I was on the FHAC a few days ago and recorded entries from Dibbins and Derrick Huts.

This is 51 people in 2.75 years. Allow three people for the May 2022 party, giving 53 people, less 8 skiers is 45 people. That is, for green season there are 17 people a year

This is 33 people in 2.25 years. Allow two parties of 2 people each in January and April 2024, giving 37 people, less 10 skiers is 27 people. That is, for green season there are 12 people a year.
If the numbers are underestimated by a factor of five this is 100 people a year in green season.
On 24 November 2016, Parks Victoria released the Draft Management Plan (DMP) for the proposed Falls Creek to Mount Hotham Alpine Crossing (FHAC) bushwalk. Page 87 says:
"There are an estimated 17,000 walker nights per year on the trail".
This means that there are that many people in mid to late 2016, not a projection.
The FHAC walk has three campsites: Cope Hut, Tawonga Huts and Dibbins Hut. If 100 walkers stay at these places then there are 300 walker nights. The maths is easy – 17,000/300 = 56. That is, the DMP 17,000 figure is out by over 50 times.
An alternative is that the popularity is falling, down by 98%.
If anyone goes to the FHAC huts, please record the number of people on FHAC and post here in the above format. Entries from Cope and Tawonga Huts would be useful.
