Harriet Dart was the only Briton to make it through to the second round of qualifying for the Australian Open.
Dart, ranked 169, needed just 75 minutes to beat Bulgaria's world number 194 Elitsa Kostova 6-4 6-1.
She will face American 15th seed Nicole Gibbs next.
There were defeats for Liam Broady, Jay Clarke and Nakitha Bains on the opening day of qualifying in Melbourne, where the effect of bushfires on air quality was again a significant concern.
Broady was thrashed 6-3 6-0 by Belarusian Ilya Ivashka while Clarke fell 7-6 (7-2) 3-6 6-2 to Blaz Kavcic of Slovenia.
In the women's competition, Bains lost 6-2 6-2 to Russian Valeria Savinykh.
