TASMANIA'S world championships rowers set up a busy day in the repechage after day two of the regatta in South Korea.
Huon's Georgia Nesbitt was the most successful Tasmanian, with her lightweight quad scull becoming the first Australian crew to advance to an A final.
Also featuring Alex Hayes, Georgia Miansarow and Hannah Clark, the crew found itself in third place at the half-way point of its heat.
Knowing only a top-two finish would provide automatic qualification, the Australians dug deep to pass Russia in the third 500m of the race and set their sights on the pace-setting Americans.
In an exciting race to the line, the US held off a fast-finishing Australia with both progressing to Friday's final.
The new-look Australian men's lightweight four combination of Tamar cousins Ali Foot and Blair Tunevitsch with Queenslanders Nick Silcox and Darryn Purcell slotted into fourth early in its heat and despite progressing to third over the last 500m was unable to book an automatic progression.
The crew will turn its attention to the repechage as Australia continues to rebuild its depth in a boat in which Tasmanians Anthony Edwards and Sam Beltz won a world championship two years ago.
A men's eight containing former Tamar rower George Ellis is also heading for the repechage after finishing fourth behind the European crews of the Netherlands, Poland and Germany.
The Australian highlight was the dominant display by dual Olympic medallist Kim Crow, girlfriend of Lindisfarne's 2008 Olympic champion Scott Brennan, who recorded the fastest heat time in progressing straight to the semi-finals.
