For the first time since 2006, the Sevens World Series stops over in Singapore this weekend.

Some of the most exciting international athletes will be sporting their fast, action-packed and entertaining styles of rugby at the National Stadium.

With only three tournaments left in the series and it being an Olympic year and all, the teams will be aiming to put on their best performances as they ready themselves for a major climax to the tightly contested series.

Heading into the Singapore Sevens, Fiji leads the standings on 128 points, five in front of New Zealand who they beat in the final of the Hong Kong Sevens comfortably. Australia finished fourth at Hong Kong and are in that exact position in the overall standings after their loss to South Africa, yet the Thunderbolts are still behind those three teams and are struggling to tighten the gap. However, they can find solace in the fact that they have reached four Cup semi-finals in consecutive tournaments for the first time in 15 years.

Injuries have damaged the Australian squad, including Wallaby Nick Cummins, who was ruled out of the action in Singapore after sustaining an ankle injury in Hong Kong. A long list which contains Tom Cusack (wrist), Pama Fou (shoulder), Nick Malouf (knee), Tom Lucas (knee), Simon Kennewell (ankle), Lewis Holland (foot), Greg Jeloudev (foot), Henry Hutchison (foot) and Henry Speight (eye) all join Cummins on the sidelines.

Halfback Josh Holmes, who has been training with the national Sevens program for the past month, will make his first appearance in an Australian jersey since 2007, while forwards Sam Figg and Pat McCutcheon have also been picked. James Stannard will captain the side in the absence of Ed Jenkins, who has been rested.

South Africa only make one change heading into the Singapore Sevens. Fifty-tournament veteran Chris Dry has been called up to replace Philip Snyman after he picked up a knock in the close semi-final loss to New Zealand in Hong Kong. Though the forward has passed the necessary tests for him to play, team management decided to play it safe and rest the forward with more tournaments and the Rio Olympics around the corner.

New Zealand have been forced to call in reinforcements after four players were ruled out with injury. Pita Ahki, Sam Dickson, Tim Mikkelson, and Lewis Ormond have all had to withdraw from the tournament this weekend after sustaining injuries in Hong Kong. They have been replaced by Antonio Kiri Kiri, Josh van Leishout and Isaac Te Aute.

Fiji head into the Singapore Sevens on top of the heap, yet they are nowhere near in a comfortable position. They are only five points ahead of New Zealand and six of South Africa. Besides a narrow victory over Kenya, Fiji cruised to their title victory in Hong Kong, which consisted of romps over Australia and New Zealand. The Fijians will want to continue the form they're in because any slip up could see them potentially drop down to third.
