Australia’s men completed a home double at the World Rugby Sevens Series, beating defending tournament and current men's champions South Africa 29-0 in the final at Allianz Stadium in Sydney after their female counterparts had won their final 31-0 against New Zealand.

It was an all-Australian sweep on the Australia Day long weekend.

The men’sfinal victory was Australia’s first since Tokyo in 2012 and moves them up to third in the Seven Series standings behind South Africa and New Zealand.

Argentina finished third after beating the United States 31-10 in the bronze medal final.

The men’s final concluded three days of action and saw the only two unbeaten teams do battle for the title.

Australia outplayed South Africa right from the kick-off, scoring five tries while keeping the opposition scoreless with aggressive defence.

Australia’s Lachlan Anderson, an emerging talent within the team, was voted player of the final.

"It is still hard to take it in and it is pretty special, but we have been talking about this for a long time," said Anderson.

"We started the work last July and drew a line in the sand as we hadn’t won for a while.

"We put the pieces in place and it’s great that we got the reward this weekend."

Earlier in the day in the first quarter-final of the day the US dominated possession to shut out Pool A winners and Olympic champins Fiji, while South Africa had too much physicality and class for Kenya.

Australia surprised their arch rivals New Zealand, while Argentina continued their improvement with a win over England.

In semi-finals Australia thrilled their fans to make the final at home by beating Argentina, finalists in the last World Rugby Seven Series event in Cape Town.

South Africa imposed their authority as defending champions and were too strong for the US.

The fifth place play-off saw New Zealand beat Fiji 31-7 and France beat Wales 29-12 in the Trophy final.

Australia’s women went through the tournament without conceding a try, a first in the Women’s Sevens Series.

In their final against the current Series champions they scored five unanswered tries.

Canada finished third after beating Russia 40-12 in the bronze medal final.

Player of the final was Australia’s Charlotte Caslick who steered her team around the field and scored a try herself.

The tournament win is Australia’s second in a row following victory in Dubai in the series opener and extended their lead in the Women’s Seven Series to 10 points over New Zealand, Canada and Russia.

Australia had lost their five previous meetings against New Zealand and Charlotte Caslick said after the match: "It was a fantastic way to finish the tournament here in Sydney in front of our home crowd especially as New Zealand are so tough to beat.

"Our coach Tim Walsh wanted a better defensive effort in this tournament as it was not up to par last year, so we have worked really hard on it and we finished without conceding a try which is awesome."

England beat Fiji in the Challenge Trophy final 29-10.
