The annual koala count has taken place this weekend in Narrandera.
The half-day outing helps to gauge the strength of the town's colony, by comparing the population's growth between years.
This year, a spokesperson for the National Parks and Wildlife Services (NPWS) confirmed up to 46 koalas were spotted.
That included four baby koalas seen clinging to their mothers' backs in the trees.
"A lot looked quite young, which is very exciting," said Kimberley Beattie, koala committee member.
"It's good to see they've had such a successful breeding season."
Despite the cold and wet conditions, up to 250 people took to the Flora and Fauna Reserve, near Cadell Street for the tree-spotting event.
"That might've been the largest group we've had so far," said Ms Beattie.
It was an especially impressive record given the dubious weather in the week leading up to the count.
"The rain held off, but it has rained on previous days and we were worried we'd have to call it off," Ms Beattie said.
"It can rain all it likes now that we've done the count, and hopefully it will because we still need that rain.
"Thankfully it was not too windy, but it certainly was cold."
Koalas were released into the nature reserve in 1972 to re-establish a colony that had disappeared around 1900 and they had since spread down both sides of the Murrumbidgee River.
Organised by Narrandera Tourism and Narrandera Shire Council, the event is usually held in autumn.
"We might keep it in spring, that hasn't been decided yet," Ms Beattie said.
"The babies are more visible at this time of the year, because they're getting bigger and starting to venture away from their mums a bit more.
"In previous years, we haven't seen so many babies."
Last year, it took place in May, and also confirmed a thriving colony of the marsupials.
"It's getting to be pretty normal to see between 30 and 40 of them," Ms Beattie said.
