After weeks walking the dry and dusty stock routes of western Queensland the first mob of Brinkworth cattle are about to cross into New South Wales at Mungindi.

South Australian pastoralist Tom Brinkworth bought 18,000 head of cattle from the Australian Agriculture Company earlier this year and controversially decided to walk them to his property "Uardry", near Hay in the Riverina.

The drovers and cattle have been split into nine mobs and have spent the past three months meandering their way down the long paddock.

Boss drover Bill Little has been droving for 30 years and says the size of the operation is the largest he's seen.

"It's probably a bit of history," he said.

It was expected the cattle would take different routes as they headed south but the ongoing drought means there hasn't been enough water.

"We would have loved to have sent some of them Cunnamulla way and we would have loved for some of them to go down the Maranoa River, but water is a bit too tough that way, so we will all have to come in here at this stage."

The stock routes they have chosen haven't all been smooth sailing though.

"Around Roma we were pumping a bit of water with our own pumps as well, there are some waters that are low and if you put a big mob of cattle in them they muddy the water up and wreck it pretty quick," Mr Little said.

"Rather than spoil the water we actually fence it off with our electric fences and then pump it into our own troughs."

Some western Queensland councils were concerned there wouldn't be feed and water to support such large numbers.

The Winton Shire Council had refused the project permits to pass through its stock routes but its decision was overturned by the Queensland Government.

The Department of Natural Resources found that after inspecting sections of the route there was adequate feed and water available along the route and revoked the Council's refusal of the application.

Another issue with droving in the 21st century is dealing with traffic and people who aren't familiar with how to behave around animals.

"Probably the most concern is traffic. I think traffic all day. I think controlling the traffic, getting up on the road and slowing them down. That, and the well being of the cattle," Mr Little said.

Helping keep the mob on the road is Alonna Laing.

While her partner Bill and the drovers look after the cattle, Alonna is in charge of the camp.

"I pack up, shift the truck and set-up. And we do that two times a day," Ms Laing said.

She says things haven't changed a lot since the droving days of old, but some modern conveniences are welcome.

"We have a stove instead of a campfire, but some nights we cook on an open fire."

Alonna has a full-sized fridge, stove and cupboards on the back of a truck, and it certainly makes life a little more civilised.

"It's pretty much a standard sized kitchen," she explains. "Just on wheels!"

"We eat a lot of beef," Alonna explains. "Throw in a few onions, some tomato sauce, fresh bread. Lovely."

"Beef is generally the cheapest food, surprisingly enough!" she laughs. "We'll often kill on the road. We normally put in a few 'killers' into the herd."

Contract musterers and travellers have also stoped by and hopped on a horse for a day and some have stayed for a few weeks.

Fiona Wilson is a Victorian teacher on long service leave and after stopping to speak to the drovers she ended up getting into a saddle.

"I met a local fellow and I went and helped him do something and then all of a sudden I'm riding a horse helping lead cattle across a bridge. It's interesting the people you meet."

When they reach the NSW border at Mungindi the cattle will have to be split into smaller mobs of 1500 head and extra drovers will be needed.

"The costs change. It's dearer in NSW but we're not trying to feed so we'll just elect to take the walking permit," Mr Little said.

"Things won't change that much but we will have a fair bit more opposition because they agist a lot of their stock routes out to locals."

It's expected the first mob will reach their destination in southern NSW by Christmas time.
