Canberra cycling Chloe Hosking has been added to Australia's team for the world championships after a double injury blow two weeks before the event.
Hosking and Jessica Allen will replace Grace Brown and Sarah Roy, who have both been ruled out of the races in Yorkshire from September 22-29.
Hosking, who won road race gold at the Commonwealth Games last year, and Allen, a former junior world champion, will be a part of a 20-strong team, which also includes Canberra's Michael Matthews and Rory Sutherland.
The road world championships features eleven races over eight days in the junior, under 23 and elite categories.
The road races will be a punishing 285km contest for the men and 150km for the women, with both races to culminate with laps of a technical circuit around Harrogate.
