Haven't had the time to relook at this - and forgot to reply. You can see the website here https://www.ecomad.com.au/Ecomad2022/ and see how the logo is not working well once you start to scroll down.
Also if you check different screen sizes the website is pretty good, just doesn't look as good in the header and menu. Have a look on your phone in portrait. The logo is centred which is ok, but the menu 3 lines to expand drops down a line making the header too thick (black background).
Tried to do some custom.css to fix up but not having any luck.
