The farm was aimed at helping Fonterra and its partners to increase local milk collection, improve milk quality and lift farmer incomes.
Ms Levelink and her partner Jonathan Verkerk milk about 400 cows and she also runs her own farm advisory and training business.
She has previously travelled to Indonesia and Africa where she worked and volunteered in similar lines of work.
She saw the Sri Lankan trip as "another cool opportunity" and she found it a very interesting experience, with a full programme.
A factory packaged milk powder from New Zealand and also processed fresh local milk.
That milk was produced by small-scale local farmers, who might have two or three cows. A larger cow owner might have 15.
An average supplier was providing 10 litres of day. To put that in perspective, the daily pick-up from all farms in Sri Lanka was about 20,000 litres, while Ms Levelink's farm was supplying about 8000 litres.
People milked their cows by hand, with a bucket, as they could not afford technology if they only had two or three cows.
The biggest challenge was the climate. While major flooding last year meant her trip was postponed, rain was now desperately needed.
From the cow's perspective, it was feed quantity and mostly quality. In the tropical climate, grass was never going to be as lush as West Otago, she said.
Mostly, the cows were a tropical breed crossed with a Jersey. They were very small, probably weighing about 300kg-350kg.
While Ms Levelink believed there was potential to grow the Sri Lankan industry, it was "all in a very different perspective".
Eighty-five percent of fresh milk in Sri Lanka was produced by small-scale suppliers. A lot of people would have a cow or cows to milk for family consumption and, what was left, went to Fonterra. Then there was a group of farmers that had dairy as their primary source of income and that was the group that Fonterra's supplier relationship officers were working more closely with.
The Sri Lankan Government would love to be self-sufficient but, at this stage, the average consumer was only consuming about a quarter of the daily recommended intake of dairy products.
"It's got potential but in its own way," she said.
She found the Sri Lankan people to be very enthusiastic and warm. The crew within Fonterra were very passionate about their work, as were the farmers, and they were all interested in exchanging information.
She would love to go back in the future as she believed there would be a lot of differences.
