Transport for NSW turned away people driving up to Perisher for two hours on Saturday.
In a "road turnaround" between 10am and 12pm vehicles were asked to head back, with parking at Perisher also becoming full.
An Instagram user filmed the queue which showed just how many visitors were headed to the ski resort to make the most of the fresh snowfall. Vehicles can be seen lining up for about a kilometre.
"We anticipated peak snow days this weekend due to our recent snowfall here at Perisher, which was communicated to our guests," Robert Lloyd, marketing director at Perisher said.
Even with reasonably strong winds, the majority of the lifts at Perisher were running throughout the day.
While guests were free to explore 3000 acres of terrain encompassing all four resorts, Mr Llyod asked visitors to come prepared.
"If you are coming up to Perisher this weekend, please plan ahead, catch the Skitube or shuttle if you can, and stay up to date on the latest weather and snow reports via the Perisher app," he said.
The resort received about 5cm of snowfall overnight, bringing a total of 32cm of snowfall in the last few days.
At Thredbo, the coat of fresh snow was about 10cm thick, according to the Bureau of Meteorology.
Winds are expected to weaken on Sunday with minimal snowfall in the alpine areas.
"We will still see a couple of showers ... maybe a little bit of snow but not a huge amount today. Tomorrow we may see another little dusting of snow, but it's more likely we'll see some showers around on Tuesday as the next system moves through," a Bureau spokesperson said.
