Australia currently allows two kilograms per person, but the government is considering doubling that to four.
In submissions to Australia's Office of Drug Control, Fiji's government proposed a quota of 10 kilograms per person, while Vanuatu suggested 15.
The director general of Vanuatu's foreign affairs department, Kalfau Kaloris, said he didn't believe 4 kilograms was enough - particularly if it's to be used at a large ceremony.
Australia's restrictions on kava are driven by concerns about its misuse in remote communities.
