The Fiji 7s team moved into the overall lead in the race for the World Rugby Sevens Series title as they thrashed Australia in the final in London.
They are two points ahead of the United States, who beat France 31-14 in the bronze medal match, with just the series finale in Paris to come.
Fiji, who secured their place at the Tokyo 2020 Olympics along with the US and New Zealand yesterday, have 164 points.
The US trail by two points on 162.
It is a straight battle between the two countries for the overall title, which will be decided in Paris this weekend.
New Zealand have the faintest of chances of snatching the crown but can only lift the trophy if they win in Paris and Fiji and the US endure disastrous outings in the French capital.
