Katie Walsh failed in her quest to emulate her brother Ruby as I'll'ava'alf was brought down in the Australian Grand National.

Ruby Walsh won the Ballarat feature aboard Bashboy in 2015 but Katie's attempt to land the extended two-mile-six-furlong event came to an end when her mount was brought down by Slowpoke Rodriguez at the last fence.

Wells, a previous winner of the race in 2014, eventually ran out a 10-length winner of the race.

Walsh had also featured as part of an Australia versus Ireland jockeys' challenge, with the home side securing a comprehensive success.
