Cate Campbell has had a big 2019 and has now helped her team into the ISL finals

Cate Campbell is again in the money after helping London Roar qualify for the inaugural International Swimming League final.

But the Australian sprint queen could not stop an undefeated Energy Standard team upstaging the Roar and winning the London leg of the lucrative 25m, short course ISL series on Monday (AEDT).

Former world champion Campbell, 27, was already buzzing ahead of the ISL's London round at the 2012 Olympic pool after claiming more than $400,000 from the recent World Cup series.

She picked up $A200,000 over the seven leg series before being awarded another $A220,000 as the overall women's World Cup champion.

Campbell is now cleaning up in the maiden ISL series, reportedly earning more than $A11,500 at the two-day London leg after collecting $A23,500 over two earlier rounds.

She helped Roar qualify for the ISL final to be held at Las Vegas from December 20-21 - which features the top two European and US teams - where $A14,500 goes to each swimmer for the winning outfit.

The Roar - who also feature Australians Minna Atherton, Emma McKeon and Alex Graham - will take on fellow European outfit Energy Standard and American teams Cali Condors and LA Current in the final.

The Roar are expected to welcome back Australia's Kyle Chalmers for the final after he missed the London leg.

Energy Standard won the London round on 467.5 points ahead of Roar (458.5pts), Iron (369.5pts) and Aqua Centurions (335.5pts) despite Campbell's best efforts.

The former world record holder claimed the 100m freestyle on Monday, with McKeon second.

Campbell and McKeon also combined to feature in Roar's mixed 4x100m freestyle relay win.

Backstroke queen Atherton chimed in with Campbell and McKeon in Roar's women's 4x100m medley relay triumph.

Atherton - who missed the 200m backstroke world record by 0.02 of a second on Sunday - also won the 100m backstroke on Monday with Australia's Emily Seebohm (Energy Standard) third.

Atherton, 19, broke the 100m backstroke short course world record at the last ISL leg in Budapest last month.

The ISL is the brain child of Ukrainian billionaire Konstantin Grigorishin who has budgeted $A29 million for the inaugural season with more than $A10 million going to athletes in prize money over seven legs.

More than 100 Olympians are represented in the ISL, including 41 gold medallists from the Rio 2016 Games, which features straight finals and a team point scoring format.
