One day he drove from Longreach to north of Bourke to catch up with a farmer there, help him “feed a few sheep” and have a few beers.

He’s traversing the countryside to meet up personally with farmers donating hay and is currently tidying up the “final 1 per cent” of preparations for the 12th Burrumbuttock Hay Run to far north Queensland on February 23.

And, as they say, the devil’s in the detail so it’s these final, finicky details that will keep the convoy on the road and ensure much-needed supplies once again get to drought-ridden farms.

It’s an understatement to say this is a massive undertaking – Mr Farrell will tell you straight up it’s a logistical nightmare.

He admitted this run was a lot more spread out in terms of hay collection and mustering a fleet of 140 trucks.

On Monday he put a call out for more trucks.

It’s a measure of the man that less than 23 hours later, he was so inundated with offers from across Australia that he posted on Facebook that he was full up.

It was his birthday on Tuesday.

Ask him if he’s exhausted and he’ll laugh.

“To be honest mate, I’m f---ing over it,” he said.

”I need to lock myself in a dark room for a day and just nut it all out in my head.”

In addition to the hay run, Mr Farrell is grappling with the other logistical challenge of staging a final day concert for 1000 in an outback town with a population of 50.

“I’m worrying about security guards, toilets, showers … I mean there’s no five star hotels in Muttaburra mate.”

This is a man who’s never off the phone, yet he’s always available to chat.

One wonders if he sleeps.

But this knockabout no-nonsense bloke, who’s helped 8000 farmers in the past four years, wouldn’t have it any other way.

“At the end of the day when you put your hand up to do something, you have to keep going,” Mr Farrell said.

“That’s what I teach my kids – whatever you do, do it well.”

As he prepares to get rollin’ once again, you know there’s a lot of farmers bloody grateful he’s headed their way.
