She currently holds the last (non-continental) qualification spot, edging out Ireland's Darragh by 33 points. I don't know if either of them (or Hungary's Sandorhazi) are competing this week so it'll come to end. Additionally, she needs to hope New Zealand's Shaunna Li doesn't break into the top 250 (currently 259) or else she will get the continental quota (though if she did, New Zealand may decline the quota).
On the opposite side, Australia must select which two events between men's singles, women's singles, women's doubles and mixed doubles will get the continental quota, the others will be reallocated to the next highest ranked nation so even if Bulgaria gets passed she might get the quota if Australia doesn't choose women's singles.
