The most extraordinary feature of the draw is that, if I'm reading it right, every single one of 16 qualifiers has drawn another qualifier in R1. I wouldn't have any idea how to calculate the odds of this, but I'd presume that it's a few billion to one.
If Jo beats Brengle she has Gasparyan or a qualifier in R2.
Thereafter potentially among this little lot from the top quarter if the seeds take their L32 places ( and that's probably a rather big if ) :
(1) Halep vs (27) Kvitova (18) Barty vs (16) Vesnina (9) Konta vs (20) Strycova (29) Safarova vs (6) Ka Pliskova
I have Heather beats Putintseva she has (11) Mladenovic or Bogdan in R2. Kiki is on an awful run, 14 successive losses stretching back to R2 of the Washington International tournament at the start of August. She retired in the second set of her match this week in Sydney.
Margarita Gasparyan (RUS), age 23, CH 41 in February 2016.
No activity for 15 months after retiring from her R1 match at Wimbledon 2016. Her two tournaments towards the end of last year didn't get her a ranking. In the draw based on a SR 62. Doesn't appear to have played a pro match this year so far.
