In the latest chapter from the epic trip, hundreds of spectators lined the roads leading to Longreach to watch the 1600-strong mob of cattle meander across the old bridge over the Thomson River on Sunday.

As tourists, campers and locals took photographs of the procession, Senator Barnaby Joyce, Federal Member for Maranoa Bruce Scott, and State Member for Gregory Vaughan Johnson led the cattle on horseback.

With ballot day for the federal election looming, Senator Joyce told the crowd that the Federal Government had no idea how to tackle the issues that were adversely affecting the bush, and encouraged voters to change the government.

The LNP held a dinner in the town the previous night at the Qantas Founders Museum, where Federal National Party leader Warren Truss told the gathering that rural Australia was hurting in many ways, but was resilient and passionate about continuing to be a major contributor to the nation's success.

The unique political protest left Cloncurry with 140 head of cattle on May 9 and is set to arrive in Roma in October with more than 2000 head of cattle, with an ever-expanding donation of beasts coming from a wide range of bush outlets, including Hughenden, Julia Creek and Mt Surprise.

The next major stop for the cattle is Barcaldine in a fortnight, where the cattle will be used as part of a local campdraft event.

LNP state president Bruce McIver said the drive aims to give a voice to rural Queenslanders.

He said locals along the route were responding enthusiastically to the opportunity to have their voices heard.

"It is increasingly clear to locals that the LNP is the only party that understands them," he said.
