Teaming up with Victorian Alice McNamara, the 25-year-old Huon rower finished second in the women's lightweight single sculls in Lucerne.

It was one of three silver medals won by the Australian team along with Kimberley Crow in the women's single scull and Alexander Belongoff and James McRae under the guidance of former Tasmanian Institute of Sport coach Rhett Ayliffe in the men's double sculls.

Australia made nine A finals at the final world cup event of the season ahead of next month's world championships in Amsterdam to finish third overall.

Flecker and McNamara had a point to prove having won their semi-final over world champion Italy.

Coached by Mark Fangan-Hall, they powered through the race to keep up with Great Britain's Katherine Copeland and Imogen Walsh and fended off a challenge from Olympians Lindsay Jennerich and Patricia Obee, of Canada, to claim silver.

 Flecker and McNamara attributed some timely words of wisdom from national head coach and multiple Olympic champion Drew Ginn for helping them turn around their form from the previous world cup in Aiguebelette.

``Drew put us in a room for a big chat and just whipped us into shape,'' McNamara said. 

``The turnaround was mostly mental rather than physical, we built trust and camaraderie over the two weeks in Italy, before came here to compete. Drew made us realise what we hadn't seen.''

In one of several tight finishes, New Norfolk's Kerry Hore and her crewmates Jessica Hall, Madeleine Edmunds and Jennifer Cleary finished fourth in the women's quadruple sculls won by Germany.

Tamar's Alister Foot and Darryn Purcell finished fifth in the lightweight men's pair and it was the same result for their Tasmanian colleagues Blair Tunevitsch, Tom Gibson, Sam Beltz and Nick Silcox in the four.  The Australian men's and women's coxed eights both finished sixth.
