At the start of 2020 no goats roamed more than 50,000 hectares of the Wilcannia properties owned by Ross Gates.
But now there are some 12,000 nanny goats and the use of embryo transfer is only set to speed up the drought restock.
Mr Gates and his partner Nicole Seakamp run 12,000 nannies themselves, and have another 3000 that are run on a share basis; halving the weight gains with the partnering parties.
"A lot of people after the drought aren't able to restock, so do a share deal," he said.

At the start of 2020, no goats remained on the 27,000 acre (10,927 hectare) property Coonoolcra Station, or the 100,000 acres (40,469 ha) they also own known as Keelembara.
But in April they were able to restock, buying goats from Queensland and depots that held on to nannies.
"That is the good thing about goats - you don't get attached to bloodlines so you can sell up the lot when things get tough, and start again, without worrying about keeping genetics," he said.
"We probably got 3000 to 4000 out of Queensland, with the rest from local areas within 300 to 400 kilometres of this place."
Mr Gates said coming out of the drought it was hard to find large numbers of good goats because it had been so dry for too long, and people had to kill everything.
"No one has numbers of Kalahari nannies," he said.
"We wanted as many (does) as we could, and we went in knowing we wanted to spend between $5000 and $6000 on them," he said.
"We should have went harder on some... There are no nannies around so you have to buy what you can get when they are available."
Included in the draft was the top-priced black doe they bought for $6200.
The two bucks from Rangeland Red that averaged $5500 will go across the Bunnaloo nannies, Mr Gates said.
"We looked at birth weights and what they were at 12 months... we want them born little, but with the ability to get big as quick as possible," he said.
The five Bunnaloo does will enter into an embryo transfer (ET) program at the van Niekerk's to help Coonoolcra Station increase their commercial numbers while improving quality.
"We would only have 500 bore nannies at the moment, the rest our rangeland," he said.

They hope to increase the Bunnaloo does' reproduction rate to eventually breed enough purebred nannies to be able to breed their own bucks to keep and use.
"We're hoping to get 10 kids off one nanny a year through ET," he said.
They usually have a kidding percentage of 150 to 200 per cent.
Looking at the buck to nanny ratio, Mr Gates said they could need 500 to 600 bucks to continuously reach their goals.
"Rams run at three per cent, I'm thinking we wouldn't get away with that," he said.
"We might need to run more bucks. It might be five to six per cent."
Mr Gates at times might trade a couple of 1000 sheep per annum with Dorpers a preference, but it is otherwise solely a goat operation with all stock fenced in.
It has been this way for at least 20 years, he believed.
They sell their nannies to the restocker market in Queensland and the rest to abattoirs, either skin-on or skin-off.
"Since the government did work with exclusion fencing in Queensland, the restock market has been pretty generous," he said.
"It has boosted the market big time, because previously no one could run small animals up there - now they can.
"The skin-on market is the one you want to be at. Ideally if you are just breeding goats, 99pc of your goats can target the skin-on market.
"Billies only convert well into the high 30 kilograms. If you try to grow them out to 45 to 50kg they take a while, whereas if you target the 36 to 38kg they do it relatively quickly.
He said they were better off getting rid of them at a lighter weight.
