympics.
Konta, unsurprisingly given the thin ranks of Aussie women, was asked (after defeating Venus Williams) whether she'd consider a return to Oz. "No. Unfortunately, my home is Great Britain. It has been so for a long time now, over a decade ... that's where my heart is."
Pat Cash, noting that he lived in London for 30 years and never defected (as some might prefer), wrote in the Sunday Times that Konta should not be subjected to interrogation about leaving Australia for the UK.
"For goodness sakes," Cash said. "Look at our Davis Cup and Fed Cup teams? Yes, Russia can probably scratch together a women's team without Gavrilova and the Rodionova sisters. But what would these Aussies have had to say if Greece, who can be found down in the Europe Zone Group three with the likes of Andorra, Iceland and Ireland, started claiming Kyrgios and Kokkinakis for their team?"
No one was complaining or talking much about Konta turning British this time last year, when she was ranked 150 in the world, aged 23. Aussie Jo's arrival as a serious player - she's ranked in the low 30s now, almost identical to Aussie Daria - began mid-last year after a good performance in Eastbourne, her home village. But she really came to notice at the US Open, when she upset a couple of seeds en route to the last 16.
Konta will have her share of support in her quarter-final against China's Zhang Shuai.
