The Fijiana XV overwhelmed Samoa 41-13 in the Oceania qualifying final at the weekend to book their ticket to New Zealand.
Head coach Alifereti Doviverata said qualifying for the World Cup is a "historical moment" that will enhance development for women's rugby in Fiji.
"It means a lot firstly, for the development of women's rugby," said the former Flying Fijians captain.
"I think it has come a long way since its inception in Fiji and the rugby development officers, the CEO and staff have been working tirelessly to get some recognition in women's rugby in Fiji."
