Enjoyed your video - I love that area. If you don't mind some advice from a dinosaur who learnt from 60 and 70 year olds who were still making a living panning in the mid-1960s. I could still sometimes get a third of an ounce panning over a single weekend then - none of these microdots (golden flyspots).
1. Everyone pans close to crossings (ever since horse and cart days). Take time to get further away from them, even setting up a camp for days in one spot that you have to bush-bash into.
2. Your first rock bar was a reasonable location - if it dipped downstream not upstream. If rock bars dip downstream pan on their upstream side - if they dip upstream they are probably less interesting, although there will be alternative gold traps there. Simple applied hydraulics.
3.Panning techniques - take more time, use a big pan, and don't try and wash coarse pebbles over the lip with the fines. I was taught to use my fingers like a rake and scrape the pebbles out of the back of the pan. When no large (eg 1 cm) pebbles left, start panning and take more time to concentrate. After swirling initially, scrape coarse stuff over the lip, re-concentrating by swirling, until down to a few mm sizes. Then re-concentrate and do gentle rocking back and forward over the lip (not swirling), so only the top layer washes over the lip. Re-concentrate by swirling regularly, then back and forward rocking again, washing the top layer gently over the lip. When you get down to a few tablespoon full, very gently swirl washing away from the down-dip side where you have been concentrating and your gold should be seen (usually with black sand if you have been doing it efficiently).
Please consider a winching course through Four Wheel Drive Victoria - I have had a number of workmates killed by winches through my life. The way you are doing it is unsafe. A broken winch table can take the top off a 4x4 cabin - and the head off a driver.
