There has been a lot of Nepalese nationals arriving in Sydney in recent years, perhaps in the last 5 years. I can't remember which document said it but it was I think a jump of 100% year-over-year. This document mentioned that in the first half of FY2019, passengers coming from Nepal is the fastest growing nationalities that has arrived in Sydney, more than The States, India, Indonesia, and Vietnam.

I think as cuteguy said, the shops might want to appeal to the increasing Nepalese nationalities, and perhaps also explain the increasing number of Nepalese girls that are available. Granted, they might be tourists, and here for a short-time but, still, a possibility.
